Weather, mold, algae and pollen attack outdoor surfaces leaving them looking dull. Brighten the look and remove unsightly stains with a thorough pressure wash using this pro-grade formulation. Before you begin: Saturate plants, shrubs and grass with water. Test pressure washer for surface compatibility, with and without the cleaner, in an inconspicuous area. Rinse and allow to dry before proceeding. Important: Do not use product full strength on any surface. Do not allow product to dry on surface or vehicle before rinsing as staining or spotting may occur. Do not allow contact on any deteriorated painted, sealed, or stained surfaces unless you intend to refinish. Pressure washing alone may remove old paint and stains and should be tested on surface prior to cleaning. For vertical surfaces, solution should be applied working from the bottom up and rinsed using fresh water from the top down to prevent streaking. Application directions: Put pressure washer siphon tube into solution. Use low-pressure spray nozzle to apply solution to surface. Remove the siphon tube from the container. Rinse with the high-pressure nozzle. Saturate plants, shrubs and grass with water after cleaning. Before storage, rinse pressure washer parts thoroughly to prevent damage.
