GLASS CARE MAINTENANCE AND CLEANING
2.a. GENERAL CLEANING
Wash, rinse, and dry the glass at frequent intervals particularly during
construction. For all glass surfaces, except coated glass use soft, clean, grit-free
cloths, to apply a solution of a mild soap or detergent in water with a maximum
of 2% concentration, or use a slightly acidic cleaning solution. Do not allow the
soap or cleaning solution to dry on the surface. Follow this immediately with a
high volume of clean water, and prompt removal of excess rinse water with a
clean squeegee. Ensure that not only the glass, but also the surrounding
surfaces are rinsed well.
SOME IMPORTANT CAUTIONS
1. Do not mark or coat glass partially or completely with “x’s” or other symbols with
any material whatsoever. If paper or adhesive is alkaline in character, the
contact area may be attacked directly. If paper or adhesive is neutral or slightly
acid in character, it may “protect” the contact area and permit adjacent exposed
surfaces to weather or age. Although subtle, such conditions are sometimes
sufficiently evident to be annoying.
2. Splatter from welding may cause permanent surface damage, reduce strength,
and lead to breakage.
