you spritz it on glass naman and wipe it off. ok lang yun, but if it contains ammonia, don't speay it on the inside or tint. ammonia will damage the tint.

try mo nalang pa polish yung windshield nyo sa mga detailing shops like bigberts. then after polish maintain mo nalang linisin yung windshield glass ng glass cleaner like Eagle 1.
