How to Clean Vinyl Siding

Vinyl siding is the most popular exterior building material in the U.S. because it’s durable, versatile, and resilient. Since it’s exterior facing, it’s subject to the elements such as dirt and grime from pollen, bird droppings, spider webs, and rust. Moss and mildew is also commonly found on vinyl siding in shady, moist areas. To extend the life of vinyl siding and keep it looking beautiful, you should clean it at least once a year.

Use the Right Tools

To clean vinyl siding, you will need trisodium phosphate (TSP), a large bucket, a water flow pole and a soft scrub brush like the Unger Professional™ 10" HydroPower™ Soft Brush with Squeegee. Using the Unger Professional HydroPower™ Pole will allow you to clean without a ladder. You should also have access to a garden hose in order to rinse off the cleaning solution.

Prepare the Area

Before you start cleaning your vinyl siding, you should examine the perimeter to ensure all windows and doors are closed. Turn off the power supply to any outdoor electrical items such as lights and outlets. If there are any plants or surfaces that can be damaged by the cleaning solution, cover them or remove them from the area.

Scrub and Rinse

Visually divide each section of the siding into 10 foot sections so that you can clean one part at a time, making the process more manageable. In a bucket, mix 1 gallon of warm water with the TSP. Then, soak the soft scrub brush in the bucket to absorb the cleaning solution. Starting at the bottom, scrub the siding with the soft brush and the cleaning solution. Once you’ve scrubbed each section clean, attach the water flow pole to a garden hose and rinse off the solution in order to prevent streaks.
