Patio Cleaning: The Ultimate DIY Guide (Fast, Safe & Stone-Friendly)
Patio cleaning doesn’t need a whole weekend or a roaring jet washer. Imagine stepping outside tomorrow to clean, even slabs, richer colour and no slippery algae after about an hour of simple work. See what’s possible with the method below and the pro-grade cleaner our technicians use every day.
Stop Scrubbing. Start Winning the Patio Cleaning Battle.
You’ve tried it all: pressure washing every inch, supermarket “mould removers”, even bleach. The algae comes back, black spot speckles remain, and the pointing takes a hammering. We hear this weekly. The truth is: most products wipe the top, not the root. That’s why your patio still looks tired and why cleaning garden slabs often feels like a losing game.
Here’s the good news: with HR Total Power Clean you get a stone-safe formula engineered for algae, lichen/black spot, grease and tannin stains. It cleans deeply (not just cosmetically), works across limestone, sandstone, slate, travertine, porcelain, block paving, granite, concrete, and even helps you freshen cobbles, steps, stone walls and rendered (renda) walls. Instead of paying a pro £100s to “have a go”, you can achieve professional results yourself in about an hour without blasting pointing or risking etching natural stone while cleaning garden slabs.
