Caring for Vinyl Siding

Vinyl siding is durable, attractive, and easy to maintain. And like any outdoor product, even low-maintenance vinyl siding will need occasional attention. Simply follow the cleaning and maintenance tips on this site and your vinyl siding will always look its best.

Cleaning

How do I wash vinyl siding?

Wash vinyl siding with a soft cloth or ordinary long-handled, soft bristle brush. For textured surfaces, use only a soft bristle brush to keep the grooves in the texture stain-free. For best results, start at the bottom of the house and work up and rinse the cleaning solution completely before it dries. If your house has brick facing, cover the brick so that it is not affected by the runoff.

Can I use a power washer?

Yes, though you should read the washer instructions carefully before use. When cleaning, hold the power washer straight at eye level to keep the water on top of the siding where it can clean most effectively. Do not aim the power washer upward as water may collect behind the siding.

How do I remove mold and mildew?

Small spots of mold and mildew can be handled with cleaners such as Fantastik^® or Windex^®. For larger sections, a solution of vinegar (30%) and water (70%) has proven successful. Alternatively, you also could try the following solution: 1/3 cup (2 2/3 ounces) powdered laundry detergent (e.g., Tide^®, Fab^®, or equivalent), 2/3 cup (5 1/3 ounces) powdered household cleaner (e.g., Spic & Span^®, Soilax^®, or equivalent), 1 quart (32 fluid ounces) liquid laundry bleach, and 1 gallon (128 fluid ounces) of water.

What types of cleaners should I use for other stains?

A list of commonly accepted cleaners is provided in the box below. Be sure to spot check any general or stain specific cleaner before using it on a large section of siding. After removing the stain, rinse thoroughly with water. Do not use cleaners containing organic solvents, undiluted chlorine bleach, liquid grease remover, nail polish remover, or furniture polish or cleaners. They can affect the surface of the siding.

Maintenance

How can I protect vinyl siding from discoloration?
Cover vinyl siding when using stains, sealants, and wet concrete as part of other home renovation projects. Certain insecticides or herbicides can potentially stain vinyl siding. Consult the product labels and/or the insecticide or herbicide manufacturer before applying.

How does heat affect vinyl siding?
Vinyl siding is made from organic materials and can melt when exposed to a significant heat source. Vinyl is a combustible material, but will not readily ignite unless exposed to flames from an existing fire. Home and building owners with all types of siding should always take precautions to keep heat sources such as barbeque grills, and readily ignitable materials such as dry leaves, mulch, and trash away from the structure.

How does heat from reflected light affect vinyl siding?
The typical heat distortion temperature of vinyl siding is approximately 160 to 165 degrees Fahrenheit. When temperatures reach these levels, the siding could distort. Installing screens and awnings and planting bushes or other landscaping can alleviate reflections or radiation that would contribute to those extreme temperatures. Reflected or radiated heat sources include windows, roofing, pavement, and certain underlayments.

Can I paint vinyl siding?
Consult with your vinyl siding manufacturer before painting vinyl siding. Many manufacturers void their warranties if the siding is painted.
