Dilutions Cheat Sheet for Dr. Bronner’s Castile Soap

Download PDF Document

Dilute! Dilute! OK!* But how much? Here is a quick reference. None of this is a hard and fast rule. If your stuff is really dirty or your water is really hard, then you may want to use more than the recommended amount. However, this should get you started. You’ll notice that for some applications, I recommend pre-diluting the soap – combining the soap with water in a container. For other applications, the soap is diluted by the water present in the situation. It’s a matter of personal preference. Keep in mind that if you predilute, you are also diluting the preservative (tocopherols – vitamin E), so the shelf life drops. Use within a couple weeks. And yes, there are 18 uses here. Dr. Bronner's Castile Liquid Soaps

* Long time Dr. Bronner’s users will remember this expression from the old labels.

Body Uses:

Face: 2-3 drops on wet hands, applied to wet face

Body: one small squirt on a wet washcloth, applied to a wet body

Hair: ½ Tbsp. in your hand, worked into wet hair, or dilute ½ Tbsp. in ½ a cup of water and work that into wet hair

Bath: Completely depends upon water amount, but roughly 2 Tbsp. soap in an average sized tub. (Doesn’t bubble, but still cleans)

Shaving: Face – 10 drops; Underarms – 3 drops; Legs – ½ tsp; Work to a lather in wet hands and then apply to area.

Teeth: 1 drop on a toothbrush. (Yes, it tastes like soap.)

Foot Bath: 1 ½ tsp. in a small tub of hot water.

Clearing Congestion: 1 Tbsp. in a bowl of steamy hot water. Breathe in mist with a towel draped over the head.

Household uses:

Dishes (handwashing): Pre-dilute 1:10 with water. Squirt on a scrub brush and scrub dishes.

Laundry: 1/3-1/2 c. of soap for a large load in a normal washer. Add ½ c. vinegar to the rinse cycle. Use half of these amounts for HE

Mopping: ½ c. of soap in 3 gallons of hot water

All-purpose cleaning: ¼ c. soap in a quart of water in a spray bottle. Add ¼ tsp. tea tree essential oil if desired.

Windows: 1 Tbsp. soap in a quart of water in a spray bottle. Follow up with pure club soda, or half vinegar/ half water.

Toilet: Predilute 1:4 with water in a squirt bottle. Add ¼ tsp. tea tree oil. Empty toilet, squirt bowl thoroughly, sprinkle baking soda on the brush, scrub bowl, let sit 10 minutes, turn water on, flush.

Other Uses:

Fruit and Veggie Rinse: 1 dash (approx.. ¼ tsp.) in a bowl of water. Dunk produce and swish. Then rinse in clear water.

Dog washing: Amount varies widely depending on size, hair type and length, and overall dirtiness. I wet my dog thoroughly, then start to work in castile soap up and down their body until I have a good lather. Really massage it in down to the skin. Your dog will thank you for it.

Plant spray for bugs: 1 Tbsp. in a quart of water. Add ½ tsp. cayenne pepper or cinnamon, if desired.

Ant spray (not on plants): ¼ c. tea tree soap in a quart of water. (This concentration will burn plants.)

I’ve tried to keep this short and sweet. If you have any questions, please ask away!

  1. Hello I am just writing about the palm oil in products. Where are these sourced from I would like to buy your products but do not buy products that have palm oil from countries that destroy rainforest such as Indonesia. Also are your products tested on animals? I know people may think that I am just being fussy etc but I am very aware of the problems associated with animals and testing of products etc so I need to be aware of the products I buy. THANKS

  2. I dont know if this is the right space for this, but my ex-boyfriend (now best bud) swears that the peppermint and/ or lavender soap will help keep me from being eaten alive by mosquitos (and ticks). I am one of the lucky few who get huge welts from bug bites.
    I know I love the smell of both of these (and my pit bull love her tubby in the peppermint!) and am hoping this might help me in my quest for bug repellent that won’t poison my animals and myself..
    Thank you!

    • Hi Dawn – While Peppermint is a great natural deterrent to mosquitos, it might not be enough to keep them at bay if they are really swarming and are intent on eating you. It’s a great start, though, and couldn’t hurt. Long sleeves and pants are a good idea, and you might need something more. I’ve also found the peppermint castile to be very relieving to itchy bug bites afterwards.

    • Thank you♡ It is black flies (in the mornings and afternoons) and mosquitos (afternoons and evening) season here in Maine. ANYHING to help keep them away (even a little) is worth a try. PLUS my skin feels incredible♡

    • Hi Edward – The Tea Tree Castile in particular has been found helpful in clearing all sorts of skin conditions.

