How to Clean Your Vinyl Siding Without Causing Damage
Daily life naturally deposits dirt, dust, and grime on your home’s exterior. Textured vinyl siding can trap these particles in small cracks and crevices, and over time, mildew may develop, especially on lighter-colored siding.
The safest way to clean vinyl siding is using a garden hose along with a soft-bristled brush. A long-handled car washing brush works well for hard-to-reach areas.
General Cleaning
For light dirt, start by rinsing the siding from top to bottom with a garden hose.
Moderate dirt requires more effort: combine a garden hose with a soft-bristled brush or long-handled car washing brush for best results.
Heavy industrial dirt calls for a cleaning solution:
-
1/3 cup detergent
-
2/3 cup trisodium phosphate
-
1 gallon water
Apply the solution gently with a soft brush, then rinse thoroughly.
Removing Mildew
Mildew, especially black spots, responds well to a slightly stronger mix:
-
1/3 cup detergent
-
2/3 cup trisodium phosphate
-
1 quart sodium hypochlorite (5% solution)
-
3 quarts water
Carefully apply the solution, rinse with clear water, and avoid contact with skin and eyes.
Cleaning Tips & Warnings
-
Always rinse from top to bottom to minimize streaking.
-
Avoid abrasive cleaners or strong solvents, which can damage siding.
-
Never use a pressure washer; it can crack panels or unlock them, potentially voiding your warranty.
