After a winter’s worth of weather your siding may be looking a bit dull and dingy. Not to worry. This is typical and is easy to fix. Vinyl siding is a durable building material, but it does require some routine and cleaning.
There are a few reasons that cause this:
- Exposure – it’s outside so there are leaves, rust, snow, rain, pollen, bird and insect droppings, spider webs, and wind blowing dirt and debris against the house.
- Stains – the vinyl siding brands we use, like those from CertainTeed, are designed to resist most common stains, like algae, but they still occur.
- Mildew – damp parts of the home that don’t receive enough sunlight, such as the eaves and porch enclosures, might see mildew growth.
How to Clean Vinyl Siding
Here are the tools and techniques for cleaning your vinyl siding. In the course of a sunny afternoon you can have your home looking as nice as it did when the siding was first installed.
- Soft-bristle brush
- Nylon scrub pad

How to clean vinyl siding
Always follow instructions prescribed by the cleaner manufacturer.
Apply the vinyl siding cleaning solution with a soft-bristle cleaning brush, scrubbing the full length of each lap (the long boards that overlap each other).
To prevent streaking, start at the bottom and work up towards the top of the house.
Use your garden hose to rinse off any residue on each section before it dries.
How to pressure washer / power wash siding
This can be a faster and easier method, although some manufacturers advise against it, and others recommend using a limited amount of pressure, so check their guidelines first.
Be sure that the stream is at eye level and pointed straight at the siding, not at an upward angle. You won’t drive water behind the siding.
Use caution when using a pressure washer around doors, windows, and plumbing connections.
What not to do
To avoid damaging the siding’s surface, do not use highly-abrasive scrubbers, steel wool, paint remover, straight chlorine bleach, paint thinner, spot removers, or liquid grease remover.
When working with chemicals make sure you read all instructions and warnings to avoid injury. Always dispose of chemicals as described by the manufacturer.
We recommend cleaning your siding once a year to avoid build up. With just a little bit of time and effort, vinyl siding can be kept looking its best and will provide many years of trouble-free protection for your home.
