Cleaning Windshields, Windows and Solar Panels
Use a liquid household glass cleaner to remove normal dust and dirt. To remove oil, grease or road tar, use isopropyl alcohol, then wash these surfaces with water. Dry gently with a soft cloth or chamois.
NOTICE
Be very careful when cleaning acrylic surfaces as they
can be scratched or damaged. Do not use a cleaner with an abrasive,
a combination cleaner and wax or any solvent that contains ethyl or
methyl alcohol. Do not use products containing ammonia, soaps, or
abrasives. Never use gasoline or cleaning solvent. These products
scratch or destroy acrylic surfaces.
