Sal Suds Dilution Cheat Sheet

There is a lot of overlap here with the Castile Soap Dilutions Cheat Sheet because the products can often be interchanged. It is largely a matter of personal preference, but the Sal Suds is more clean-rinsing in hard water situations, and is slightly more effective on grease and tough stains. As with the castile soaps, these recommended dilutions are not set in stone. You may have dirtier stuff, larger sinks, a larger washer, etc., and may need to tweak these amounts to your own situation.

Dr. Bronner's Sal Suds dilutions cheat sheet

What Sal Suds looks like in my house, from most concentrated to least, left to right: Undiluted gallon for the laundry room, Undiluted quart for easy handling when making other solutions, Diluted Dishwashing squirt bottle, All Purpose Spray for most things, Sal Suds Lite for windows and less dirty stuff.

This list doesn’t name every possibility but shows that there is very little that can’t be cleaned with the Suds. The long and short of it is, if it’s not on this list, then I probably didn’t think of it. Sal Suds is safe for any surface or material that can get wet (but it’s not meant for people or animals – it can be drying). However, if you have something that’s iffy, do a spot test.

Dilutions:
Laundry: 2-3 Tbsp. for a large load in a top loading washer. Optional: ½ c. baking soda in wash cycle, 1 c. vinegar in rinse cycle. Use half these amounts for HE washes
http://www.lisabronner.com/?p=127

All Purpose Spray: 1 Tbsp. Sal Suds in a quart of water. Put the water in the bottle first. Use on most of the aforementioned surfaces
http://www.lisabronner.com/?p=180

  • All Purpose Spray is also used for the following:
  • Stainless Steel Sink: Spray and sprinkle with baking soda from a shaker. Then scrub.
    http://www.lisabronner.com/?p=535
  • Microsuede: Spray and scrub with a gentle circular motion.
    http://www.lisabronner.com/?p=657
  • Wood: Painted or Sealed (not waxed) – Spray and wipe with a microfiber cloth
    http://www.lisabronner.com/?p=710
  • Toilets: Empty toilet, spray bowl thoroughly, sprinkle baking soda on the brush, scrub bowl, let sit 10 minutes, turn water on, flush.

Carpets: 1 drop of Sal Suds in a carpet cleaner with hot water; All Purpose Spray for spots (use sparingly)
http://www.lisabronner.com/?p=491

Veggie Wash: 1 drop of Sal Suds in a bowl of water. Dunk and swish the produce. Rinse

Window Wash: (aka Sal Suds Lite) ½ tsp. in a quart of water. Put the water in the bottle first. Spray and squeegee. Follow up with a spray of pure club soda, or half vinegar/half water, and squeegee.

Dish washing by hand:
Pre-diluted: (my preference) ½ c. Sal Suds in a quart of water in a squirt bottle. Fill with water nearly to the top before adding Sal Suds.
Undiluted: ½ tsp. Sal Suds in a large sink of water. 1 drop Sal Suds for one pot.
With All Purpose Spray: http://www.lisabronner.com/?p=169

Mopping: ½ Tbsp. Sal Suds in approximately 3 gallons of hot water. 20 drops tea tree oil optional. Put the water in the bucket first. Dunk mop (microfiber, preferably) and wring thoroughly.
http://www.lisabronner.com/?p=299

Cars: ½ Tbsp. in a 3 gallon bucket of water. Put the water in the bucket first. Wet car down with hose. Wash with large sponge, or soft microfiber cloth. Rinse with hose before Suds dry.

  1. Hi Lisa,

    I am wondering: is the Sal Sud soap safe to use to clean the Diva Cup? If so how should I dilute it?
    Thank you,

    Josianne

    • Hi,
      I am not sure about the sal suds for the diva cup, but I use the unscented baby mild Castile soap (dr. Bronner) and it works great.

    • I wouldn’t use it for you Diva Cup as Sal Suds contain Sodium Lauryl Sulfate which is a carcinegen.

