Cleaning Guidelines for Glass and Polycarbonate

Proper handling and cleaning are essential during the installation of glass and polycarbonate to avoid permanent damage to the products. Covenant Security highly recommends strict compliance with the following procedures:

• Apply a mild solution of soap and water or a non-abrasive commercial window-washing solution to the surface uniformly using applicator methods.
• Remove all liquid from the surface immediately with a soft flannel or cotton cloth after applying the cleaning solutions. Avoid trapping any metal, sand, or foreign particles between the cloth and the substrate, as they can damage the glazing if they contact the glass or polycarbonate surface.
• Dry all cleaning solutions from the window gaskets and sealants to prevent potential deterioration caused by the cleaning process.
• Avoid applying cleaners in direct sunlight or at elevated temperatures.
• Do not use razor blades or squeegees to clean hard-to-remove substances, and do not use abrasive or highly alkaline cleaners.
• Never use benzene, gasoline, acetone, MEK, or carbon tetrachloride on polycarbonate surfaces.
• Assume that materials are not compatible unless they have been approved.
• Here are the cleaning agents that are compatible with glass and polycarbonates:

Please note that the list of compatible cleaning agents is not exhaustive and that you should always consult with glazing manufacture for approval before using any cleaning agent that is not listed below:
