Patio Black Spot Remover for Block Paving is specially formulated to remove stubborn black staining from block paved driveways, patios and garden paths. Designed to penetrate deep into the surface, it breaks down built up discolouration and grime that develops over time, helping restore the original colour and appearance of your paving.
Unlike general patio cleaners, this targeted treatment reduces the need for aggressive pressure washing, helping protect jointing sand and the overall structure of block paving. The biodegradable, acid free formula is safe to rinse into lawns and flower beds and is safe for pets once washed off. Ideal for larger areas, this 4L size provides effective coverage with reliable, long lasting results.
