How to make powdered laundry detergent

Laundry detergents have always been problematic for me. Certain brands irritate my skin, and I’ve never been able to pinpoint what ingredient is the problem. Even if I knew, most laundry detergents don’t exactly provide a list of ingredients I could check. Luckily, laundry detergent is easy to make. Doing it yourself not only allows you to control what ingredients are in your detergent, it also saves a ton of money.

My recipe uses four basic ingredients stocked by many supermarkets now, and one optional ingredient.

Ingredients:

• 2 parts Borax
• 2 parts Washing Soda
• 1 part Grated Bar Soap
• 0.25 part Baking Soda
• Optional Fragrance Oil or Essential Oil  

Prep:

You’ll want a clean, dry, lidded container or bag to store your homemade laundry detergent. If the container isn’t air-tight, the detergent may clump from moisture in the air. Usually it’s easy to break it up, so this isn’t a big problem. If you don’t do laundry very often, though, you probably want to store it in something with a good seal.

The soap can be anything. Most people start out using a laundry soap like Fels Naptha. Once I started making my own soap, I switched to using whatever basic recipe soap I had on hand. You can grate it by hand with a cheese grater or with a shredding disk on a food processor. 

Make it:

Combine the first four ingredients in a large mixing bowl. If you’re not familiar with the “parts” measurement, it’s a simple way of making a recipe fit whatever amount you need by giving the amounts as a ratio instead of a specific measurement. You could substitute “cup” for “parts” if that makes it easier.  

Options:

Leave it unscented, use a scented bar of soap, or add your choice of fragrance or essential oil to the combined ingredients and stir to combine. I usually use about half an ounce of fragrance oil per batch. With essential oils, I usually start with 15 drops or so and see how it smells before adding any more. I’ve heard you could use your favorite cologne or perfume, but I haven’t personally tried it. 

Use it:

I use about two tablespoons per load in my top loading machine. You can use one tablespoon for lightly soiled loads, but with my family, every load is a two tablespoon load.
