Calcification is the nightmare of every glass surface cleaning, as it can not be cleaned away after some time and make glass look dull and dirty.
Chalk reacts with glass much like acid because chalk literally eats into the glass. Long-term calcification can not be cleaned with any regular cleaning agent and is a case for SmartGlassRepair®!
SmartGlassRepair® fixes your calcified glass surfaces and makes them shine again!
