Remove any solid excreta left by cats and dogs, test Wash Off-Outdoor Cleaner-Neutraliser on a small hidden area of the surface to be treated to test adverse effects such as discolouration. Shake bottle before use, then apply Wash Off-Outdoor Cleaner-Neutraliser onto soiled areas. Scrub the affected area with a household brush or floor cloth using small circle movements to ensure total soiled area is covered. No rinsing required. A single application of Wash Off-Outdoor Cleaner-Neutraliser will clean the soiled area and will usually discourage cats and dogs from further fouling. If soiling persists, repeat treatment every 12 hours. Use sparingly and avoid over-application. Do not use where human or animal food or water could become contaminated.
