How Do You Clean Indian Sandstone?
It’s a question we hear every day:
“What’s the best way to clean my sandstone patio?”
The answer? Put down the pressure washer.
High-pressure cleaning might seem like the easy fix, but over time, it damages the surface, causing delamination and cracking - especially when using petrol or diesel-powered washers with a PSI above 1800.
Instead, trust a product that does the work for you
Try - Patio Black Spot Remover for cleaning Indian Sandstone
Patio Black Spot Remover is designed specifically to tackle what sandstone suffers from most:
✅ Black lichen spots
✅ Green algae
✅ Deep ingrained dirt
✅ Dull, tired stone colour
Spray it on, and within 10 minutes, green algae will vanish. Leave it on for the full two hours, and watch your patio transform. You’ll see the natural colour restored without scrubbing or aggressive pressure washing.
Older patios may need a second application, but most sandstone surfaces—especially those laid within the last 6–7 years—respond beautifully with just one treatment.
What About Maintenance?
Good news—you don’t need to do this every year. Just apply Patio Black Spot Preventer 11–12 months after your initial clean. It’s a spray-and-leave treatment that stops black and white spots and algae from returning, saving you time and hassle.
Why Does Sandstone Stain So Easily?
Because it’s so porous, sandstone naturally absorbs water—and with it, the organic spores in the environment. Over time, these spores feed off the minerals in the stone (particularly iron), leading to unsightly black staining that can’t be removed with pressure washing alone.
Keep Your Sandstone Looking Like New
Whether you’re restoring an old patio or protecting a new one, The Patio Black Spot Removal Company has the products—and expertise—to help. With the right maintenance plan, your Indian sandstone patio will look as fresh as the day it was laid, year after year.
