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

Worked a treat, although the trigger sprayer gave up after a couple of mins. Decanted the rest into a watering can. Probably got less coverage but it worked really well as it was more concentrated poured compared to sprayed. Will buy again.

So far so good. Within 2-3 days, killed it all (no green) on mortar, wood and pavement. I might buy the concentrate (if available) next time. The hose took a while to "pressurise" and come down to the soray head so persevere? 🤷

Over night result excellent. Trigger for item no good. Transferred liquid into a detergent bottle and sprayed fence. Heavy algae disappeared over night to bare wood. Excellent

I'm not impressed with this algae remover I've used it 3 times now still no difference it doesn't do anything, waste of time. !!! I've read that some customers are saying that the trigger doesn't work to pump it out. !!! There is nothing wrong with it, all you have to do is make sure the trigger is lower than the top of the bottle before you press it, then let gravity do its work. !!!

I was a lot dubious about this product. So some of the great melted away in front of my eyes. Some I thought ok it’s not going to work! Bam 24 hours later it’s all gone! Only negative is I didn’t get enough of it! Easy to used with spray top.

Doesn’t do the job. 🤨

This worked very quick, removed the lighter algae off my fence, had to do second time for thicker algae, the reason for the 4 stars is the pump spray that comes with it doesn't work. Takes alot of pumping to get a little spray then packs up, had to transfer it to a spray bottle

This worked well at getting green algae off our rattan furniture that had set in over the colder/wetter months. Going to try it on our metal fencing at some point. Coverage is good. Easy to apply. Seems good value for money as plenty in the container and only used a small amount. Do follow the instructions for best results. Seems efficient and product matches the description. Would buy again. Thank you.
