Rust Stain Remover - Fast Acting Non-caustic Formula. Specially formulated to eliminate surface rust stains from various outdoor surfaces (250 ml)

We had a rust stain left by a rusting metal plant pot on our Indian stone patio. I wasn’t sure what to do about it, but after some research I found this product. It’s very easy to use and removed the stain completely. Amazing product and well worth the money. My patio now looks as good as new. You only need to use a very small amount, so the small bottle is more than adequate. It works very quickly and you can actually see it working as it turns purple! I used the lid to pour some of the liquid into first as it was easier to control how much I wanted to apply and to be more exact in the placement. Maybe a very small spray bottle would be a good idea.

I was dubious about this product , but it does what it says on the tin. Rust stains are removed quite easily once its left to do its work then washed down with a jet wash. Stubborn areas just give it a second wash and they come up like new. Excellent product

Works really well on light rust. Heavy rust takes a few applications

Have tried on a few small patches of rust stain on our porcelain tile patio. You can see it’s working as it turns a deep purple colour and within 15 minutes the stains have disappeared. One slightly larger and deeper mark needed a second application to fully get rid of the stain but it worked a treat.

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.

This product has a strong odour - turned purple has stated - but dos not remove rust - even though I tried twice . Only thing that will happen is a colour change..

Surprisingly good. Had some bad / heavy rust stains on a tile floor. Toughest stains had to be repeated twice, but fully removed the rust like it was never there. No damage to tiles whatsoever.

Excellent product does exactly what is says on the bottle, stain removed in 15 minutes with no rubbing or scrubbing required!!
