Marvin's clad-wood windows feature a low-maintenance extruded aluminum cladding with a commercial grade finish that offers you a beautiful, low-maintenance exterior.

Washing Cladding

Light surface dirt is usually washed off by normal rainfall. Surface dirt can also be removed with a wash and rinsed with clear water. Use a soft brush such as a long-handled car washing brush.

If you wish, you can use a mild detergent (such as dish soap) to remove any bugs, grime, dirt or dust that may gather on the aluminum cladding. To be sure your cleaning solution will not harm the factory-applied clad finish, test your cleaning solution on an inconspicuous area before washing cladding.

A thorough, clear water rinse should follow. After rinsing well and drying, you can use car wax to add shine.

Over-cleaning or scrubbing a coated metal surface can do more harm than good to its surface life. Do not use solvents or abrasive-type cleaners on any coated surface.

Information regarding cleaning and maintenance recommendations for clad product installed in coastal areas is available in the Aluminum Clad Products in Coastal Environments section of the Service and Maintenance section.

Exterior Mildew Removal

The presence of mildew on your exterior can be confirmed by placing a drop of household bleach on the suspected mildew area. If small gas bubbles develop in the droplet of bleach and the area bleaches out, mildew does exist and should be removed from the exterior of your windows or doors.

Use this basic solution for removing exterior mildew.

  • 1/3 cup (80 ml) powder laundry detergent
  • 2/3 cup (155 ml) trisodium phosphate (TSP), such as Soilex
  • 1 quart (1 liter) household bleach
  • 3 quarts (3 liters) water

Please note: A stronger concentration of cleaner can damage the coating surface or finish.

  1. Always wear protective eyewear and skin protection when using harsh cleaning compounds.
     
  2. Apply the solution with a soft bristle brush using medium pressure.
     
  3. Rinse the finish well with clear water after cleaning.
     

Removing Caulk

Caulking tars and similar substances can be removed with mineral spirits. Use a soft bristle brush with medium pressure. A clear water rinse should follow. Be sure to follow label directions for use and disposal of mineral spirits, and wear protective eyewear and clothing.
