Beyond the obvious reasons, the most important reason for glass maintenance is to avoid glass degradation. glass will, over time, become permeated with a variety of contaminants:
- hard minerals (from sprinkler systems and building run-off)
- oxidization (from windows encased in metal frames and screens)
- acid rain
- spray, sap ice, snow, sleet and sand
- over spray (from paint, chalking, mortar and more)
In most cases hard mineral or hard water is the biggest threat to most home and business owners and a great source of extra income for professional window cleaners. the need for basic glass restoration can be avoided with regular cleaning to exterior window glass surfaces.
We recommend two cleanings per year.
- Glass is porous. A cross-section of a sheet of glass reveals peaks and valleys.
- Glass is a liquid that continues to harden over time.
- Because glass is porous, it’s easy to understand how it’s transparent look can quickly become obstructed with airborne pollutants.
It’s also understandable how hard water (rain water that runs over a prefabricated surface, i.e. wood stained plank, painted siding, concrete sealant and deposits minerals and acids from those substances into the pores of the glass) can damage glazing if not maintained on a regular basis.
