HOW TO CLEAN YOUR GLASS

Before cleaning the exterior surface of glass it is important to identify if you have Andersen® 400 Series products that come standard with High- Performance^™ Low-E4^™glass. This type of glass has a low-maintenance exterior coating and removable protective film. The low-maintenance exterior coating is highly durable but may be damaged if abrasive or hard objects are used for cleaning.

To remove dust, dirt, smoke, film, soot and salt spray, use a mild detergent and water solution and a soft cloth or brush. To remove heavy dirt or grime from glass, first wipe loose debris from the glass surface with a soft, dry cloth. Then apply a cleaning solution, such as mild soapy water, vinegar or a liquid window cleaner, and wipe in a circular motion. Remove cleaning solution with a squeegee or a clean, lint-free cloth. As a general practice, you should never clean glass in direct sunlight.

DO NOT use metal razor blades to clean glass or remove paint/stain from glass surface. Scratching of the exterior glass surface could damage the low- maintenance coating.

DO NOT use metal razor blades to remove the protective film. Peel back protective film at a corner using a fingernail or clean plastic scraper.

DO NOT allow any sealants (including silicone) to contact the exterior glass surface. Sealants may cause damage to the exterior low-maintenance coating of the glass.

DO NOT use abrasive cleaners on any glass surface, or on the exterior of High-Performance^™ Low-E4^™ glass.

Note: After cleaning your glass, we recommend to lubricate all moving parts with a multi-purpose dry lubricant spray. Oily lubricants or harsh abrasive cleaners are not recommended. Click here to see our dry lubricant offering
