Dilution: Use undiluted (straight)
Application: Pre-wet (do not soak). Apply using a low-pressure sprayer. One application with a five minute dwell time removes many stains. For deep stain removal from porous surfaces, pre wet (do not soak) the surface with water. Use a double undiluted application, spaced three to five minutes apart without rinsing in between the applications. Additional applications may be necessary. When cleaning glass, use single applications. Additional applications may be necessary. When cleaning glass, use single application to allow to dwell, rinse with clean water before drying and before squeegee swiping.
Rinsing: Always rinse thoroughly, before product dries. Rinse pressure is determined by the skill set of the washer and sensitivity of the surface. Use lower rinse pressure when cleaning sensitive substrates (limestone, sandstone, etc…) When in doubt, consult substrate manufacturer for recommended PSI.
Precautions: Do not allow product to dry. Always rinse thoroughly. Cover landscape or water wet before and after application.
