LTP Ferrex Iron Stain Remover & Stone Cleaner| removes Rust outbreaks, Rust discolouration & Cement Mortar Stains from Ferrous Hard Stones (5 Litre)

We had rust spots on our resin driveway for the past 2 years. This comes from the natural iron in the stone. I bought this on the off-chance it would work and it has made such a difference! Took a couple of attempts to find what worked but I went with a 1-2 parts dilution in a 1ltr pressure sprayer. I sprayed the spots when the sun was on it and after a few light sprays (no scrubbing) it removed all of the stains after a day or two. We had about 15-20 of them across the front and back garden. Well worth the money considering it worked and I still have half the bottle left.

I had Indian stone paving laid last summer. As with this natural stone, you're told sometimes that due to iron deposits you can get some orange staining which we had a little in parts. We were told to wait until this summer to see what comes through before sealing. It was annoying but not much really for anyone else to notice.Then, after putting iron sulphate on the grass, the little trickle of liquid in the watering can spilt on the paving and the next day there was orange everywhere!I'll be honest I was angry with myself and thought I'd ruined the paving.I bought this, tried a weak mixture in a small area and the next day it had cleared up. Still wasn't sure if that was just luck or my eyes deceiving me so tried the bigger area and the next day, after a medium pressure wash, the majority was gone.Absolutely brilliant product and would definitely recommend. Start with a low dosage first. I applied with a small paint brush and tried to cover a wider area so it blended it. Still needs a few touch ups but the difference is amazing

Did seem to get out the rust marks, but discoloured the paving slabs. Used on natural grey sandstone. Really darkened some of the stones, dislike following all the instructions, and also trialed on an off cut and that didn’t change colour

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.

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!

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

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

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.
