Did not take out the heavy algae stains I put it on neat and left it a while to work in and even agitated to work it in, pressure washed off stains still there. Certainly made the concrete pointing fizz
Worked very well, very pleased with the service at Byfleet store
Wouldn’t say it’s brilliant in fact it didn’t move the paint of my patio
Only just acidic compared to former varieties of brick cleaner. Certainly not recommended for blobs or spills of mortar or cement on brickwork or paving. Watered down brick acid thanks to UK H&S
Made a bit of a mess with the bricks due to the weather, got this and the eye and hand protection, wet the bricks and then brushed on neat and it cleaned them up perfect.
I was pleasantly surprised how well this worked. I have a couple more patches to deal with.
Great product works well on grime and cement matks
Didn’t completely remove the cement from the tarmac drive.
Not effective at all, complete waste of money! :-/
This didn’t do a thing , I tried half and half and no water what’s so ever and I didn’t make any progress, I have cement makes on slabs and there still there .
Done what it says on the tin slabs have come up brilliantly delighted with product
Good stuff,make sure you don’t leave it to wash off to long,as it can go a nil white
Worked very well on heavily oxidized flag stones!.
A very good item for cleaning aged gravestones that have deteriorated with age
Weak as urine, will buy hydrochloric acid and dilute to suit the job in hand
Does the job as intended. Good product
That's the driveway cleared in time for autumn when the falling leaves will make it dirty again!
Cleaned bricks effortlessly after repointing. Strong stuff - gloves essential.
One of the better brick and masonry cleaners works well but gloves and goggles are required.
Didnt have the product i wanted, but the staff were very helpful and informed me this product wpuld do the job and it absolutely did. I ended up using a pressure washer and thatbhelped get rid of thebblack spots on my patio
