Of course, another great benefit of vinyl siding is how easy it is to clean and maintain, but a frequently asked question is “how do you clean vinyl siding?” Since it is such a large investment you don’t want to use any cleaning solutions or materials that could harm your siding.
For best appearance, it is suggested that you clean your vinyl siding at least once a year.
Vinyl siding resists most common household stains, but it will become dirty like any product exposed to atmospheric conditions. In areas not exposed to direct sun and rain, periodic washing with a soft bristle brush, clean water from a garden hose and a bucket of soapy water (you can use the solution described below) may be necessary to remove surface dirt or chalk.
To minimize streaking, wash the house from the bottom up. Thoroughly rinse the siding with clean water from a garden hose and avoid getting cleaning solution on surrounding fixtures and surfaces.
Mildew may be a problem in some areas, especially warmer climates with consistently high humidity. Mildew appears as black spots on surface dirt and is usually detected in areas not subjected to rainfall, such as under eaves and porch enclosures. To remove mildew, prepare a solution as follows:
1/2 cup detergent (ex. Tide)
2/3 cup trisodium phosphate (ex. Soilax)
1 quart 5% sodium hypochlorite (ex. Chlorox)
3 quarts water
CAUTION: Greater concentration may cause damage to the siding and soffit *** Always test any cleaner on an inconspicuous area before full use ***
If the above solution does not readily remove mildew spots, ask your contractor or your local building materials retailer for a mildew cleaner.
