Sulfamic acid provides intrinsic safety ergo preferred over hydrochloric acid for household use. Unlike most common acids, sulfamic acid does not form chlorine gas when mixed with hypochlorite-based products. It has replaced hydrochloric acid as a rust remover.
When compared to other strong and most common strong mineral acids, the sulfamic acid has low toxicity, low volatility, and water descaling properties.
