How to Clean and Care for Your Vinyl Siding

Vinyl siding is the most popular cladding for homeowners in North America. It is loved for its beauty, easy upkeep and lasting performance. But while vinyl siding is durable and generally low-maintenance, it does require periodic cleaning. Performing the following low-fuss maintenance on your vinyl siding will help ensure it lasts a lifetime. 

How to Clean Vinyl Siding

Wash your vinyl siding with mild soap and water using a soft cloth or long-handled, soft-bristled brush. If your siding has a textured surface, use only a soft bristle brush to remove stains in the grooves. Start at the bottom of the house and work your way up, rinsing the cleaning solution completely before it dries. 

Not all siding manufacturers approve cleaning with power washers, so first check the manufacturer’s recommendation. If you do use a power washer, hold it straight at eye level to keep the water on top of the siding and prevent driving water behind the siding. 

What Types of Cleaners to Use

Mild soap and water will generally do the trick for vinyl siding, but if you need something a little stronger for dirt or bird droppings, you may use a multi-purpose cleaner. For precaution, make sure to spot-check the cleaner before using it on a large section of siding. After using the cleaner, be sure to rinse it with water. Don’t use cleaners containing abrasive particles, solvent or ammoniated-type cleaners, or paint removers. 

How to Remove Mould and Mildew

For hard-to-remove dirt, wipe the siding down with a solution that includes 1/3 cup powdered detergent, 2/3 cup household cleaner and 1 gallon (3.78 litres) of water. If mildew is an issue, prepare the solution mentioned above but substitute 1 quart  (1 litre) of laundry bleach for 1 quart (1 litre) of water.

How to Protect Vinyl Siding from Discoloration and Heat

If you use stains, sealants or wet concrete for a home renovation project, be sure to cover your vinyl siding. Some insecticides and herbicides also can stain vinyl siding, so consult product labels before applying. Additionally, vinyl siding can melt when exposed to a significant heat source, so do not keep nearby barbecue grills or other ignitable materials such as dry leaves, mulch and trash.
