What to Consider When Buying Vinyl Siding Cleaner

Vinyl siding is a low-cost, easy-to-install cladding option for your home. Although it’s relatively easy to clean, you’ll still need the right cleaner. I’ve used my experience cleaning vinyl siding, as well as the expert advice of Vince Christofora, owner of Woodstock Hardware, to compile a list of quality, effective options.

Keep these considerations in mind to buy the best product for your situation.

  • Application method: According to Christofra, vinyl siding cleaner application methods vary from applying-and-forgetting to hand-scrubbing and pressure washing. Although the spray-and-forget products have their niche,  he says “nothing beats applying either by hand and scrubbing or pressure washing.” Especially dirty siding may require scrubbing and pressure washing.
  • Vinyl condition: Loose or unfastened siding pieces should be secured before you begin cleaning. Make sure you follow recommended pressure washing techniques and use the “cleaning” nozzle to prevent damaging your siding.
  • Earth friendliness: Many of these cleaners are environmentally friendly, although none are all-natural. Products that contain bleach require extra precautions. You should cover any exposed skin, as well as nearby plants. Christofora recommends pre-soaking and a final rinsing with your hose of any areas surrounding the siding. This minimizes how much cleaning solution may be absorbed into plants, landscaping, decking and outdoor furniture.
  • Cost: Vinyl siding cleaners are relatively inexpensive, ranging from $15 to $40 per gallon and covering 700 to 4,000 square feet.

This bleach-based product, Star Brite All Surface Mold Stain & Mildew Stain Remover, is not practical for whole-house use because it comes in a 23-oz. spray bottle. But it’s great for spot-cleaning stains and moldy areas. It’s also effective on outdoor acrylic fabrics and vinyl upholstery.
