For light cleaning, mix a solution of Sulfamic Acid Crystals by adding 1/2 cup to 1 gal of clean water
For heavy-duty cleaning, mix 3/4 cup to 1 gal. of clean water
Mix until the crystals are completely dissolved
In cold water, not all of the crystals may dissolve
Pre-wet the surface with clean water

Work small areas do not allow the solution to dry on the surface
Extract all dirty remains with a wet vacuum system
