Ensure your driveway remains free of debris by utilising the StoneCare4U Driveway Cleaner 5L. This product is designed for various outdoor stone and masonry surfaces, such as driveways, pavers, pathways, block paving, and patios, as well as natural and engineered stone. It is a powerful cleaner specifically formulated for external natural stone driveways. The solution is effective in removing algae, lichen, and black spots, as well as both recent and aged dirt and grime. Leave it on for 2 hours for optimal results. Unlike acid cleaners, this acid-free, alkaline-based cleaner will not harm or corrode the surface. Please note that it is not recommended for tarmac driveways. How to apply: Before use remove any loose debris from the driveway, and ensure you have adequate safety wear, i.e. gloves, suitable protective eyewear, face mask and clothing. It is to be used neat or diluted 1:1 with clean water – always perform a small test area to determine a suitable dilution rate and dwell time. Carefully transfer the cleaning fluid from the bottle to a pump sprayer or watering can. If these containers are not available then cleaning fluid can be used directly from the bucket. The cleaning fluid needs to be left on the surface for at least an hour, during that time the surface must not be allowed to dry out. If necessary mist with additional cleaning fluid or with clean water to prevent the driveway from drying. Work the area(s) of staining with a brush, if necessary, but ensure the surface remains wet at all times. After at least two hours of dwell time, the treated area should be washed down with clean water first to neutralise the cleaner before then power washing off for perfect results. Please note the cleaning fluid can harm or possibly kill vegetation so try to avoid washing off onto garden or lawn grass. If this is unavoidable then rinse with plenty of clean water to dilute the cleaner. In areas of heavy soiling and extreme, stubborn black and white lichen spots it may be necessary to extend the dwell time of Essential Driveway Cleaner to up to 4 hours or overnight where necessary, before power washing off. To achieve perfect results on aged, stubborn black and white lichen spots, test a small area to ascertain the required dwell time necessary to remove the marks – then follow the instructions above. 2 to 3 applications may be needed. Please note: The cleaner contains a chlorine-type agent as an active ingredient and will stain fabrics and sensitive materials. Take special care to avoid contact with fabrics and tarmac during application. The fluid might cause slight lightening of some surfaces – always try the product in an inconspicuous area before use. Coverage: Up to 50m2 per 5L when diluted 1:1. Coverage varies depending on surface contamination. Pack of 2.