  3. I have used dr.bronners soap for even more uses than the ones listed. I have also used it to clean windows, car, bicycle, motorcycle and really anything that gets because there is nothing else i would rather use. I spend too much buying this soap but there is nothing better beside the story of Emmanuel.

  4. I have used Dr.bronners soap for even more uses than the ones listed. I have also used it to clean windows, car, bicycle, motorcycle and really anything that gets dirty because there is nothing else I would rather use. I spend too much buying this soap but there is nothing that makes me happier than having it with me at all times. We can all thank Emmanuel for this!

  5. Awesome thank you so much for this info!!! I am new to the Dr Bronners family and I love it already!!! I bought the large bottle of the baby magic castile soap and we love it.. In fact we all use it as a body wash, we feel squeaky clean after using it and I am so happy to get rid of so many chemicals in our household!

  6. All good and all appreciated. Glad I found your products again.

  7. If you use this as a laundry detergent do you have also use vinegar

    • Hi Tiffany – For laundry, the Castile works great. Vinegar is useful as a fabric softener. Add it to the rinse water, or the fabric softener compartment. You don’t want the vinegar to mix with the castile. I use about 1 cup of vinegar for a large load.

  8. Thank you! I was thinking I would put it in a pump bottle. But I think just a small bottle full strength in the shower might be ok.

    • I honestly just keep a small bottle in my shower and use it full strength on my body loofa. It is the best soap and mainly the only soap for my body. I might be adding the tree soap for my hair.

  9. I’ve been using Dr. Bronner’s organic shikakai soap, but it is so expensive and we go through a real lot of it. Is there any way to slightly dilute the regular castile soap and use in a foaming soap dispenser without it getting clogged? You indicate to use drops for various uses, but how do you pour a couple drops from such a large bottle? Thanks so much for the help!

    • Hi Margie – For a foaming pump, use a ratio of 1 part castile to 3 parts water. This works really well.

    • Just to Add to Lisa’s ratio is that if it sits for a couple days, you might have to just give it a little shake to remix it. I actually have done this for my brother who I stay with when visiting from out of state, and he likes this a lot. Now to get the rest of their foam pumps converted is my new mission.

  10. Hi Lisa,
    I have a question in regards to using castile soap to brush my teeth.
    I tried it for the first time yesterday. My teeth look and feel great, I even think it’s better for removing plaque than my normal toothpaste cause my teeth felt cleaner than they have in a long time.
    I’ve always heard that I need a toothpaste with flour to protect my teeth from cavity and decay. Will the castile soap also protect my teeth from cavity and decay? Is there a difference of protection to what sent you use? I used the non sent baby mild one.

    • Hi Lena – There would not be a difference from scent to scent in their ability to clean the teeth. The soaps have been great through the years for teeth brushing, but we did release a line of toothpastes two years ago that do contain coconut flour, if that’s what you had heard about regarding the flour. I am thinking that perhaps you got auto-corrected and meant flouride, though. Neither our toothpastes nor our soaps contain flouride, and they do a great job of keeping teeth healthy and decay-free.

  11. We are traveling and need to take something with us to wash laundry if needed. Why do you suggest using vinegar in rinse water? I don’t think TFA will clear that :). Thanks!

    • Hi Mary – Vinegar acts as a rinse aid and fabric softener. It’s really only needed if the water is particularly hard. You can probably do without it, but if you’re concerned, take the Sal Suds along instead. It is clean rinsing even in the hardest of water.

  12. For dish soap, I followed the dilution recipe however, there are no suds, it doesn’t soap up at all. Any advice or is that just how it is?

    • Hi Natalie – Since there aren’t any synthetic foaming agents, the Castile doesn’t produce the copious bubbles of a conventional detergent. As much as we’ve been trained to think otherwise, bubbles aren’t a sign of cleaning power. The dilution definitely still cleans, though. If you’re washing really greasy stuff, you might need to up the concentration.

  13. Hi Lisa

    Could u kindly out of experience provide a decent dilution for face wash. Something that foams well. How many cups of water to how many cups of the castle soap?

    • Hi Jerry – To make a nice foaming face wash, use a foaming pump dispenser at a ratio of 1 part soap to 3 parts water. I recommend the Tea Tree Castile for the face.

  14. Lisa, how much would you suggest diluting Dr. Bronner’s liquid soap when using a foam pump dispenser? I have a few that came with another good quality (no chemicals) liquid soap, and they are wonderful, but the Dr. Bronner’s does have to be diluted. Is 25% liquid soap to 75% water too dilute?

