How to clean commercial glass

Installing your specialist glass is an exciting experience, and there is no better way to show it off than to have it sparkling clean. Here’s how can you correctly clean your commercial glass.

During construction

Glass cleaning is usually conducted after completion of the building. However, taking care to protect and shelter glass throughout the construction work will make the task of cleaning it significantly easier, and will also protect it from damage. During construction you should:

  • Install temporary screens to shelter the glass pane, particularly if welding, sandblasting, floor sanding, cuffing or other potentially damaging construction practices are taking place near the glass.
  • Remember that glass installations which are adjacent to concrete (e.g. concrete slab floors) require extra care and cleaning due to the abrasive nature of concrete dust.
  • Advise all tradespeople to be aware of damaging glass and windows and to leave in place any materials protecting them.

Cleaning toughened glass

The cleaning of toughened glass requires special care due to the presence of pickup on the glass surface. Pickup is a deposit of very small particles of glass which are fused to the glass surface. It’s important that your cleaning process does not dislodge these particles. We suggest that you:

  • Avoid using blades or scrapers as this can dislodge pick up.
  • Use a soft cloth where possible.
  • Consult with glass suppliers to find suitable cleaning equipment.

Cleaning special products e.g. Low-E or reflective glass

Special coated high performance glass such as Low-E or reflective glass requires a specific cleaning method:

  • To remove residue, apply a small amount of muriatic acid to a clean, dry, lint-free cloth or paper towel.
  • Do not apply cleaner directly to the glass surface
  • On the affected area, work the cloth in multiple directions until the residue is removed.
  • Avoid getting cleaning agents on any non-glass components.
  • Never use a razor blade or metallic object to remove debris.

What not to do…

  • Do not use cleaners that contain Hydrofluoric or Phosphoric acid as they are corrosive to the glass surface.
  • Do not clean the glass when the glass is hot or in direct sunlight.
  • Do not allow cleaning solutions to contact the edges of laminated glass, insulating glass units or mirrors.
  • Do not store or place other material in contact with the glass, as this can damage the it or create a heat trap, leading to thermal breakage.
  • Abrasive cleaners, powder based cleaners, scouring pads or other harsh materials should not be used to clean windows or other glass products.
  • Avoid causing extreme temperature changes to the glass as this may lead to thermal fracture of the glass. For example, do not splash hot water on cold glass, or freezing water on hot glass.
  • Some tapes or adhesives can stain or damage glass surfaces. Avoid using such materials unless they are known to be easily removed.
