Wet surrounding areas and plants before starting. Apply undiluted POWER CLEAN to wet surface using a garden spray, brush or roller. (No thinning required).
Allow POWER CLEAN to remain wet on the surface for approximately 10 minutes. (Do not let the product dry on the surface).
Using a stiff bristle broom, scrub the surface to see if the coating has lifted.
Use a strong jet of water or pressure wash to rinse the surface of the timber. Repeat if necessary.
Follow up with DEX PREP to neutralise the timber and rid the surface of any darkening which may occur in the cleaning process. (1L DEX PREP : 1L Water).
