Sulphamic acid is a powerful yet easy-to-handle acid widely used in cleaning, descaling, and water treatment applications. Usually supplied as a white crystalline powder, sulphamic acid is valued for its effectiveness in removing limescale, mineral deposits, and rust from industrial equipment and systems. Its stable, non-volatile nature makes it a practical alternative to many liquid acids in commercial environments. Sulphamic acid is also recognised for delivering reliable cleaning performance while supporting efficient maintenance and process optimisation.
