Algon Organic Path and Patio Cleaner Concentrate 2.5l

This stuff is magic, so really to use and gets rid of the green algae. Need to leave it a few days for a proper result, but takes all the hard work out, of doing it my hand.

So impressed with this on our driveway gate. Worked in approx three days - see photos!

Mainly worked on patio tiles using a spray can. Green algae did eventually die and as per other feedback it took around 2 weeks for noticeable results. Fortunately we had a dry period with no rain. However the black lichen spots remain, not sure if this product is supposed to get rid of them. Smells like strong vinegar if you get it on your fingers.

This really worked well on both my garden fencing & stone patio. But it didn't work fast, takes at least 3 weeks & on fencing in particular turned the green algae very white, which lasted for another few weeks before leaving a much cleaner result. Expect 5-6wks but my results were excellent after this time. Will use again & it's a bonus it's pet friendly.

Was easy to use as we purchased a hand pump sprayer to put it in...results are not as good as we had expected after reading other reviews...However it is an old patio and well loved by visiting hedgehogs that do leave poop!!.As its wildlife friendly we are going to try again in early summer

I use this every year on my patio and side path. This year everything was greener than usual! I have used this in a watering can with spray bar which works but last year I bought a hand spray pump and this makes delivering the solution easier on my back. It also enables a more even coating across the slabs. It effectively removes the green algae, and other built up dirt from the slabs. Each day you see them a little bit clearer. I do find though that the black algae is more stubborn and has remained. I hadn’t realised this Can be used on most surfaces, so this year I also sprayed it along my green conservatory window & roof edge. Hopefully it will clear this off so cleaning with soapy water is easier. We have a lot of wildlife in our small garden plus small pets so it is good to know that once dried they are all safe to walk on it. As it says be careful along edges of flower beds as the strong vinegar solution withers the greenery if it touches it. I always weed the patio and remove pots etc off it a couple of days before so the insects which live beneath them move away before I apply the solution. I do not want to cause any harm to them & would think it may burn if sprayed onto them. Every life matters.

Amazing for cleaning a filthy patio! I used this about two weeks ago, forgetting how good it actually was. I couldn’t believe my eyes when I took a good look at the patio this morning. It was cleaner than it’s been in years & that even includes after jet washing. I’ve now used it on the driveway in the hopes it will clean that too. I suspect it will take a few applications though. It’s cheap enough though and there’s no nasties in it - plus it doesn’t take up half your day & get you filthy like jet washing does!

This product is 100% NOT safe for pets! After using it all of our dogs developed extreme sickness & diarrhoea!! We followed the instructions to the letter. We even didn’t let the dogs out for 24 hours into the garden (not on the instructions), they get it on their paws and when they must lick them they digest a small amount! Seriously if you have pets be very careful! One of the dogs ended up at the vets as he was pooing blood! Ended up on a treatment to replace the lining on his stomach!!!

Le produit ne semble pas très efficace. Passé deux fois sur la terrasse elle reste toujours noircie. A voir si cela facilite le passage du carscher