    If you want to use the Dr. Bronner’s liquid soap for dishes, how much would you dilute it if you want to squirt it into a dishpan of water?

    I think that is all the questions I have for now! Thank you!!!

    • Hi Rhonda – the 25%/75% dilution you mention is perfect for foaming pumps. For dish soap, it entirely depends as you might expect on the volume of water in the sink, But I’d do a couple good squirts. For me, I usually squirt the soap on the dish cloth and wash away so that I can keep the amount down and the soap gets where I want it to. Whatever works best for you!

  15. Diluted this to wash dishes, it foamed up straight away but then fizzled away, doesn’t seem to cut through grease, using lemon.

    • Hi Emma – I find that it works best to use the dilution in a bottle and squirt directly on dishes, rather than to make a sinkful of suds. For super greasy stuff, feel free to increase the concentration. Also, don’t mix lemon juice with the soap. Lemon juice (and vinegar) react with the soap and break it down. You can read more about that reaction here: http://www.lisabronner.com/a-word-of-caution-about-vinegar-and-castile-soap/

    • Hi Lisa, I meant I had the lemon scented one, not I put lemon juice with it 🙂
      I will give the spritzing a go, thanks for the tip, it’s working fab as a hand cleanser though. Woohoo!

  16. Can I use a foaming soap dispenser to dispense a shampoo dilution? If yes, would I use the same 1/3 cup soap per cup of water as I would for a hand soap in a foam dispenser?

    Thanks!!
    Tanya

    • Hi Tanya – Start with that dilution and feel free to adjust it to your liking.

  17. I have always had difficult skin and no time or money to chase the answers or remedies. Finally found a dermatologist that can put my eczema/psoriasis to sleep with strong medications but tough skin remains. I and many who know me have purchased so many products that might appear promosing but within 10 days I’m back to square 1. I use Cal-Ben Liquid to hand wash dishes. It is the only thing I am consistently willing to purchase because I know what the results will be. Please tell me what program/products you would suggest.

    • Hi there – We have received very positive comments regarding our Unscented Baby Mild Castile soap and Tea Tree Castile soap from our customers with skin issues such as eczema, psoriasis, rosacea, and oily skin. Since I haven’t tackled either eczema or psoriasis myself, here are some responses from customers:

      • “I’ve had psoriasis for 10 or 11 years. I’ve used prescribed creams and ointments even tried over the counter stuff. They helped in their own way, but are loaded with who knows what. Recently, I switched form a Dove product to Dr. Bronner’s [castile] bar soaps and I’m so glad I did! I mostly use the hemp teatree. But, throw in the peppermint from time to time. Sometimes I even mix them! Haha! Thanks, guys! You make great stuff!”

      • “I have plaque psoriasis on my neck,scalp and ears. I have found that using your unscented baby castile soap is the best base for my diy shampoos and hand wash. Even the “natural”, “hypoallergenic” soaps make me flare up.”

      I would also recommend our new unscented Magic Balm for softening tough skin. https://shop.drbronner.com/organic-magic-balm

    • Hi Shelby – Yes, it is safe for wood floors. Dilute it as for mopping. Be sure the mop is not sopping, as it is water that will harm the floor.

  18. Hello Lisa!

    We love dr bronners soap. Trying not to buy plastic though. If I grate and melt my bar soap
    Do these conversions work?
    Thanks
    Amy

    • Hi Amy – We hear you on the plastic. We’ve given it a lot of thought ourselves, which we discuss in this article from our website: https://www.drbronner.com/about/our-earth/packaging-innovations/.

      The bar soap does not melt easily. I’ve tried this. However, you can try grating it into water and boiling it. It certainly won’t look like the bottled castile – it’ll be cloudy and when it cools it will become somewhat gelatenous. I haven’t tried using this in my formulations, though. And I am not sure of the amount of water. I realize this isn’t fully helpful, but maybe another reader will weigh in here who has done this.

  19. Is it safe to use Dr. Bronner’s Castile Soap to clean eyeglasses that have anti-reflective coatings? If so, what should the dilution ratio be? Thanks.

    • Hi Mark – I really don’t know. I wonder what’s in the solution they recommend? If it’s alcohol based, I would recommend using the Dr. Bronner’s hand sanitizer. If it’s a mild soap, then the Castile would be fantastic. Make a super diluted solution (actually putting it in one of our hand sanitizer bottles would be perfect) – maybe 1 tsp. per cup of water?

