Get through that pile of dirty clothes a little easier with our best-selling Laundry Powder! Made with concentrated natural ingredients, this powdered laundry detergent gently cleanses and freshens your clothes without added chemicals such as synthetic fragrances, dyes, or optical brighteners. You'll get approximately 5 loads from the 3 oz sample jar, 33 loads from the 20 oz jar and 80 loads from the 48 oz bag. It is compatible with both HE and standard washing machines, and safe for septic and greywater systems. How to Use: Add 1 tablespoon per standard-size load directly into the washer drum. Do not combine directly with vinegar as this would neutralize its effectiveness, however vinegar can be added during the rinse cycle (or in the fabric softener dispenser of your washing machine). Do not use with silk, wool, or leather. Vegan & Cruelty-Free Ingredients: sodium bicarbonate, sodium carbonate, sodium percarbonate
