- How To: Clean Vinyl Siding
Vinyl siding is a durable, versatile, and resilient building material, but it does require some routine care and cleaning.
The growing popularity of vinyl siding is indisputable. Indeed, U.S. Census Bureau statistics indicate that vinyl siding has been the leading exterior cladding in the U.S. since 1995. Its popularity shows no sign of waning; in 2011, 33% of new single-family homes sold in the U.S. were sided in the material. Still, that doesn’t mean homeowners know how to clean vinyl siding—and keep it clean.
Because it is an exterior product, vinyl siding can accumulate a host of dirt, grime, and stains on account of things like pollen, bird and insect droppings, spider webs and rust. In shady, moist areas, mold and mildew can grow, and vinyl is also vulnerable to discoloring effects from insecticides, herbicides, and fertilizers. In addition, vinyl siding’s finish may be marred by a number of commonly used household maintenance products, including caulking, driveway sealant, tar, motor oil and paint.
Luckily, cleaning vinyl siding is a fairly easy job, and there are a wide variety of products to help remove typical stains. Read on, and we’ll show you how to clean vinyl siding the right way.
According to the Vinyl Siding Institute, the best way is to use a soft cloth or an ordinary long-handled, soft-bristle brush. To prevent streaking, start at the bottom and work up towards the top of the house. When cleaning vinyl siding, remember to thoroughly rinse away any residue as you go.
Some good vinyl sider cleaner solutions include:
• 70% water, 30% white vinegar makes a great all-purpose vinyl siding cleaner that removes light mold and mildew stains.
• For a stronger solution, mix together one-third cup powdered laundry detergent, two-thirds cup powdered household cleaner, one quart liquid laundry bleach and one gallon of water.
• If you are concerned about landscaping, use a vinyl siding cleaner solution comprised of one gallon of water mixed with one cup oxygen bleach in a bucket. The oxygen bleach will clean the vinyl without damaging your landscaping.
• Simple Green offers an environmentally friendly cleanser that is specially formulated for use on vinyl and aluminum siding, stucco, terra cotta roof tiles and painted wood. The non-toxic biodegradable concentrate can be used manually or with pressure washers.
• General household cleansers (e.g., Fantastik, Murphy’s Oil Soap, Windex and Lysol) can be used on tough dirt and stains, and including those created by top soil, grass, grease, oil, rust, crayon, ink and bubble gum. Rust stains may be removed using products designed for this purpose (e.g., Super Iron Out and Instant Rust Out).
Cleaning vinyl siding is even easier with a pressure washer, although some manufacturers advise against it, and other manufacturers recommend a limited amount of pressure.
If you’re not sure how to clean vinyl siding with a pressure washer, start by ensuring that the stream is at eye level and pointed straight at the siding, not at an angle. That way, you won’t drive water behind the siding. Use caution when using a pressure washer around openings like windows, doors, and plumbing connections.
Avoid using any vinyl siding cleaners that contain organic solvents, undiluted chlorine bleach, liquid grease remover, nail polish remover, or furniture polish or cleaners. Any of these products might damage the vinyl siding’s surface. Also, avoid using highly-abrasive scrubbers or steel wool; these, too, can cause damage when cleaning vinyl siding.
With just a little bit of time and effort, vinyl siding can be kept looking “like new” and will provide many years of trouble-free protection for your home.
