LTPFerrex Iron Stain Remover & Stone Cleaner| removes Rust outbreaks, Rust discolouration & Cement Mortar Stains from Ferrous Hard Stones (1 Litre)

I suspect brick acid had been used to clean some stains off my patio (they'd tried numerous times to remove them) left by a company who installed new doors for us. Unfortunately over a few days, brown stains emerged which I thought might be rust but I couldn't see any rust near them. I later learnt it comes from within the sandstone. I had visions of having to replace the affected flags but I thought I would give this a punt. I used 3:1 on the least severe and 2:1 on one stone which was quite bad. After 3 hours, I washed it off thoroughly and the stains are all gone. I am very impressed with the results. It's not often a product delivers perfectly on what it promises so easily so I am very happy!

It removed all the rust iron stains from our 8 month old indian stone patio flags.I watched the video before purchase,worked as shown.Would definately reccomend.

Worked better than other things I tried. Would use again

I read instructions and watched videos.i did a diluted mix at first.must say I wasn't impressed.i was doing it on bad rust spots off my patio set.so I put it on neat doing spot treatment also my pavers were wet as it had been raining.after application I just left it to see what happened.WOW no more rust spots . seriously I'm impressed.ive tried all types of removal and acid was my last resort as I know it leaves funny colours on Indian sandstone.i thought I was going to have to buy the other rust remover they do but after just dabbing it on neat with a paint brush it's worked a treat .also it's left no marks whatsoever maybe because my pavers where wet to begin with.i recommend this as it has worked it's a little pricey if you have large areas but as a spot treatment it's smashed it.

Good product but didn't remove all of the rust on my indian sandstone. Will try again with a stronger solution.

Had my doubts this would work after an acid treatment was applied to our sandstone pavers. The stains were pretty bad.Applied as instructed with a 1-2 dilution and with a paint brush. Allowed to sit for six hours and then rinsed off. Some pavers needed a second treatment but it all came out.When applying, make sure to apply to the whole paver and not just rust patches otherwise you get uneven colouring.But as said before, works a treat.

The media could not be loaded. First things first. I'm cannot comment on this products rust removal. This review is based on cement stain removal only.It's diabolical, bordering on misleading. I used a 1:1 ratio and after applying with a sprayer I got in my hands and knees and agitated all stains with a stiff nylon brush. It appeared to do something, as the stained areas kind of fizzed up white, so it looked promising. I waited the 6 hours as directed and rinsed off. Absolutely none of the stains have been removed. I then tried with a jetwash. And still nothing has budged!I cannot comment on any discoloration or anything like that as the stones are still wet. But it doesn't look to have caused any issues.£20 and 6 hours wasted do not buy this if you are looking to only remove cement stains.

With these things you always have your doubts until you try it. This removed all iron stains on my Indian stone patio slabs with very little effort. I would definitely recommend this product and dread to think what state the staining is on those who claim this stuff failed
