if using around coloured grout use a weaker solution of approx 2% (20g per litre of water) to reduce the risk of leaching out any colour from the grout.
For descaling equipment use a 10% solution.
Aminosulfonic acid is safe for steel, iron, glass and wood equipment, and may be used with caution on copper, aluminium, and galvanized metal surfaces.

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 Aminosulfonic acid at a rate of 100g to 150g per litre of water.
Aminosulfonic 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.

Aminosulfonic 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%.