    • Hi Maiken – I’m glad you brought this up. There is such a lot of mix-up out there between Sodium Lauryl Sulfate (SLS) and its cousin Sodium Laureth Sulfate (SLES). Sodium Lauryl Sulfate (SLS) is in our Sal Suds, but it is not a carcinogen. Check out this article I wrote about this very question: There Is No Cancer Risk from SLS. Please let me know if you have any questions about it.

    • Sal Suds would be an excellent way to wash a Diva Cup as it is very effective and clean rinsing. The Castile, as Corrina points out, is another great option. I too would use the unscented.

  2. Hi Janie – Yes, the pure castile soap does react with the minerals in hard water. Here’s a nifty little video I did that demonstrates this: http://lisa.drbronner.com/?p=365. In washing our bodies, this isn’t really a problem. However, in washing shiny surfaces around the house, or in the laundry, it can leave a residue. Sal Suds does not have this issue and if your water is particularly hard, would be the best option for household purposes.

    Hi PaulaLyn – Yes, the Sal Suds is a fabulous option and I think you’ll love the results. As you’ve said, vinegar is a no-go because its acidity eats soft stones, which are very popular nowadays. However, using the Sal Suds spray with a not too stiff scrub brush works really well. You can also sprinkle on some baking soda (which is alkaline) to add some extra scrubbing power.

    HI Josianne – Yes, the Sal Suds would work well on the Diva Cup. You would just need a drop or two in the cup, or if you wanted to do it in a sink, add a couple drops of Sal Suds to a sinkfull of water.

    All the best,
    Lisa

  3. Hi Lisa,

    So far so good with the sal sud’s. I’m trying to use it as the sole household cleaner of a very large meditation campus. I don’t see anything about concrete here. We have a large concrete kitchen(treated with something that makes it look green.I don’t know what it’s treated with..), and 2 large concrete Dining rooms with long concrete breezeways. We currently use Simple green Pro HD on the kitchen and FGS conditioner on the breezeways. It’s confusing having three floor cleaners at the center. One for residences(sal sud’s),one for kitchen, and one for dining room makes training difficult as each course the student’s themselves mop when they finish a course. What do you say about Sal suds on concrete, and if it’s safe long term, what dilution would you use for a greasy/grimy kitchen floor and soiled-by-dirty-shoes dining rooms and breezeways?

    I am a fan of your product and would love to make it the ALL purpose cleaner of the center instead of different products for each area.

    Sincerely,

    Sergio- western MA

  4. Hi Sergio – I would absolutely just use Sal Suds on all these different floors. For that greasy kitchen floor, maybe up the Sal Suds to 1 Tbsp. in your 3 gallon bucket – you’ll know if that’s too much because you’ll have leftover bubbles and no more grease for it to bond with. Sal Suds is equally effective on plain old dirt. Fiddle with that ratio until it is effective without extra bubbles. It will not harm the concrete nor the finish on it.

    All the best,
    Lisa

  5. Hi Lisa,
    I am interested in trying to be more “green”. I’m wondering if this sals suds soap kills germs? I want to make sure if i am using it to wash hands after touching raw meats and for washing dishes and such that it will kill the germs… Thanks!

  6. Hi Lisa, I’m a huge fan of your baby mild castile soap and use it in a lot of ways around the house including bathing my baby with it. I was also planning to buy Sal Suds for laundry, dishes etc but happened to read one of the reviews in amazon which said that coco betaine was named the allergen of the year in 2004 by the American Contact Dermatitis Society. Is it really that bad or can I use it for washing my baby’s bottles, clothes etc and what precautions should I take to ensure that it can’t cause any harm to the baby ?

  7. Hi Lisa,

    Can it be used to clean keyboards, monitors and PC equipment devices and accessories from the outside (plastic)?

  8. Hi,

    I’ve been using the sal suds as a dish wash and all purpose spray for 2 days since I got it in few days ago, it work great and do a good job at home, but I find out it is a bit too strong for my skin, after I use it I feel so dry on my hand, is that normal?

    I do a ½ cup in 946ml water for hand dish wash, and I do 1 TBSP in 946 ml water for all purpose spray.

