Vinyl siding cleaning: Pressure washer or soft brush?

vinyl siding cleaning - Clover CleanVinyl siding cleaning is an important part of maintaining your house or strata building. Mold, mildew, and algae forms quickly on siding in our damp Lower Mainland winters. Neglected dirt makes your building unsightly, and also shortens the life of your vinyl siding.

Homeowners and property managers often ask us why Clover Clean prefers to wash vinyl siding by hand using soft brushes instead of our pressure washers. If you’ve read any power washing siding tips on the Internet, you know there’s a variety of opinion out there.

Siding experts do not strictly forbid using a pressure washer on vinyl siding. Some brands of washers will work. Additionally, a wide angle spray helps reduce potential damage to siding. But if you choose to clean your siding with a power washer, be careful. Most pressure washer manufacturers suggest using a straight on or downward approach to avoid getting water under your siding. If you spray water under your siding, you risk damaging your house.

But isn’t high pressure water more effective at removing mold, mildew, and algae from vinyl siding?

If you have access to a power washer, it might seem like a quick and easy solution. However, siding experts agree that it’s more important to attack mold, mildew, and algae with proper cleaning solutions and a professional soft brush.

Why we use soft brushes for vinyl siding cleaning

In addition to the reasons against using a power washer on vinyl siding mentioned above, here are four reasons we use soft brushes:

Most vinyl siding styles have textures to make them look like wood or stone. Mold and algae cling to the small grooves in textured siding. The bristles of soft brushes get into these finer textures and remove stubborn dirt and algae.


Using a soft brush for vinyl siding cleaning around windows is important. A power washer might get the job done fast, but around windows you risk spraying water between the siding and the windows. Over time, high pressure water also loosens caulking. Water that gets behind siding potentially damages the wood underneath.


Most of all, our customers are consistently happier with the results of hand washing vinyl siding. Power washing might give you a quick clean look, but hand washing is more effective and long-lasting.

The fourth reason is an important one for us. We’re only satisfied with our work when our customers are satisfied.
