Chemicals for Specific Exterior Cleaning

Critical Steps to Prevent Risks and Ensure Satisfied Customers:

  1. Before cleaning, test each product on a hidden area of the surface to be cleaned.

  2. Inspect all areas to be cleaned, taking note of any stained wood (doors or decks), cameras, electrical outlets, solar panels, lights and fans. Protect as necessary. Also be careful to prevent runoff into koi fish ponds. Communicate with customer about any existing damage, oxidation, old paint or pre-existing dead plants before starting job.

  3. Apply a pre-cleaning fresh water rinse to any plants that may get overspray or run off and that may be damaged by cleaning solutions. Saturate gutter runoff ground
    areas with fresh water.

  4. Always use the appropriate personal protection equipment, including a respirator, goggles and protective clothing.

  5. Completely cover roof with cleaning solution from gutter line to peak of roof, walls from ground to gutter line. After 10 minutes, apply more solution to any areas of heavy organic growth still visible.

  6. After cleaning, use fresh water to rinse any plants that may have come in contact with cleaning solution.