    Carol

  9. Is this animal safe? I have cats, dogs, reptiles and birds. (I live in a zoo) Reptiles and birds are sensitive to fumes and absorb toxins, both chemical and plant, through their skin. My parrots in particular are easily effected by exposure to the wrong thing. I will also take this question to my parrot groups on Facebook. Thanks!

    • Karin, we have 5 parrots, a dog, a cat, a hedgehog, and a bearded dragon lizard. No problems. I won’t use anything but SAL Suds and Poop-Off around the birds.

  10. Hi Lisa,

    I’m a house cleaner and have been using Sal Suds for years and loving it. Somebody asked me yesterday about using it on marble floors. I checked your list above and don’t see that listed. I think the issue is with acid cleaners and I know Sal Suds is mildly alkaline. But can you tell me about using it on marble floors? Thanks.

  11. Hi Lisa,

    Can you add a Sal Suds soft scrub recipe to your cheat sheet? (And maybe one for the castile soap cheat sheet as well?)

    Also, since Sal Suds is a detergent, not a soap, does that mean it is harsher, and I should possibly be wearing gloves when using it (esp when mixing it, since I may touch the concentrated formula?) I don’t quite understand the difference between soap and detergent yet… If soap is safer than detergent, and Sal Suds is a detergent, how does Sal Suds fit into the category of non-toxic DIY cleaning supplies? Are things like Dawn and Palmolive detergents too (even though I think of them as soap)?

    Thanks!

  12. Can I use diluted Sal Suds on my carpets without rinsing? My carpet cleaner doesn’t have a tank for rinse water. Thanks!

  13. Lisa, I am curious as to whether or not Dr. bronners Castile soaps (peppermint, tea tree, etc.) will work as effectively at home cleaning as Sal Suds? I am highly allergic to Sodium Lauryl Sulfate which is the second ingredient in Sal Suds, so I wanted to just use the liquid Castile soaps for everything including laundry and floors… Please let me know if this will work?
    Thanks
    Veronica

  14. Hi Lisa,

    Is the Sal Suds safe for use to clean baby (newborn/infant) toys/play mats/activity gym etc? Baby is pretty much licking everything. Is the cleaner non-toxic?

    Thanks

  15. Just a note to let you know the many reasons I love Bronner’s products. I swim 4-5 days a week. I do a mile a day in the pool. I wear goggles, caps and earplugs and Sal suds has really helped me out. 1st I use it in my laundry, one of those measuring cups from drink mixes for one really large load in cold water, I add 1/2 cup white vinegar in the last rinse. We have very hard water, with iron, it stains everything, but so far,(over a year) so good. 2nd I use Sal Suds for my dish washing and general cleaning. I add 1/2 tsp Sal suds and 4oz vinegar to a spray bottle , I pour water in slowly from a pitcher and add a couple of drops of tea tree oil. I spray my dishes, fill sink with hot water, let soak a bit, drain sink, wipe dishes and rinse under hot water, using a machine, I just spray dishes and put vinegar in rinse cup. 3rd, for the swimming, every day in the shower I scrub my cap with a couple of drops of sal suds, then rinse, next I use a defoliating wash cloth and scrub the inside of my goggles with sal suds (our eyes sweat too, and dead skin….ugh) then the outsides and rinse well. I keep them in my locker wrapped in a towel, I do not dry them, been wearing them for over a year. The ear plugs I use are silicone disposables. I use each pair a week and toss them on Friday. As for the cap and goggles I wash them in my hand every day with a couple of drops of sal suds then rinse really well. I roll them up squirt them with a 50/50 mix of alcohol and white vinegar. I have very sensitive skin and most things annoy me, I am sensitive to chlorine. I use the peppermint castile for everything else, including my hair. Bronner’s really is a great product. I use 2 gallons of Sal Suds a year and and a gallon of peppermint lasst me for 2+ years.

  16. Hello Lisa!

    I always enjoy your blog. My question has to do with windshield wiper fluid. This truck I just bought calls for Optikleen concentrated fluid that you mix with distilled water. It’s GM recommended. I guess it’s been around for quite sometime but I have never heard of it. I caught a post in a forum where they mentioned what the ingredients were and said you could make your own rather than pay there steep price that it was made up of alcohol, distilled water and a surfactant. Sal’s Suds came to mind as the surfactant when I seen this. What do you think? Do you know anyone that has done this? Thanks for you in put always.

