Has anyone, or does anyone clean the glass inside a car wash? I've been maintaing the glass for a couple of months, but now the owner wants a deep clean done, all the hard water removed!! The glass is in a pretty bad way, almost white until about halfway up! The glass sections are about 10ft high by 6ft wide and there are 3 pieces, any experience on whats the best product to use and time involved??
Regards
Steve
