For light cleaning, rinse with water from bottom to top and back to bottom. This will clean the surface on the way up and prevent the collection of dirty “run down” and possible streaking. Air dry or wipe dry with a soft, dry, lint-free cloth.
If light cleaning does not clean the debris, rinse the surface with clean water from top to bottom. Use a sponge and clean with mild soap and water. Immediately rinse any “run down” to lower parts of the building. Do not allow cleaning solutions to collect or “puddle” on surfaces. Immediately rinse with clean water. It is very important that cleaning solution does not dry on the surface. Air or wipe dry with a soft, dry cloth. For stubborn, water-soluble debris, repeat steps above until clean.
For a protective wax finish, apply a quality brand of car wax to the aluminum surface (follow wax manufacturer’s application instructions)
For optimal cleaning, do not clean coated aluminum surfaces in direct sunlight or in temperatures too hot or too cold. Do not use abrasive cleaners that may scratch the cladding and avoid excessive rubbing or over-cleaning.
