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 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.

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.


Laundry: 2-3 Tbsp. (30-45 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 1 c. (240 mL) vinegar to rinse cycle. Halve these amounts for 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 lighter stains, spray with All-Purpose Spray (below).

Handwashing Delicates: 1/2 capful 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.

All-Purpose Spray: 1 Tbsp. (15 mL) Sal Suds in a quart (1 L) of water. Hint: Put water in the bottle first. Optional: For extra antimicrobial punch, add 1/4 tsp. (1.25 mL) tea tree essential oil. Use on any surface that is safe in contact with water.

Stainless Steel Sink: Spray sink with All-Purpose Spray and sprinkle with baking soda from a shaker. Scrub then rinse.

Toilets: For best results, empty toilet. Spray bowl thoroughly with All-Purpose Spray, sprinkle baking soda on the brush, scrub bowl, let sit 10 minutes, turn water on, flush.

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

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.

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

Dishes (Handwashing): 1/2 – 1 1/2 tsp. (2.5 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: 1/2 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 Sal Suds to Clean Dishes

Mopping (Wood, Laminate, Vinyl & Stone Flooring): ½ Tbsp. (7.5 mL) Sal Suds in approximately 3 gallons (12 L) of hot water. 20 drops tea tree oil (optional). Dunk mop (microfiber, preferably) and wring thoroughly. On wood and laminate, avoid excess water and mop up wet areas.

Cars: ½ Tbsp. (7.g 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: 1/2 Tbsp. (7.5 mL) Sal Suds in a bucket of warm water. Wash with sponge, microfiber cloth or stiff brush. Wipe with damp cloth.

Wondering if Sal Suds is safe to use to wash down jackets or sleeping bags with verses a specific down wash detergent. Thanks!

Lisa says:

Hi Lisa. I am having trouble with my dilutions.

I am using sal suds for an all purpose spray and feel like my dilutions are off for this. I broke it down from your dilutions above for a 16oz bottle but I think I still have it wrong. Should I being using distilled water with this?

Also, I use castile soap for hand wash but there are always little films floating within. I always mix this with distilled water, as I know castile soap reacts with hard water. Am I adding too much castile soap? I am using a 16oz bottle for this as well.

What are your suggestions for dilutions for both of these in 16oz. bottles? What is the shelf life for both once mixed also?

Thanks for your time. Love your products 🙂

Lisa Bronner says:

Hi Lisa- It’s great to hear our products work well for you! A 16oz bottle of Sal Suds All-Purpose Spray would use 1/2 Tbsp (or 1.5 tsp.) Sal Suds. Regular tap water is just fine with Sal Suds as it doesn’t react with the minerals present in hard water in the same way Castile Soap does. I’ve never had a bottle of this solution go bad, but generally use within two or three months.

The dilution for a foaming hand soap dispenser with Castile Soap is 1 part soap to 3 parts water – or roughly 5oz soap and 10oz water in a 16oz dispenser. If this seems too concentrated, dilute further to 4oz soap and 12oz water. Many customers prefer to use distilled water because it makes for a clearer solution with the Castile Soap. When using water with any hardness, you will see the cloudy, though harmless, precipitate in the solution. For shelf life, follow your nose – if it is smelling off, then dump and remake. If you find you don’t go through it fast enough, mix-up a smaller batch.

Lisa Bronner says:

Hi Frances- The Sal Suds is not designed for automatic dishwashers, and I have not had success in my personal experiments with it as such. In general, it foams too much for the way the machines work. With my hard water, I also found a film on my glassware. However, I also know that many of my readers have used it successfully as such.

Tania says:

Hi Lisa,

I love Dr. Bronner’s castile soap and sal suds! I have used castile soap for years and make our foaming hand soap with it. I discovered Sal Suds through Grove Collaborative and have decreased the amount of cleaning solutions I use around the house. I know that once diluted Sal Suds all-purpose spray is good for a couple of months. What is the shelf-life of the undiluted Sal Suds once I open the bottle?

Lisa Bronner says:

Hi Tania- It’s great to hear our products are working so well for you! Sal Suds has a guaranteed shelf life of 24 months once opened. There’s actually a symbol on our labels, and others’ on the market, that looks like an open jar with a number in it. This indicates the product’s shelf life once the product is opened. (I have to admit, it wasn’t that long ago that I learned this little nugget!) says:


I have another question, since vinegar can be combined with sal suds is it possible to use citric acid instead?

Lisa Bronner says:

Hi Yameirae– I haven’t tried doing this, but thinking theoretically, you should be able to swap citric acid for vinegar. I looked this up in the book Putting Food By. To get the 5% dilution common to most household vinegar, you would need to dissolve 2 Tbsp. fine citric acid in 2 cups of water. Then follow the dilutions for vinegar.
