Buying Guide

What to consider when choosing exterior cleaners

  • Surface type: Vinyl siding, brick, stucco, metal roofs, and gutters require different formulations. Soft wash surfactants are gentler on delicate surfaces, while stronger cleaners work for heavy grime.
  • Application method: Spray-and-rinse cleaners suit quick maintenance; brush-and-wucket tools help for stubborn buildup. Consider whether you have a pressure washer or rely on hand cleaning.
  • Fragrance and odor: Some cleaners offer pleasant scents; consider sensitivities for pets and indoor exposure during application.
  • Dilution and equipment: Concentrates require correct dilution. Ensure compatibility with your pressure washer, downstream injector, or soft wash system.
  • Eco-friendliness: If environmental impact is a priority, choose products marketed as eco-friendly or non-toxic and pair with water-safe tools like vinyl siding brushes.

Surface-specific tips

  • Vinyl siding: Use a soft-winish approach to prevent scuffs. Start from the bottom and work upward with a gentle spray pattern.
  • Siding and gutters: Soft wash formulations help preserve finishes. Rinse thoroughly to avoid residue that can attract more dirt.
  • Roofs: Surfactants designed for roof washing help remove moss, algae, and dirt without harsh scrubbing; test on a small area first to avoid damage on delicate surfaces.

Storage and safety

  • Store cleaners in a cool, dry place away from direct sunlight. Keep containers sealed.
  • Wear protective gloves and eye protection when mixing or applying concentrates. Ensure good ventilation.
