Alumawood shade structures are designed to be virtually maintenance free. In most cases the rainfall is an adequate cleaning source. If cleaning is desired, we recommend the following steps.

Note* Pay close attention to the following areas: under eaves, porches, awnings, and other overhangs that have limited exposure to the natural cleansing effect of rainfall.


Moderate Dirt

An occasional washing with clear water using a garden hose and soft-bristled brush is recommended (a long-handled, car-washing brush is ideal for this purpose).


Heavier Dirt Accumulation

Wash in the manner indicated above, but use the following solution:

  • 1/3 cup detergent (e.g. Tide®)
  • 2/3 cup trisodium phosphate powder (also known as T.S.P.)
  • 1 gallon water

Mildew Accumulation

Mildew can collect on surfaces of all types of building products and is often evident on surfaces that have not been properly maintained. Normally, mildew will appear as black spots. Mildew is easy to remove by using the following cleaning solution:

  • 1/3 cup detergent (e.g. Tide®)
  • 2/3 cup trisodium phosphate powder (also known as T.S.P.)
  • 1 quart sodium hypochloride 5% solution (e.g. Clorox®)
  • 3 quarts water

Environmental Black Streaking

Black streaking can also collect on the surface of a structure as a result of numerous environmental factors. Please consult with the installer on the best way to remove the streaking from your unit.


Caulking Compounds

Use mineral spirits in reasonable amounts, apply directly to foreign substance. Rinse the area thoroughly with water immediately after cleaning.
