Sal Suds Dilution Cheat Sheet

Sal Suds - Dr. Bronner's product

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 Biodegradable Cleaner 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.

All this to say, I use Sal Suds A LOT! In fact, it might be more efficient to list what I don’t wash with it. 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.


Dishes (Handwashing): ½ – 1 ½ tsp. (2.5 mL to 7.5 mL) Sal Suds in a large sink of water. Or 1 drop Sal Suds for one pot, more if needed.

  • So I don’t use too much, I keep a bottle of diluted Sal Suds by my sink: ½ c. (120 mL) of Sal Suds in a quart (1 L) of water. A small squirt in a pot or a larger squirt for a sink.
  • With All-Purpose Spray: Using a Sal Suds Spray to Clean Dishes

Laundry: 1 to 1 ½ Tbsp (15 to 22 mL) for a large load in a top loading washer. Optional: For extra whitening/brightening, add ½ c. (120 mL) baking soda to wash cycle and/or 1c. (240 mL) vinegar to rinse cycle. Double these amounts for standard (non-HE) washers.

Pretreating Laundry Stains: Pre-measure Sal Suds for load. Apply some or all directly to stain(s). Let sit 30 minutes or more. Add remaining Sal Suds to washer. For broad stain, spray with a solution of half Sal Suds/half water.

Handwashing Delicates: ½ capful (½ Tbsp. or 7.5 mL) Sal Suds in about 1 gallon (4 L) of water. Swish gently. Let soak 10 minutes. Swish again. Rinse with clean water. Gently press out excess water with a towel. Hang clothing or lay flat to dry.

Mopping (Wood, Laminate, Vinyl, Stone & Tile): 1 tsp. (5 mL) Sal Suds in 1 gallon (4 L) of hot water. Dunk mop (microfiber, preferably) and wring thoroughly. On wood and laminate, avoid excess water and mop up wet areas.

All-Purpose Cleaning Spray: 1 Tbsp. (15 mL) Sal Suds in a quart (1 L) of water. Hint: Put water in the bottle first. Spray and wipe with a damp cloth. Optional: Add ¼ tsp. (1.25 mL) tea tree essential oil. Use on any surface that is safe in contact with water.

Window Wash: (aka Sal Suds Lite) ½ tsp. (2.5 mL) in a quart (1 L) of water. Spray and squeegee. Follow with a spray of pure club soda, or half vinegar/half water, and squeegee.

Stainless Steel Appliances & Sink: Spray appliance with All-Purpose Spray. Wipe with a soft damp cloth in the direction of the grain. Spray sink and sprinkle with baking soda from a shaker. Scrub then rinse.

Toilets: For best results, empty toilet. Spray bowl thoroughly with All-Purpose Spray, or sprinkle 2-3 drops of Sal Suds directly on toilet brush. Sprinkle baking soda on a brush, scrub bowl. Let sit 10 minutes. Turn water on. Flush.

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

Oral Appliances & CPAPs: Removable retainers, nightguards, etc. & dentures: Wet device. Add 1-2 drops of soap to a soft toothbrush. Brush gently, then rinse. CPAP mask, tubing, and headgear: Submerge in a warm water with a small squirt. Allow to sit 30 minutes, then wash, rinse, and towel dry. Allow to air dry thoroughly before reassembling.

Pressure Washer/Carpet Cleaner: In cleaning solution chamber, fill with water and add 1 drop of Sal Suds. Add 1c. (240 mL) vinegar to rinse water (optional). Use All-Purpose Spray on carpet spots (use sparingly).

Upholstery: Spray a wet (not dripping) cloth lightly with All-Purpose Spray. Gently rub cloth on the spot. Rinse area with a second wet cloth. Blot with a dry cloth to extract moisture. For large areas, use a carpet cleaner (above). Always spot test first.

Cars: ½ Tbsp. (7.5 mL) Sal Suds in 3 gallons (12 L) of water for exterior. Use All-Purpose Spray on interior surfaces and leather seats. Wipe with damp cloth.