  20. where can i get a foaming dispenser to dispense my dish soap and hand soap? I have tried regular pumps and putting in the bottle ,but no foam and the pump gets clogged and soap squirts everywhere….

    • Hi Ellie – A couple options – either buy a foamer that already has something in it, which might be the least expensive way, or you can buy one empty. I’ve done it both ways. The empty ones I got online. They’re Cuisipro brand.

    • Thank you Lisa.

      I found this on Amazon last night:

      Cape Cod Importers
      Foaming Soap Dispensers Pump-Bottles for Dr. Bronner’s Castile Liquid Soap, 250ml (8.5 oz) – Pack of 3
      4.4 out of 5 stars 287 customer reviews | 19 answered questions
      #1 Best Seller in Bathroom Countertop Soap Dispensers.

      I thought I would try this… 🙂

  21. Have you tried making a soap using the citronella plant as a way to repel Mosquitoes? I love the smell and I feel sure it would work great as a new verity.

    • Hi Rita – We haven’t but that sounds very intriguing. I will share that with my brothers and see what we can do! Great idea!

  22. I have been using Dr. Bronners Hemp Almond castile soap for seven years now. I have a glass bottle, foam dispenser pump at my kitchen sink, bathroom sink, and in my shower. I use it head to toe with no problems ever.
    I drink distilled water and use it for mixing up my cleansers. I use Dr Bronner’s Sal Suds for hand washing dishes, mopping the floors, and general cleaning. If I run out, I will use the castile soap.
    Really appreciate the way it cleans and rinses so well. Great product.

    • Hi Leta – Great to hear! I’m glad you shared!

  23. I have a large bottle of the lavender castile liquid soap. How can I dilute it to make regular liquid hand soap?

    P.s. I miss the 18 uses printed on the bottle, instead of the 10 it lists now.

    • Hi Katie – Sounds like you’ve been a long time user if you remember some of our previous bottles! There is so much info required on there that some of the good stuff had to go. For hand soap, you can either use a couple drops straight out of the bottle, or dilute it in a foaming pump dispenser at a ratio of 1:3. The soap does not work well in a regular pump. It will clog it and shoot out sideways, but in a foamer it does well.

  24. Hey Lissa,
    Ive got scalp bulit up. At what proportion should i apply Dr Bronners castile soap.
    I already brought baby mild unsented castile soap

    • Hi Sachu – For hair, I really prefer not to pre-dilute, but rather to get my hair really wet and then sprinkle some drops straight out of the bottle. For my long hair, I end up using about 1/2 Tbsp. For super short hair, probably just 4 or 5 drops.

  25. I would like to replace my current detergent for fine washables with Dr. Bonner’s Castile soap. Do you have a recipe? Thanks.

    • Hi Nora – The Castile soap is great for delicates. Use one capful in a sink of water. Swish them around a let them soak for 10 minutes or so. Swish them some more and rinse well.

  26. I’m planning on making dish soap with essential oils. What ratio should I use for a 16oz storage bottle? I’ve tried researching dilution ratios & haven’t had any luck!

    • Hi Hannah – For a dishwashing soap for hand washing in a 16 oz. bottle, fill the bottle mostly with water and add 1 1/2 Tbsp. of Castile soap and 10 drops of essential oil. If this isn’t concentrated enough for you, feel free to add more soap to it.

  27. Hi Lisa!

    I see you have noted that the hair link you have listed that the products are not good for colored hair. Just wanted to be sure you are suggesting that no Dr. Bronners soaps/hair products are good to use on colored hair?

    Also, for the laundry- is Apple cider vinegar okay to use or do you suggest regular, white vinegar?

    • Hi Shawna – It is the soaps that are not good for colored hair – The Castile and the Sugar Soaps. These have an alkaline pH that cause the hair follicles, where the dye is stored, to open and leach out. The Hair Rinse and the Hair Cremes are fine for colored hair.

      For the laundry, ACV would be fine, but I normally opt for regular white for the cost.

  28. I have recently purchased a large bottle of the lavender castile soap for a homemade laundry detergent (which i love!) But my question is using this scent for more things…i’m reading a lot about hand soaps but what about a bath soap for my kids — how would I dilute it?

    • Hi Lindsay – For my kids in the bath, I didn’t predilute the soap since there is already so much water there. I just used a couple drops on a wet washcloth and scrubbed them down. Or you could add a good squirt directly to the bathwater. Not only would the aromatherapy be very soothing, but they would get clean by the soak. I still scrub them down with a cloth, though.

