Sulfamic acid rust removal

• When compared to other strong and most common
  strong mineral acids, the sulfamic acid has low
  toxicity, low volatility, and water descaling
  properties.
• 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.

Sulfamic Acid Vs. Citric Acid

• Problems involved with use of water are caused by
  the dissolved solids. Chemical reaction produce
  insoluble compounds known as scale. Sulfamic acid
  was found to be the better solution than citric
  acid heat exchanger piping scale removal.

Sulfamic Acid uses

• Sulfamic acid is a safe and powerful acid
  suitable for descaling applications and acid
  cleaning. Most common use of sulfamic acid is for
  descaling heating coils and heated vessels in
  food handling premises.
• Sulfamic acid is a super-efficient agent for
  descaling, used for cleaning domestic appliances
  and industrial equipment, and an acidic cleaning
  agent, mostly on ceramics and metals. In
  households, it is used as a descaling agent in
  detergents, cleaners and toilet cleaners for lime
  scale removal