    Sincerely,

    Brenda Frank

  17. Can you use vinegar with sal suds? I know you don’t with regular castile soap(good article by the way!!!)

  18. lisa –
    I have extremely oily skin/hair and I tend to sweat a lot. As a result, most soaps and body washes do not get me adequately clean. One day I tried sal suds; it worked like a charm, and I have been using it as a body wash ever since. besides the claims that it can dry skin out, is there any reason that I should be wary of using it daily as a body wash/shampoo?

    thanks.

  19. Well, this started off promising but then no one was answered. Kinda boring and frustrating reading a bunch of unanswered questions. I’m disappointed and expected more from this company. All it does is make me wonder why she (Lisa) didn’t want to answer some of these questions.??? Hopefully she’ll get around to it soon. Until she does I’m on hold with my order. Sorry, but some of the questions asked are important to me.

  20. Hello! Does this have a neutral pH? We have Piedrafina countertops in our bathrooms and they recommend a neutral pH cleaner for them. Would this be ok on them?
    Thank you!

  21. Hi Lisa, I have a lot of questions as well as those above that are from 2014. How can I find your replies to these? Have they answered aomewhere else? I am excited about your product and want to start ridding of my toxic cleaners. Thanks, Cindy

  22. Can you tell me exactly what you use to clean makeup brushes? I have both Sal Suds and Castile Soap but not sure which to use and what else to mix how much with. THANK YOU!!

  23. I don’t know if anyone else has shared this, but I wanted to share that I’ve had success with thickening the Sal Suds for use in a dishwand. I put measured our 1/4 cup sal suds into my pyrex. Then I added 1/8 tsp salt. I mixed this together with a fork until it formed a thick gel. Then I added around 1/4 cup cold water. (I would measure it out and slowly add the water, whisking with a fork until you reach the desired consistency.) It seems rather flexible though, as I added too much water at first, which I correct with a bit more sal suds and a dash of salt. So far it seems good, though I’m keeping an eye on it for separation or hardening. But so far, so good. Just thought I’d share since I’ve seen others ask about it before.

  24. Can vinegar be used with Sal Suds? I know you have posted that it should not be used with Castile Soap as they neutralize each other but can I use vinegar in a recipe WITH Sal Suds instead of as a second step?

  25. I was wondering about using the Sal Suds in my dishwasher. I use it for laundry and now want to try in the dishwasher because it does so great with everything else. Does anyone have a recipe? I saw a link above, but it is no longer active. Thanks!

    • Hi Sarah – Yes! It does an excellent job of it.

    • Hello Sarah! I don’t know or can’t claim the Dr. Bronner’s kills germs or bacteria but I know that it cleans these things away. Since changing from store bought home cleaners, and using Dr. Bronner’s soap and water, my family’s health / immune system is no longer or as much compromised. Before switching, I was always at the Dr.s offices because my family was sick with something. It’s now very rare that my family becomes ill, and it’s usually only due to new surroundings, such as when my children went out of town to go to college. The secret to Dr. Bronner’s, is simply to use it. I clean my whole home with it. Hope this helps to answer your question. Have a great day!

    • Hi Penny – We don’t recommend it. However, you will find other customers who have found success in various formulas using the Sal Suds. We have also heard and experienced stories of bubbles pouring out around the sides of the washer, though, and general dishwasher unhappiness. It’s on our “to-do” list to figure out one of these days. In the meantime, definitely use Sal Suds for all your handwashing dishes.

  26. I like cleaning my make up brushes with woolite laundry detergent but the ingredients are harsh and I want to use an all natural detergent. Any tips on using this for make up brushes??

  27. Hi. I used sal suds in spray bottle hi strength on ants in the house and accidentally inhaled it. Is it toxic or are there any bad effects
    thank you

    • I’m not the expert but I think you don’t need to worry about toxicity or bad effects – that’s why you chose Dr Bronner’s! Good for you! I hope Lisa will soon have time to confirm here.

