What to do
For routine glass and mirror cleaning, identify any coating or surrounding sensitive material, remove loose dust, apply a compatible product according to its label, and wipe with a clean cloth. Too much or too little cleaner can leave streaks.
Step-by-step
Check the glass and frame
Look for coatings, films, damaged edges, or adjacent materials that require special care. Follow their maker’s instructions first.
Remove loose dust
Use a clean, appropriate cloth to keep grit from being dragged over the glass.
Apply a suitable glass cleaner
Use the quantity and method stated on the cleaner’s label. Keep the product off materials for which it is not approved.
Wipe and inspect
Wipe with a clean cloth, then inspect from an angle. Change a soiled cloth rather than spreading residue across the surface.
