Homemade Laundry Soap

I thought Borax was a safe all natural cleaner, but I read "Borax: Is it Safe?" at Passionate Homemaking and found that borax may not be safe. Until I know more, I will not use it for household cleaning or in my laundry soap.

{Revised} Laundry Soap Recipe

1 cup grated Castile soap (I use Kirk's Castile - an all natural and vegan coconut oil soap and only 99 cents a bar)

1 cup of washing soda
1 cup of baking soda
1/3 cup salt

Mix dry ingredients together and use as a powdered detergent.


To use it this way, I start the cycle on hot water, add 2 T of detergent just until the detergent dissolves, then I change it to cold/cool water and add the clothes.

Or to make a liquid detergent, combine ingredients in a quart of water on the stove, heating just until dissolved. Then fill a recycled gallon container or jug 3/4 full of warm water and add the dissolved soap.


This is more concentrated than my recipe before, so it will take up less space and should last just as long. To use, I will try 1/4 cup and see how it works. I used a 1/2 cup before. (It may need to be stirred before using).

I use vinegar for the rinse cycle, but I like the suggestion to toss a rag with essential oil on it into the dryer for scent, so will have to try that and leave it out of my recipe.

Battling Mount Washmore is still a challenge around here, but it always helps to have a fresh, inexpensive, eco-friendly batch of laundry soap to conquer it!
