We recommend that you clean your windows and doors every two to three months. The best way to clean the frames is with warm soapy water, then wipe them dry with a soft cloth. If there are stubborn stains on the frames you can use a cleaner such as JIF, but use it sparingly and carefully. Glass can be cleaned with soapy water or glass cleaner. If you are using commercial glass cleaner be careful not to get too much on the frame. Avoid using abrasive cloths or scourers, bleach, solvents or acids, or high-pressure water blasting. For ease of cleaning your windows can be coated with an EnduroShield easy clean protective coating.
