The Patio Cleaner That Actually Works: Restore Any Surface in ~60 Minutes
If your patio is speckled with black spot, slimy with algae, or just looks dull no matter how hard you scrub, you don’t need a pressure washer—you need the right patio cleaner. Here’s how HR Total Power Clean gets porcelain, sandstone, limestone and block paving looking new again in about an hour.
Why patios look dirty (even after you’ve cleaned)
Black spot (lichen) anchors into the pores of stone—jet-washing the surface doesn’t touch the roots.
Green algae & moss create a slippery film that returns quickly if you only rinse.
Grease, BBQ spills and leaf tannins bond to the surface and resist household detergents.
HR Total Power Clean breaks the bond, dissolves the growth and lifts the contamination so it rinses clean—without blasting your pointing.

Fast method (no jet-wash required)
- Wet & protect – lightly pre-wet the patio and shield nearby plants.
- Apply – dilute 1:4–1:10 depending on how bad it is. Spread with a watering can or sprayer.
- Agitate & dwell – brush in and let it work 20–45 mins (keep damp).
- Rinse thoroughly – hose or buckets of water. Repeat on severe black spot if needed.
Typical 5L coverage (after dilution): 150–250 m² depending on porosity and contamination.
Common mistakes (and how to avoid them)
Over-reliance on pressure washing – it can erode pointing and doesn’t kill the spores.
Bleach on natural stone – risks etching or light patches.
No sealer after cleaning – clean patios re-soil faster without protection.
For long-lasting results, consider sealing once dry:
Rich, enhanced look: HR Colour Enhancer
Natural, un-enhanced finish: HR Total Finish Matt
