SmartSeal Patio Cleaner Xtreme - Powerful Easy To Apply Patio Cleaner Fluid - Highly Concentrated Patio Black Spot Remover and Paving Slab Cleaner - Eradicate Stubborn Patio Black Spots (5 Litres)

This product is perfect to help get rid of the mould and ring stains left by the garden pots on your patio. We could not believe how well it worked for us, the patio is so clean you could eat your dinner off it. The only thing I would advise and that is use a face mask as the smell is quite strong.

Amazing and effortless product. I applied using a watering can on an Indian Sandstone patio. Looked like new within a few hours.

Had a patio with 6 years grime and algae. Two applications did the job. A bit pricy which was made worse because I did not have the equipment to use as sparsely as recommended. Never-the-less easy to use. Will use again in 6 years time

This stuff isn’t cheap, but it’s the only stuff that worked for me. It absolutely cleaned up our patio Flagstones and they look amazing. So glad I found something that does work now.

Excellent stuff. The mould on my porcelain paving just disappeared in minutes so I was able to wash away the residue quickly.

Thought I would try this and was very impressed with the results! Much less effort and mess than pressure washing. Left on for just over an hour. It is expensive but well worth it, would definitely use again and recommend to others.

We had black spot on our Patio and the Liquid was fantastic. It didn’t get rid of it completely but it improved a lot. Would recommend.

Great product so much better than Patio Magic which did not remove the black spots.
