Greywater-Friendly Detergents & Softeners

If you are using greywater to irrigate garden plants, its important to avoid cleaning products with salt or sodium, boron or bleach. For water softeners, avoid sodium-based products and choose a potassium-based one instead.  Here are some recommended detergents for greywater systems:

Laundry detergent: Oasis or ECOs detergents

Dish and hand soap: Oasis All Purpose Cleaner, Dr. Bronner’s, any natural liquid or bar soap

Body products: Look for low- or no-sodium options. Products from Aubrey Organics are some good choices. Check the ingredients lists of other products at the Environmental Working Group’s Skin Deep Cosmetics Database
