Plastic windows should be cleaned regularly. Be sure to hose or blow off loose dirt particles from surface and then use either plain water or mild soap and water solution. DO NOT USE HARSH DETERGENTS. Apply with a clean, soft cloth or microfiber towel to gently clean the window. Never use harsh brushes or abrasives when cleaning plastic windows.
The effects of sunlight combined with environmental pollution can alter the chemical structure of your plastic window, resulting in permanent discoloration and brittleness.
To maintain the clarity and extend the life of your plastic window, we recommend that you regularly wash dirt and salt off the surfaces.
