StoneCare4U Essential Black Spot Remover 5L 2 Pack

StoneCare4U Essential Black Spot Remover effectively eliminates black spots from patios, paving, and paths. This specially formulated cleaner removes stubborn stains from natural stone and other outdoor surfaces. For optimal results, apply, agitate, and allow a two to three-hour dwell time before rinsing. Dirt, grime, algae, lichen, and persistent black spots are removed within two to four hours. Unlike acid-based alternatives, this alkaline formula prevents surface etching or damage. Application:** Pre-clean the area, removing loose debris. Wear appropriate safety gear (gloves, eye protection, mask, and clothing). Use neat or diluted 1:1 with water, test a small area first to determine the ideal dilution and dwell time. Apply via pump sprayer, watering can, or directly from the container. Maintain a wet surface for at least two hours, misting with water if necessary to prevent drying. Use a brush if needed, ensuring the surface remains wet. After two to four hours, rinse with clean water to neutralize, then power wash for best results. Avoid contact with vegetation, rinse thoroughly if contact occurs. For heavily soiled areas or stubborn stains, extend dwell time up to eight hours or overnight before power washing. Aged lichen may require two to three applications and extended dwell times, test first. Caution:** Contains a chlorine-type agent, avoid contact with fabrics and tarmac. May slightly lighten some surfaces—test in an inconspicuous area beforehand. Coverage:** Up to 50m² per 5L (1:1 dilution). Coverage varies with surface contamination. Quantity:** Pack of two 5L containers.
