“Brilliant product. It has totally transformed my Indian sandstone patio removing stubborn black spot which has persisted for years. The patio looks almost new. Easy to use with garden sprayer, just follow the instructions. Wear old clothing as contact will bleach your trouser legs. I have already purchased some more. Highly recommended product.”
“Have been looking for something that lives up to it's hype - and this killed it!! Patio has never looked better - easy to apply, leave for a couple of hours and hose/brush off - excellent results.”
