Maintenance Tips

Maintenance Tips

Wardco windows and doors are the closest to a maintenance-free product that you can find among exterior building products. However, they can become dirty like any other product that is exposed to atmospheric conditions.

With little effort, you can keep your vinyl window frames clean. In most cases, a heavy rain is all that is needed to clean them. Avoid washing windows with a high pressure spray. If rain does not do a satisfactory job, follow these simple instructions. These instructions are based on a study that was conducted by the Vinyl Window and Door Institute on the efficiency of cleaning vinyl window frames after two years of outdoor exposure.


Normal Maintenance

  • Wash using a soft cloth or ordinary-handled soft bristle brush.
  • For difficult to remove dirt and stains such as topsoil, lithium grease, crayon, felt-tip pen, caulking, lipstick, grass, bubble gum, mold and mildew: use the readily available household cleansers on the suggested list below. Always follow the manufacturer's directions on cleansers.
  • Do not use mildly abrasive cleaners such as Ajax®, Bon Ami®, etc. These or any abrasive materials could have a negative effect on the surface of glass and window frames.
  • Do not use cleansers containing aggressive organic solvents because they could affect the surface appearance of the vinyl. Examples of such cleansers are chlorine bleach, liquid grease remover, nail polish remover and furniture polish/cleansers.

Cleaning Screens


  • Follow exterior surface cleaning instructions for all exterior screens. Interior mounted screens can be vacuumed with a soft brush attachment or wiped with a soap and water solution. Use caution when removing and handling insect screens. Torn insect screens or bent screen bars are not covered by warranty.
  • An easy way to clean an insect screen is to remove it and lay it down on a flat surface. Apply a cleaning solution to the screen and let it soak for a minute. Then, rinse the screen using a low-pressure spray, such as a garden hose.

Cleaning Glass


  • Apply a mild soap or vinegar-based cleaner to the glass, by spraying or using a clean, grit-free cloth or sponge saturated with cleaning solution. Avoid using ammonia or alcohol-based cleaners, which can cause streaking. Be careful not to damage glazing, frame finish, wood components or insulating unit seals by overgenerous application of cleaners.
