Pro-Kleen Patio and Driveway Cleaner 20L Cleaning Liquid 5L 4 Pack

Revive your patio, driveway, and paving! Pro-Kleen Patio and Driveway Cleaner blasts away dirt and grime from patios, driveways, block paving, concrete flags, steps, and paths, leaving surfaces looking brand new. Simply apply the solution-use a watering can or pressure sprayer for even coverage-and let it work its magic for two hours (or overnight for stubborn stains). A stiff brush will speed things up. Rinse thoroughly with a hose. For heavily soiled areas, a second application may be needed. Keep children and pets off the treated area until completely dry. Don't use if rain is expected within eight hours. This 20L container will handle even the largest spaces.
