Can CRYSTAL CLEAR 550 clear some panes of glass and then selectively “burn” others?
A. No. Chemicals can not be selective; CRYSTAL CLEAR 550 is no different. CRYSTAL CLEAR 550 will not clear 500 panes and then “burn” 2 or 3 panes. Those panes that haze must be different from the others. Probable causes can be, panes that are subjected to more runoff, water sprinklers, panes that were possibly installed wrong or were stored incorrectly before installation etc.
