Directions for Use


  1. Always wear eye protection.
  2. Saturate plants, shrubs and grass with water.
  3. Keep others and animals away from work site.
  4. Test pressure washer for surface compatibility, with and without the cleaner, in an inconspicuous area.
  5. It is best to pressure wash during early morning or dusk hours when the sun is not as intense, or on an overcast, non-windy day.
  6. Do not allow product to dry on surface before rinsing.
  7. Do not allow any contact on any deteriorated or severely oxidized painted, sealed, or stained surfaces unless you intend to refinish.
  8. Pressure washing alone may remove old paint and stains and should be tested on surface prior to cleaning.
  9. For vertical surfaces, solution should be applied working from the bottom up and rinsed using fresh water from the top down to prevent streaking. Never point water stream upward underneath shakes, shingles, or siding.
