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

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

I used this on my off-white porcelain patio slabs. It removed the heavy rust stains easily. It turns dark purple, goes a bit jelly-like then rinses away like magic. A few paler stains are still there but considering how the product performed on the worst stains, maybe they're caused by something else.

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

Absolutely brilliant stuff. Used this on my patio which had stained after dropping lawn feed on it. Applied this stuff left for 15 to 20 mins. It turns purple then just jet wash off. Job done. Highly recommend.

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.

This worked on my natural stone patio where planter legs had left small rust marks. I used two applications using a toothbrush to apply and the marks have completely gone.

Rust marks on our garden wall from two plaques disappeared with one application of this product. I would definitely recommend it.
