Sodium hypochlorite

Sodium hypochlorite is the active ingredient in most household bleaches. It fights germs even at very low concentrations and is excellent at removing stains and unpleasant odours. Numerous scientific studies have shown it to be safe when used as directed on the product label. And as bleach disintegrates almost entirely into salt and water it’s safe to go down the drain.