Patio Furniture: ½ Tbsp. (7.5 mL) Sal Suds in a bucket of warm water. Wash with sponge, microfiber cloth or stiff brush. Wipe with damp cloth.

Bonnie says:

I’m ashamed to say I use the Dawn & vinegar recipe to clean my shower
where you just spray, let sit awhile and then rinse with hot water.
I want to just use Sal Suds like I do for everything else including laundry.
What’s your method?

Lisa Bronner says:

Hi Bonnie- No shame here. We’re all on a journey! Even with our cleaning practices. Regarding the shower cleaner, Sal Suds cannot be used to replace the Dawn in this combo because vinegar makes Sal Suds less effective. Unfortunately, there isn’t a “spray and go” method that works quite the same. However, if you have a durable type of shower material (i.e. not a soft stone like marble or travertine), you can do a daily spray of vinegar & water (half and half) and rinse that with hot water. For weekly cleaning, I use the Sal Suds All-Purpose Spray, made with 1 Tbsp. Sal Suds in a quart of water. I spray the walls, scrub with a brush, and rinse down.

Joanna L Mix says:

I made my Sal suds homemade dish soap for handwashing dishes. The foam bubbles do not last. Can you tell me why?

Lisa Bronner says:

Hi Joanna- Do you have anything in your dishwashing solution other than Sal Suds and water? While bubbles are not a correlate to cleaning, Sal Suds is known for its bubbles, so I’m wondering if either there’s another ingredient interfering or perhaps your solution is too diluted. Extremely hard water can also reduce bubbling.

Amy says:

One of my employees left a bottle in the car and it froze. Am I still able to use it?

Lisa Bronner says:

Hi Amy- That’s not a problem. Sal Suds has a freezing point in the 60’s, due to the coconut oil source of the ingredients. When it freezes, it turns white and thickens up, eventually turning solid. This does not harm the Sal Suds, and once it warms up, it becomes clear and liquid again. It is still safe and effective.

rachelle kazenbroot says:

Hi Lisa

Could I use sals suds to get quite thick lichen and mold off a terracotta tiled roof?
The roof cleaners use such toxic chemicals so Id like to give them sals instead.

Thank you

Lisa Bronner says:

Hi Rachelle- While I’ve never tried this, I think it should work. Are you thinking in a pressure washer? If so, try just 1 drop of Sal Suds mixed with water in the cleaning solution compartment.

Mohammad says:

I am trying to look for pH of undiluted sal suds cleaner for business reasons… if you can provide that

appreciate your efforts
Mohammad S.

Lisa Bronner says:

Hi Mohammad- The pH of Sal Suds is 6.5 – 7.0.

Kim says:

I just learned about Sal Suds and it looks like it might be exactly what I’m looking for in a non toxic cleaning product. I had a couple questions: 1) Can you use it to clean stainless steel pans? I’m assuming it would be okay if you can use it to clean stainless steel appliances. 2) I saw that it is safe for granite. For food contact areas like kitchen countertops, do you have to rinse with water after cleaning?

Lisa Bronner says:

Hi Kim- I’m hardly biased, but I’m a big fan of Sal Suds! Sal Suds is safe to use on stainless steel pans, as well as cast iron. Use one drop per pot or pan – a bit more if needed. Because Sal Suds is exceedingly clean rinsing, after spraying the All-Purpose Spray on countertops and other surfaces, simply wipe with a damp cloth.

Steve says:

I’m using Sal suds in a front loading HE washer. I’m using about a tablespoon as directed with about a quarter cup of baking soda. I’m not getting any suds. It appears that the washer is just washing with water. Clothes don’t smell that clean. Using more suds doesn’t seem to work much either. I can see much more suds in the washer when using a commercial detergent. I’m about ready to give up on it, but figured I’d reach out for a possible explanation/solution. Thanks

Lisa Bronner says:

HI Steve- Thanks for reaching out on this. Are there any other additions to the load besides Sal Suds and baking soda?
