Pilkington Activ Self-Cleaning Glass
Care and Maintenance Guidelines
Attention Homeowner, Building Owner and/or Installer

How does the "Activ" coating work?
The Activ (outside or exterior) surface of the glass absorbs ultra-violet energy from exterior daylight.

Pilkington Activ glass functions in two ways. First, it breaks down organic dirt through a PhotoActiv process. Second, rain water "sheets" down the glass like an Invisible Squeegee rinsing away dirt and debris on the window.

Manual window washing or spot cleaning may be necessary to remove paint, a heavy accumulation of dirt, or other material that can get on the glass.

Please allow 3 to 7 days exposure
to exterior daylight for the glass to become "ACTIVated". thereafter, normal exposure to daylight will keep the glass active.

DO NOT use scouring agents, steel wool, razor blades or other hard objects to clean the Activ glass surface. These materials will permanently damage the glass and void applicable warranties.

Manual Cleaning

Rinse thoroughly with clean, soft water to remove all surface dirt particles. Clean carefully, using a soft cloth or sponge and generous amounts of warm, soapy water. Rinse thoroughly one more time to ensure detergent residue is removed. Following manual cleaning, the glass will naturally re-activate after a few days.
Spot cleaning
For spot cleaning tougher deposits (e.g. paint) use a clean soft cloth and a solvent such as denatured alcohol or acetone with appropriate safety precautions. (Care should be taken to eliminate direct contact between acetone or solvents and vinyl window frames or paint work, as they can be damaged). Rinse thoroughly with clean, soft water.

Dry Weather Conditions
During dry weather, a build-up of dust can be removed with a light spray from a garden hose.

If the hose water is hard, add 2 or 3 drops of liquid dish washing detergent to water in a pint bottle spray garden hose attachment or use a portable 1 or 2 gallon, hand pump pressurized, garden spray bottle with plain distilled water from a hardware store.

Avoid Abrasive Products
Should mortar or cement products come in contact with any glass surface, they need to be thoroughly rinsed off the glass immediately, before hardening. Extreme care must be taken during this rinsing process, as these products are highly abrasive and can physically damage the Activ glass surface.

Silicone Precaution
Do not allow material with silicone to contact the self-cleaning surface. If contact has occurred, wash the contacted area only, with acetone or a proprietary silicone solvent and follow with a detergent wash and clean water rinse. This will reduce the contamination but will probably not eliminate it.
