Q: WILL IT REMOVE RUST MARKS
A: Patio Cleaner Xtreme will NOT remove rust stains. To remove rust stains, you woud need to use the rust remover.
Q: Hi, what type of spray can used to apply extreme patio cleaner, brick and roof cleaners. Do they require virgin seals. Thank you
A: We woud normally recommend using a watering can to apply the Patio Cleaner Xtreme as it is quite corrosive to any seals in a sprayer. If you want to use a sprayer it is important to flush the sprayer through with water immediately after use to stop the seals degrading.
Q: Hi, we have indian sandstone and a car oil stain. What would be best for this? Zoe
A: The Patio Cleaner Xtreme will only clean dirt, grime and most forms of green organic growth. It will NOT remove oil stains. We do not sell an oil remover for use on sandstone. The only product we have that may help is the driveway cleaner. This will remove light biodegradable oil residues as well as traffic film and dirt, dust from cars.

Not one to leave reviews, but this product deserves it! I spent a couple of hours researching online and saw many saying to spray and leave for a couple of weeks, but I wanted something more instant and saw this and the reviews. I have a porcelain patio and after 8 years, it was heavily stained with algae, lichen and also bits of black grit that bounce off a flat roof. Despite annual jet washing, most of this remained. I jet washed first, then sprayed this on with a 1:1 mix using my garden pump sprayer. By the time I had gone all the way around with 15 litres of the diluted solution, I gave it a once over with a broom and could see most of the stains had vanished. Left it for about 2 hours in total and jet washed it off. The tiles are looking like new and make those indoors, as we have them running throughout, now look dirty by comparison ?. I probably didn't need to jet wash the tiles down first, as this made light work of the grime. Still have just under half the solution left for next time ?
Was looking for ages for a suitable cleaning product for my Indian sandstone patio and came across these guys and the reviews were brilliant so took a punt. I am so glad I did. The patio looks like new. There is still a few stubborn slabs that could do with a 2nd coating which I will do later down the line. But I will be a repeat customer for sure. Thank you very much I am delighted
Just used the patio cleaner on all hard surfaces. Very impressed with the pavers . Highly recommend
