Clean Your Vinyl Siding Before Winter

Summer is over, and winter is just around the corner – now is the perfect time to clean your Bellevue Vinyl Siding. Annual cleaning will remove the dirt from summer rains and keep your Bellevue Vinyl Siding looking new. Here are some ideas on how to clean your siding:

Step 1 – Clear Water

Although you can use a pressure washer to clean vinyl siding, if you are diligent, and wash the siding at least once/year, this should not be necessary. It is recommended that you use a garden hose to clean the siding. If there are particularly stubborn areas, a soft bristled long-handled brush is recommended.

If you decide to use a pressure-washer, proceed with caution! Be certain to use a dispersal-type spray tip to avoid damaging the siding. If the pressure is excessive, water can migrate behind the siding, causing rot and other moisture-related damage (mold, etc.)

Step 2 – From the Bottom to the Top

Bellevue Roofing Experts at State Roofing recommend that you begin washing your vinyl siding at the bottom. While this may seem counter-intuitive, the process has been proven to eliminate streaking. As you continue up the house, dirt generally reduces. By cleaning the dirtiest portion first, the streaking from clear water running through excessive dirt will be eliminated.

Continue around the house, completing one side before moving to the next. For excessive dirt, use a soft brush to scrub the area. The most effective way to complete the cleaning is to first rinse the entire area of siding, exposing problem areas, and then come back to the areas that need attention.

Step 3 – Mold & Mildew

After washing your siding down with clear water, chances are there will be areas of mold and/or mildew. The best thing to use for smaller spots is glass cleaner! With a soft rag, spot clean the areas as required.

For larger areas of mold/mildew, the recommended solution is:

30% White Vinegar + 70% Water

Using a soft-bristled, long-handled brush, scrub the areas affected and rinse thoroughly before the solution dries on the siding.

Another effective mold/mildew cleaning solution:

1/3 cup Laundry Soap + 2/3 Cup Spic-and-Span + 1-quart Liquid Bleach

Combine the listed ingredients with 1-gallon of water, mix well, using either a soft rag of a soft bristled brush and clean the affected area, rinsing completely before the solution dries.

Step 4 – Other Dirt

For bird droppings, spider webs and other difficult stains; use:

  • ArmorAll
  • Simple Green
  • Any product that meets Manufacturer Recommendation

Use either the vinegar solution from Step 3 or cleaner like Fantastik or Murphy’s Oil soap to remove:

  • Crayon Marks
  • Felt Marker
  • Oil-based Caulk
  • Grass Stains
  • Grease and Oil Stains
  • Gum (chewing and bubble)

What NOT to Use on Vinyl Siding

There are a number of products that will damage vinyl siding. Do not use:

  • Undiluted Chlorine Bleach
  • Organic Solvents
  • Nail Polish Remover
  • Liquid Grease Remover
  • Spray Furniture Polish

Each of the listed products (and others) can affect the finish of the siding or worse. For best results, use solutions described in Step 3. Always rinse area thoroughly with clean water to avoid streaking.

Keeping Your Siding Clean

The best way to keep your vinyl siding from being stained, always protect the area if working with sealants, concrete, paint or stains. Always read labels of any product you will use around vinyl siding (insecticides, etc.) to make certain overspray will not damage the siding.
