How Much Laundry Soap Should I Be Using?

Posted on March 07 2018

The most popular question to hit my inbox is:

How much laundry soap SHOULD I be using?

Most people think they should use more soap to clean their loads of laundry, and that may be true when it comes to the synthetic/conventional detergents you may have used (or are currently using). Real soap works differently than detergents so more isn't better. 

Real soap relies on pH to do the work of cleaning. So depending on the type of washer you have, the type of water you have, and the type of laundry you are washing greatly depends on the amount of soap you should be using. 

For reference: 

1 tablespoon is equal to a 1/2 fluid ounce
2 fluid ounces is a 1/4 cup
4 fluid ounces is a 1/2 cup

If you have average water (meaning you have hard water but you have a water softener), and an HE washing machine you would use:
1/2 tablespoon of MamaSuds Laundry Soap for a load of bath towels
1/2 to 1 full tablespoon of soap for a regular clothing load
1 to 1.5 tablespoons for a dirty load (like sports gear or outside play clothes)
1.5 to 2 tablespoons for a load of cloth diapers (or equally dirty load)

If you have average water and a regular washing machine you would use:
1 tablespoon of MamaSuds Laundry Soap for a load of bath towels
1-2 tablespoons of soap for a regular clothing load
2-3 tablespoons or a dirty load (like sports gear or outside play clothes)
1/4 to 1/2 cup for a load of cloth diapers (or equally dirty load)

Laundry Soap

The best advice is to do a load with the least amount of soap and see if it cleans to your satisfaction. Yes, this might take you a little bit of time to figure out, but in the long run, you'll save a lot of money on soap!

    Does this need to be used with a water softener?

    How much suds does your laundry soap produce? We have hard water and are using a water softener. I’ve used too much detergent (regular and natural) in the past to where my towels are almost self-sudsing when I wash them. So, if I put in 1 Tbl. of soap and I don’t see suds, are they still getting clean? Thank you.

    I gave up using detergent some months ago, using only my homemade apple cider vinegar instead. Since then the clothes are just as clean, actually look a bit brighter, and my husband’s psoriasis has almost cleared up.

    Hi, Michelle!
    Please explain how soap and detergent work
    differently. A little science is always fun to learn :)
    Thanks!