  28. Hi Lisa, We are starting to go greener and I am so excited… can you tell me how to make hand soap for the bathroom? I wondered if the lavender castille soap, diluted would work? Can you give me an idea of how to make it? I am definitely going to try Sal Suds too!

    • Hi Ann, I’ve been using Dr. Bronner’s castile soaps for years for household cleaning and disinfecting, face/body wash, shampoo and of course hand soap! I’ve used peppermint, lavender, and tea tree but they’re all great to use. The great thing about using these soaps for a hand soap is that you don’t need specific measurements. I use about 1/3 to 1/2 castile soap and 2/3 to 1/2 water respectively but you can always use more or less depending on your preference. Because it’s not a very viscous fluid it easily runs off of one’s hands when washing. Most people will put soap on their hands and proceed to rub their hands together under the water. With castile soap it’s best to first wet your hands then pump the soap on and rub your hands together and wash, and then run under the water. I’ve had people ask me if I’d put water in my soap dispenser and I had to explain I had castile soap in it. If you put the soap on your hands and then put your hands under running water the soap will just rinse right off. If you use it as I described you’ll find it creates a great lather. In fact, if you use increase the soap to water ratio a bit it makes a fantastic, luxurious lather for shaving. You’ll find Dr. Bronner’s is great for just about anything. They’re great products to experiment with! I’m actually going to make my first batch of home made laundry detergent using Sal Suds using Lisa Bronner’s recipe/directions. Happy green cleaning!

    • A foaming pump makes the most awesome hand soap with the regular castile soap. Thinning the soap is important. Here is how I do it. I filter and boil my water first. You can also use distilled water. I put a teaspoon of oil in the bottle first for moisturizing, but not necessary. I used sweet almond oil. You use one part soap to 4-5 parts water. For 12 ounces, this means 10 oz of water and 2 oz of soap. Pour warm water in the bottle first and then add the soap. This way you don’t get a lot of bubbles. I am currently using the Almond liquid soap. I plan to order the Baby unscented version and add the scents or oils I want. I love tea tree oil. This is so economical. A 32 oz bottle of soap should last a very long time. I bought a foaming soap dispenser at Walmart, but my favorites came from TJ Max by InterDesgn for $6.99 and they are glass. My plan is to order the Sal Suds to make my own dish soap, and multipurpose cleaner.

  29. In having a hard time with my Sal Suds on countertops. I have diluted it as you instructed, perhaps even more, and it is so bubbly and soapy. It leaves soap all over my counters which makes streaks, and then I have to rinse thoroughly with water. I’m at the point where I’m using about 1/4 teaspoon in a quart and this is still happening…

  30. New to Dr. Bronner’s and am loving it. Do I need to use fabric softener with Sal Suds and is it okay to use on a wood floor?

    • Hi Jeri, you don’t need to use fabric softener with Sal Suds or when using any other type of laundry detergent. I haven’t used it in over 20 years and my clothes come out soft and fluffy and I haven’t had problems with static cling. With fabric softener I found it left a residue on my clothes and it prevented my towels from absorbing water as well as they should. By eliminating fabric softener you’ll save money and you’ll help the planet by creating less waste. : ) If you should have a problem with static cling you can wad up some tin foil and put it in the clothes dryer. I know it sounds crazy but Google it. It actually works! If you used scented fabric softener and liked how it scented your clothes you could always buy some essential oils, put a few drops on a cotton round/ball and throw it into the dryer with your clothes. As for your wood floors, Sal Suds works great on sealed wood floors. If your floors are unsealed, you might want to wait for Lisa to answer that. Happy cleaning!

    • Jeri, I use sal suds on my wooden floors. I have a shark duo and so I fill up the water bottle first and depending how dirty my labs have made the floors with their muddy paws and drool I either use one or two drops of sal suds, added AFTER I have filled the bottle with water (don’t add first it gets very bubbly) and my floors come up great. I always use the buffing pad after I’ve washed them and it comes up nice and shiny. I cannot tell you about the laundry as have not tried that yet. Just remember though with sal suds that you don’t need much at all, it’s very good at what it does with just a drop, too much and you will have a house full of bubbles.