  29. Hi, I went by My organic store today and saw this! I bought the rose soap bar. I was wondering does the bar soap work as tooth paste to? Thanks!

    • Hi Ali – Yes, the bar soap will work as a toothpaste. You can just swipe your brush over it a couple of times. If you do want a more traditional toothpaste, we do have that as well. But if you’re traveling light, it’s great to have one soap that cleans it all.

  30. As a Dog Groomer for many yrs I love using Dr Bronners peppermint liquid soap to bathe
    mine & my clients dogs. I dilute it 16:1 and
    it really cleans their coats well. I follow up with a 2nd bath & then us a conditioner. My clients
    love how clean it gets them and how safe it
    is for the dogs & the environment.

    • Great to hear from a professional on this, Holly! Thank you for sharing.

  31. Can i use the unscented castile soap for teeth brushing for my 6 yrs old kid? I read that 1 drop for adults to brush teeth. What about for children? Really love the castile soap as face and body wash! Thanks.

    • Hi Cheryl – Yes, you can use the castile soap for brushing teeth, but it does taste like soap and your 6 year old may object. If so, consider the Dr. Bronner’s toothpaste (https://shop.drbronner.com/toothpaste) as an alternative. My kiddos like the Anise and Peppermint in particular.

  32. Hi Lisa,

    I am very interested in buying your Sal Suds soap to combine it with Neem Oil for my organic vegetable garden. I have seen a number of well known YouTube organic gardeners who recommend using 2 Tbsp Cold Pressed Neem oil and 2 Tbsp Sal Suds to 1 gallon of warm water to spray for pests in the vegetable garden. My one concern is the sodium laurel sulfates. I have a hard time thinking that it would be good to spray on our vegetables that we’re eating, and so I was wondering if the Castille soap would be better since it doesn’t contain any SLF’s. I have a son with severe Crohn’s disease, and I try to feed him foods that are as clean as humanly possible (not easy), but I also have an insect infestation that is decimating my garden so I need to do something now. Please let me know what your thoughts are on the matter. Thank you!!

    • Hi Melanie – I agree with you that the Castile soap would be a better option here and I don’t see any drawbacks to using it in this solution instead of the Sal Suds.

  33. Hi Lisa! How can I remove gum and taffy from a canvas backpack?? Thank you!

    • Hi Alyson – I’ve been there. Except it was silly putty. It’s now banned from my house. Rubbing alcohol is what you need. Alcohol works great to remove both gum and taffy. It loosens it fairly quickly and you’ll be able to scrap it off with a metal butter knife. I happened to use the Dr. Bronner’s hand sanitizer but normal rubbing alcohol is fine.

  34. I love your soap, have fond memories of first hearing of dr bronners peppermint soap in college in the 70’s, such a cooling experience when showering!
    For Tea tree oil, people need to be aware that tea tree oil, even in diluted forms, is quite toxic for cats

    • Hi Barb – It’s great to hear from such a long time customer! Yes, you are absolutely right. We only recommend our unscented Baby Mild for cats. They are much more sensitive to essential oils and with their grooming, they are more likely to ingest them.

  35. I would like to bring castile soap while traveling, so I have just a few questions. 1) How much should I use for hand washing clothes? 2) Is it ok to use the scented soaps, like lavender or rose, for brushing teeth? 3) Is it ok to combine different scents into one bottle (I have small amounts of each and it would be cheaper than buying a whole new one)? Thank you so much for answering these questions and for this great cheat sheet!

    • Hi Michela – It’s great for travelling. For handwashing clothes, it is dependent on the amount, type, and dirtiness of clothes, but let’s say you’re washing in a typical sink, which would hold about 2 gallons of water. I’d put in a couple capfuls of soap. Or, if we’re talking outdoors, I would wet the clothes well, then put a few drops of the soap directly on each item and then suds them up. It’s fine to use the scented soaps for teeth brushing, and it’s fine to combine scents. Some of my favorite combos are Citrus & Almond and Peppermint & Eucalyptus (very refreshing when camping!), but really there’s no problem with combining any or all. Happy trails!

  36. THANK YOU, THANK YOU, THANK YOU! I have just ordered a bottle of Dr. Bronner’s Pure-Castile Soap (peppermint) as I am converting to natural and healthy alternatives, and I want a house that is clean AND doesn’t smell like chemicals. And, after researching various DIY recipes, I realized that I want to keep things simple …. I don’t want to buy many different products and mix several different bottles. The Pure-Castile Stop and the Sal’s Suds come to my rescue! Now I can mix just a few bottles and use them according to your cheat sheet. Thank you again!
