If you’re using a greywater recycling system on your homestead, you already know that harsh detergents and soaps are a no-no. You can buy natural detergents, but some of them are ridiculously expensive. The point is to spend less money not more, am I right? After looking around, googling, thinking and experimenting, we have come up with a very simple recipe for DIY laundry soap that is safe for your greywater system. It won’t hurt your plants and won’t harm the soil or the environment. It’s also pretty cheap to make. Cool, huh?

This recipe is very easy. You simply combine equal parts of everything (like maybe 1/4 cup each) and mix it all together in a container. One small scoop per load does the trick. Most recipes call for lye or Fels Naptha soap, but with the yucca root powder or soapnut powder, it isn’t necessary. They are the “soaps” instead of lye or Fels Naptha. This recipe has no fragrance, but you could add an essential oil to it if you want it to smell nice. You could also technically use soapnut or yucca powder all by themselves as a totally natural laundry soap.

If you don’t want to buy washing soda or if you have an absolutely humongous box of baking soda (like we do for some reason), you can make some washing soda by spreading baking soda on a cookie sheet and baking it at 425 for up to an hour, stirring about halfway through the time. (At 400 degrees, baking soda undergoes a chemical process that changes it into washing soda.)

When rinsing your laundry, add 1/2 cup of vinegar to every 5 gallons of rinse water to soften and remove odors. You’re done! Laundry comes out fresh, clean and odor-free. More importantly, the greywater is nontoxic to your garden or your land.

*NOTE: Like many things, both Borax and washing soda can become dangerous to plants if too much is used, so don’t overdo it. This recipe works very well and you don’t need much; a little goes a long way, especially if you are using rainwater (it contains no minerals and it’s naturally soft).
