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.
