One Chem 2 x 5 Litre Ready To Use Spray and Leave with added Long Hose Trigger Spray - Fencing Patio Decking Driveway - Green Algae and Mould Killer

Not had chance to use this yet though I've had it before at my previous address so I can comment on how great this is. Really good cleaning power clears moss and all that green mouldy stuff that is hard to get off with normal cleaning methods. Spray functioning is perfect and so fast it really shifts anything in its path. Such good quality and value for money.

The actual solution worked really well clearing the green mould on my fence within a few days. The only thing i would criticise is the free spray gun adaptor. It wasn’t really up to the job so I used a spray bottle I already had to apply it. All in all a good product at a cheap price. I would buy again in future.

I purchased this to clean up my old decking which was more or less green all over. I did not have high expectations as my decking is now old and I didn't treat it last year.As soon as the solution dried I could see a difference and 24 hours later the decking looked the cleanest it has in years and is now ready for staining.Unfortunately I forgot to take a picture before the cleaning treatment.I really liked that it was ready to use.The only slight negative would be the trigger hose it isn't great, but does work.I have only tried on decking but have plenty left to use on my path and front paved garden.

Sprayer didn't work, decanted into a smaller bottle but a real pain as needed to do a large area, definitely buy a sprayer at the same time as ordering hopefully the product works better than the sprayer, update on the product cleared heavy algae really well but patchy due to the sprayer I will buy again however

The spray worked really well on my son’s fence and shed. The sprayer is a bit femur but it does its job. All in all it’s great value and quality product.

Sprayed the product on to several fence panels that were covered in green algie. The instructions said that it would take 2 weeks to completely resolve through green, but it cleared completely in 6 days. No scrubbing needed and I painted it the next day. Really super results. Sprayedit onto so green on the patio, and that's cleared nicely too. Great product, and I've only used half of one bottle. The sprayer is great too.

The fluid is brilliant made such a difference already and after only one rain downpour.Knocked off a star as the pump to apply the fluid stopped working after using half of the fluid so will now have to buy another one to apply the rest

It’s the spray did not work in the bottle but also it was very ineffective
