Sulfamic acid is a colourless, water-soluble compound finds many applications. 
Sulfamic acid melts at 205 °C before decomposing at higher temperatures to water, sulfur trioxide, sulfur dioxide and nitrogen.

Sulfamic acid (H3NSO3) may be considered an intermediate compound between sulfuric acid (H2SO4), and sulfamide (H4N2SO2), effectively replacing a hydroxyl (–OH) group with an amine (–NH2) group at each step. 
This pattern can extend no further in either direction without breaking down the sulfonyl (–SO2–) moiety. 
Sulfamates are derivatives of sulfamic acid.

The simplest of the sulfamic acids consisting of a single sulfur atom covalently bound by single bonds to hydroxy and amino groups and by double bonds to two oxygen atoms.
Sulfamic acid is a white crystalline solid which is non-hygroscopic and stable. 
Sulfamic acid is a super-efficient agent for descaling. 
Sulfamic acid is used for cleaning a number of domestic appliances and industrial equipment.

For cleaning purposes, there are different grades based on application such as GP Grade, SR Grade and TM Grade. 
Sulfamic acid is frequently used for removing rust and limescale, replacing the more volatile and irritating hydrochloric acid, which is cheaper. 
Sulfamic acid is often a component of household descalant, for example, Lime-A-Way Thick Gel contains up to 8% sulfamic acid and has pH 2.0–2.2, or detergents used for removal of limescale. 
When compared to most of the common strong mineral acids, sulfamic acid has desirable water descaling properties, low volatility, and low toxicity. 
Sulfamic acid forms water-soluble salts of calcium and ferric iron.

Sulfamic acid is preferable to hydrochloric acid in household use, due to Sulfamic acids intrinsic safety. 
If erroneously mixed with hypochlorite based products such as bleach, Sulfamic acid does not form chlorine gas, whereas the most common acids would; the reaction (neutralisation) with ammonia, produces a salt, as depicted in the section above.

Sulfamic acid also finds applications in the industrial cleaning of dairy and brewhouse equipment. 
Although Sulfamic acid is considered less corrosive than hydrochloric acid, corrosion inhibitors are often added to the commercial cleansers of which Sulfamic acid is a component. 
Sulfamic acid can be used as a descalant for descaling home coffee and espresso machines and in denture cleaners.

Also known as amidosulfonic acid; amidosulfuric acid, Sulfamic acid; aminosulfonic acid; kyselina aminosulfonova; suphamidic acid; sulfamidsäure in German; acido sulfamidico in Spanish; acide sulfamidique in French, is a weak organic acid with marked characteristics that set it apart from acetic and formic acids:
• Sulfamic acid is a stronger weak acid than both acetic and formic.
• Solid, crystalline powder which dissolves easily in water.
• A powder with melting point of 205°C.
• Non hydroscopic.
• Very stable and easy to transport.
• Less toxic
• Good history of use, common in domestic and industrial cleaning products designed to remove scale deposits.

Clean in a soak tank or by circulation. For surfaces, apply to surface using a cloth or brush and allow to work for a few minutes. 
Agitate with brush if necessary and rinse thoroughly with clean water.
For Boiler systems & Cooling Towers use a circulation treatment of a 10% to 15% solution depending on how bad the system is. 
Before applying flush out system and refill with clean water. 
Determine the volume of water and mix in the Sulfamic acid at a rate of 100g to 150g per litre of water. 
Sulfamic acid may be necessary to add a corrosion inhibitor to help protect mild steel, brass, copper and stainless steel from acid attack. 

Circulate the solution at room temperature or heated to a maximum of 60C for heavier cleaning for several hours until desired results are achieved. 
Note: Do not use at boiling point or product will undergo hydrolysis and will not work. 
Do not use on galvanised materials, zinc or aluminium. 
Sulfamic acid will not remove silica or calcium phosphate scales. 
After cleaning rinse thoroughly and check system. 

Neutralise with 1 to 2% sodium carbonate solution (soda ash) with a target pH of 6 to 8 or whatever discharge pH range applies.
Repeat applications may be necessary for heavily soiled systems. 
After cleaning Periodic flushing of the system to remove loosened scale and contaminants will be necessary.
For rust removal use a solution of 10%-20%.
