Sulphamic acid is used as an acidic cleaning agent, typically for metals and ceramics. It is a replacement for hydrochloric acid for the removal of rust. In households, it is often found as a descaling agent in detergents, cleaners, and toilet cleaners for the removal of limescale. It dissolves mineral deposits effectively without damaging the underlying surfaces. Sulphamic acid is highly soluble in water, enabling quick and efficient cleaning solutions. Its non-volatile nature reduces the risk of harmful vapors, making it safer for both users and the environment.
