LTP Rust Stain Remover - Non-caustic formula (1L)

First off I tried all the YouTube options to remove rust from my paving slabs. Not one worked. Acids, bleaches and assorted household products....not one made a difference. This one however worked so well I have no rust marks left. On application it turns dark purple (great I thought complimentary rust and pickled beetroot...oh joy). The smell was truly awful and not for the nasally sensitive. However once rinsed as the instructions say...no purple and no rust. Brilliant.

Great product, used for rust stains on porcelain patio. Used an empty spray bottle to use it, made it go a lot further. Sprayed on the rust stain, waited 15 minutes till it went purple then rinsed off. Easy as that

This product worked well on my external porcelain paving that had rust stains from the kids trampoline.

Omg this product is amazing so easy to use removed rust mark on my porcelain patio would definitely recommend worth every penny

As this is non caustic I thought I'd try this on my vinyl kitchen floor.It did start to remove the rust stain and seemed fine so I gave it a second application and it reduced the stain quite a bit. Sadly I noticed the start of discolouration and fading on the floor so I had to stop.Thankfully the pattern covers it and I stopped soon enough.So it does help but I would warn against using this on anything other than stated on the bottle.

Bought this product because it purported to do exactly what I needed it to do - clear rust stains off my pavers. I applied it exactly how I should per the bottle instructions. Left it 15 minutes. The product did go purple as it said it would as it “reacts with the rust staining” Washed it off and the rust staining was there as strong as it was beforehand. The product left behind done purple staining on the pavers which took bleached water and hard scrubbing to get off. Total waste of money for me. I would not recommend this product at all. It has an awful odour too. Fortunately Amazon were great and offered a full refund upon returning the product to them free of charge.

It isn't often I don't se and review a product immediately, but a couple of days ago I spilled Miracle Grow 4in 1 lawn fertiliser on our only 6 week old concrete slabbed path. She who must be obeyed was not very happy with the resulting big brown stain and despite her best efforts with various cleaning agents the stain would not budge. This stuff did the job! Follow, the instructions, don't be phased by it turning bright purple, and brush off with hot water followed by a good rinse with the hose. Saved my bacon lol. Just be aware 250ml is only about enough for 2 x 600mm squared slabs.

Works well on rust stained porcelain - tried everything else on google but this works !
