EcoWasher HydroBoost is a safe and effective alternative to chlorine-based products and can be used in many applications in and around the home. It is based on sodium percarbonate which uses oxygen for stain removal, whitening and deodorizing. HydroBoost is safe to use at all temperatures, on most washable fabrics, and all colors, in hard or soft water, and is compatible with other household cleaners. Also, it produces no harmful by-products which negatively affect the environment. Unlike chlorine bleach, which can merely cover up a stain, EcoWasher HydroBoost attacks and breaks down organic stains to totally remove them from the garment. ​
