Is your patio, deck, or driveway looking green and grimy? Blast Patio Pro is the easy solution. It's a powerful 'spray and leave' formula – you just spray it on dampened dirty surfaces (patios, paths, decking, driveways, even rooftops) and let it work. No scrubbing or pressure washing needed! It breaks down mould, mildew, algae, lichen, and general dirt. The rain and wind will eventually wash it away, leaving your surfaces looking much cleaner. It's non-acidic and non-abrasive, so it's safe for most materials. A 1-litre bottle goes a long way. Made right here in the UK. Reclaim your outdoor space from the green stuff without back-breaking work!
