Using non-toxic household products can be tricky on a budget, which is why I do my best to make everything I can myself. Not only do I know exactly what’s in it, but it’s so much cheaper than buying an equally non-toxic product instead.

This laundry powder is one of my favorite clean living DIYs! It’s so quick to make and I’ve found it to be extremely effective to clean all of our dirty laundry from musty towels, to my husband’s work clothes, to delicate baby items. (Though when it comes to washing cloth diapers, I use a special formula for homemade cloth diaper detergent.)

How Much Money Does It Save?

The price of laundry powder ingredients and store-bought laundry detergents are always fluctuating, so it’s impossible to give an exact price comparison that will be relevant for you. 

At the time of writing this post, if you leave out the tea tree oil, this detergent costs almost the exact same price as standard detergent brands such as Tide or All. However, it’s made with much cleaner ingredients.

If you buy a more expensive, clean laundry detergent, this will save a significant amount of money.

How to Use

Place the laundry in your washing machine and sprinkle 2-3 tablespoons of powder (depending on the load size) over it and wash as usual. 

I have personally found that the soap particles dissolve even when washing in cold water. However, if you’re concerned, before running a load, you can mix the laundry powder with hot water in a small jar and shake to dissolve before pouring over your laundry.

FAQs

Is borax safe to use when washing laundry?

There is a lot of debate on the safety of borax, however, when washing laundry I don’t see any problem using it. It doesn’t come close to food, and it’s rinsed off completely in the washer.

Can I use homemade laundry powder in an HE washing machine?

Yes, this detergent is low-sudsing, so it will work in an HE machine.

Is it cheaper to make your own washing powder?

Yes, it is typically cheaper to make your own laundry washing powder when compared with store bought detergents made with the same type of healthy ingredients.

Tips for Success

Purchase ingredients in bulk – You’ll be able to save a lot more money than if you just buy enough for a batch or two.

Mix in a well-ventilated area – Even though these ingredients are considered “clean,” the powder can still irritate your lungs if inhaled.

Ingredients

  • Castile bar soap – Lifts grease and dirt off of laundry. You can use half of a large 8.8 ounce bar (what I do), or a whole regular-sized bar.
  • Oxiclean Free – Made from the solid form of hydrogen peroxide. It lifts dirt and stains off of laundry.
  • Borax – Softens the water to prevent mineral buildup and effective cleaner.
  • Washing soda – Breaks down dirt, removes odors, and softens water. 
  • Optional: Tea tree oil – Using it approximately doubles the cost of this laundry powder, however, I love its anti-fungal and anti-bacterial properties.

Step-By-Step Instructions

Castile bar soap ground into fine powder in a food processor.

Step 1: First, cut the bar soap into small chunks, and place it in your food processor. Grind it until it becomes a very fine powder.