  31. Hi!
    The use in laundry is instead of detergent (like say Gain) or as a laundry detergent booster in addition to detergent?
    Thanks!

    • Sal Suds works instead of another laundry detergent. If you need a booster, try the baking soda or vinegar options.

  32. Hi,

    I am looking for a cleaning solution for cloth diapers and cloth inserts,. Will this soap work for that and if so exactly how do I use it? If so, can i use it handwash then user the dryer?

    • Yes! But machine drying misses out on the excellent whitening power of the sun, when there is sun! Since Sal Suds is so effective and clean rinsing, it makes a great option for cloth diapers.

    • I am interested in the measurements for using the Sal Suds for cloth diaper laundering. Would it be the same as the laundry dilutions above? Does the vinegar and baking soda still apply?
      Thanks

    • Hi Britt – I did not use cloth diapers, but if I did, I’d up the amount of Sal Suds to 4 Tablespoons ( 1/4 cup) and keep the vinegar and Baking soda. Let them dry in the sun, if you live where winter is sunny since the sun has great bleaching and deodorizing powers. Otherwise, a dryer is fine.

  33. I don’t recall having read anything about using Sal Suds to clean your oven before, but for me cleaning the oven holds the title of ‘worst job’ and I hate having to use those really harsh and pungent smelling cleaners which you have to leave on for hours and ensure you don’t end up burning your skin. After a friends mom put her oven on self clean and ending up with a kitchen full of firemen I decided, however tempting that sounded, I would avoid that option. Today I decided to give it a go with a drop of Sal Suds on a scrubbing sponge and I have to say my oven came up spotless. Now my oven is not overly dirty because I have to have a clean oven, but it cut through the usual spills and grease with ease and once cleaned with Sal Suds, I wiped it over with a magic sponge and it was all done in less than 10 minutes, totally clean. I have never known one product to be so versatile and it makes a nice change to just have one product in the cupboard instead of 5 or 6.

    • Fantastic, Mirry! Oven cleaning is definitely one of those tasks I avoid as well. I need to post about this, but another trick to help with really stubborn grime is to put a bowl of vinegar water (half and half) in the oven and bake it at 450 for 30 minutes and then turn it off but leave it closed for another hour or so. It will really have loosened what’s baked on the oven.

  34. Can I use Sam’s Suds our the castile soap in the dishwasher? This is literally the last of the chemicals I need to expunge from my household!

  35. I am a newbie and would like to know if Sal Suds would be safe and effective to use for cleaning soft vinyl windows? We have a screened in porch with soft vinyl windows that get filthy with dirt and water spots. We have tried cleaning with mild detergent and water to avoid any damage to the vinyl, but not only does it take forever to clean, it also leaves dirt behind. Any advice?

  36. I have read Roseanna’s comment from November 11, 2015, where she said castile soap is thin and hard to use as hand pump soap.
    Cindy on January 19, 2016, suggests using a foaming pump bottle and diluting the castile soap with water.

    I do not question either suggestion and am happy to find their comments and instructions.
    I am confused after reading both.
    Could someone explain, please.

    I have plain Bronner’s Castile. If I find it too drying, what can be added? I read almond oil. Could coconut oil (thick or fractionated) be used? Aloe Vera?

    Thank you.

    • Hi Christine – Dr. Bronner’s Castile does not work well in regular pump dispensers. As Roseanna says, it is too thin, and also, it will dry inside the pump and clog it. Instead, I recommend Cindy’s suggestion to use a foaming pump dispenser. Try a dilution of 1 part soap to 3 parts water. Adding oil directly to the soap will only bind up the soap because the soap will attach to the oil. Better to use a follow-up moisturizer. Bronner’s Lavender Coconut lotion is a light lotion for regular use.

    • Hi
      I’ve read on several blogs the use of oil (like vegetable glycerin) helps preserve the soap. Can I just use soap and water then?

    • Soap and water is all you need in the foaming pumps. Adding oil or glycerin would not help preserve the soap. The soap already has a preservative in it – tocopherols (vitamin E).
