Safe to use on stainless steel.  Will affect brass, copper, and gold coatings.  Safe for use on chromium plating for short periods of time.  Not safe for use on galvanised finishes. If unsure, use with caution, or not at all. Always test on material surface before using.


Pack contains 200 grams of sulphamic acid – enough to produce ONE litre of a strong descaling solution when mixed with 1 litre of cool water.  It is possible to use more water than one litre for a weakened solution, but DO NOT use less than one litre of water per sachet as the powder will not fully dissolve.  Product dissolves easier in warm water, and heating aids the descaling process.
