Cleaning Tips

The following important glass cleaning tips highlight areas not covered in the two GANA Glass Information Bulletins:

Commence cleaning as soon as the glass is visibly dirty.

Avoid cleaning tinted and reflective glasses in direct sunlight as the glass will be excessively hot for optimum cleaning.

Washing of the glass should be preceded by a thorough cold-water flushing to remove all surface grit.

Glass should be washed using a soft, clean, grit-free cloth and a mild soap, detergent, or slightly acidic cleaning solution. Glass should be rinsed immediately with clean water, and the excess water should be removed with a clean squeegee, or a clean, lint-free cloth. Do not allow metal squeegee holders to touch the glass surface.

If paint or glazing compounds have to be removed from the surface, conventional cleaners and solvents should be used. Do not use razor blades or broad knife blades to remove these contaminants except as outlined in the GANA bulletins.

Solutions that are strongly alkaline or acidic, fluoride salts or hydrogen fluoride producing compounds, must not be used.

Fingerprints, grease stains, smears, dirt, scum, sealant residue, scratches and abrasions are more noticeable on coated glass than on uncoated glass. Extra care should be exercised in handling and cleaning to keep such markings off of the glass.

Abrasive cleaners must not be used on first-surface reflective glass products.
