Also called solid hydrogen peroxide, sodium percarbonate is a natural stain remover, whitener, disinfectant, and deodorizer for laundry. Percarbonate is ideal for naturally preserving the whiteness of your laundry, even after many washes, as it prevents graying caused by limescale. Its alkaline pH allows it to soften water, increase the effectiveness of cleaning agents, and dissolve grease. It is also used to treat mold and as a wood brightener for siding, furniture, and outdoor decking.
