SmartSealPatio Cleaner Xtreme - Powerful Easy To Apply Patio Cleaner Fluid - Highly Concentrated Patio Black Spot Remover and Paving Slab Cleaner - Eradicate Stubborn Patio Black Spots (3 x 5 Litre)

Why did you choose this product over others?:This is my third year buying this product for my indian Sandstone paving. I spray it on leave a couple of hours and wash off with a hose. Always comes up spotless and no need for a pressure washer which can damage the stone. Only difference i noticed this year is the smell. The chlorine is very overwhelming and as an asthma sufferer it was a bit chocking. I thought i had mixed it wrong but no just as the package suggest so i assume it;s a different formula. Still works a treat but keep your windows closed and use plenty of water after to wash it.

Have ordered this stuff twice recently and can say it has saved my patio and front path. Alot better than expected. Used it a few times on front path with a pressure washer set on highest pressure setting and has Brought it back to nearly new. Anyone who buys this your path/patio may new cleaning a few times but be persistent and this does the job. Will be ordering for 3rd time very soon to do my path in the garden. Saved ££££'s in replacing old path and patio. Highly recommend 👍

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

Really pleased with this product.Have used numerous other patio cleaners before and they haven’t really touched it.I dampened the surface as as per instructions. Applied the liquid 50-50 with a sprinkling water can.Because my slabs are bevelled , the dirt sits in between the ridges so IScrubbed over each slab with a wire brush. ( purchased on Amazon - see review.) as soon as I applied it…I then left it for 1 1/2 - two hours and then rinsed off with a hose pipe with the spray attachment.Unfortunately, I don’t have a before and afterBut I attended a during and after..Delighted with the results. The only thing it did not remove , was a few black spots, but I was expecting that.If it helps how much to use - I purchased 4 containers and used one and a half for the area that you see.

Dry good stuff does the job my driveway is looking very clean now.

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

The product is very good

I used this product yesterday and I used it neat as described on the bottle.I scrubbed the paving with a deck brush and left it for two hours as recommendedI then rinsed the paving and I was very pleased with the result, all the black spotting has gone andthe paving is restored.I do not feel qualified to give 5 stars hence my 4 stars
