Pro-Kleen Patio Cleaner Mould and Algae Killer Ready to Use Simply Spray & Walk Away 5 Litres Patios, Fencing, Decking and Resin Driveways No Bleach or Acid

This product was useless, you might of just sprayed it with water. It ran out before we had finished doing the patio and you cannot see any difference. So disappointed!! I did not realise you had to wait for a few days to see the result, it has cleaned the green algae quite well. It doesn't go very far, so it's expensive.

Bought this to use as a pre treatment for my decking as I was going to jet wash and re-seal it. Can confidently say it made no difference and won't waste my money next time. Easy enought to use, and scrubbed in with a sweeping brush. Foamed up a bit and left it, but did nothing. Good job the jet wash sorted the green moss and staining right out.

Made the clean bits of my patio look cleaner, however it failed to remove any of the black spots. Administered it diluted as per instructions and left it for 3 days. Then put it on undiluted, 3 times, and left it for 3 days and just gone to give my patio a power wash and it hasn’t removed one black spots

I jet washed half of my patio, let it dry and put this on the other half. I left if for a few days which just dried it then I jet washed it. No difference to the original jet washed side without cleaner. There were a few marks I wanted rid of so put it back over the cleaned dry areas and nothing, left it another few days with no rain too. I did go over these marks with fairy liquid and a stiff brush then reset washed which worked better. I also tried this on my walls. Nothing. Unless over time it keeps mould and moss from re setting in I am yet to find out but my opinion is it’s not worth it. Your best spending you money on better stuff.

I cant say ive seen much difference, other than the odd dead weed . the flags n decking n tarmac that had been discoloured looks the same colour n just as dirty now. in the end after a couple of week i just had to scrub the surfaces clean. maybe if sprayed onto a clean surface it might stop stuff growing n discolouring in the first place? i dont think this should be described as a cleaner or something that u can just spray n come back to a difference.

After walking outside on a fine breeze-free day, gently hold a match box with fore finger and thumb of your left hand. Swiftly strike the match with your right hand along the coarse strip on the side of the matchbox, using a gentle sweeping and continuous motion. Now pick up the ten pound note and five pound note you have previously put near easy reach, overlaying them together. Hold them into the flame until the notes are alight. Lower them to the ground and ensure they are completely burned. You have saved the time otherwise buying this product and doing pretty much the same, but with the added benefit of avoiding spraying this product on your path or patio whilst wearing protective safety wear. Whichever route you choose, your algae will likely be the same based on my wasted time doing the latter.

Honestly i was 50/50 on a product that claims to do a similar job to using a power washer but without all the farting around and mess that i always get when power washing, I even purchased garden pump sprayer to do the job properly. The pump, brilliant, this stuff was a complete waste of money, I can't even say it had a bit of an effect I can not see a single bit of improvement, either I did it wrong, which is difficult for a spray and walk away product or my patio is beyond cleaning. This weekend I will mostly be using the power washer and regretting wasting my money

I've bought patio cleaner before but its had to be diluted so I was surprised when this came ready to use less work I thought I do think it should have come with a spray attachment so I could remove top and insert spray but it didn't so I decanted it into a spray bottle Sprayed fences and patio last night and nothing the algae is still there Not happy as my other brand worked brilliantly without need to get the power washer out I have half a bottle left so will try again when it gets warmer and see if there's a difference but I wouldnt recommend at this time sorry
