Very expensive. I wanted to remove staining on my decking. Tried this and it worked, but calculated I'd need about a hundred bottles. Researched the active ingredient, which it turns out is Oxalic Acid. Sourced some oxalic acid from an online chemical supplier for £5 and was able to make five litres. My tip if you've got a large area is do what I did.

We had marks on the cream carpet in our caravan going back 13 years, when we had a flood and the metal studs under the sofas left bad rust marks. I recently saw this stain remover and thought at the price it was worth trying. Amazingly the rust is now completely gone! It's unusual to find a product which does what it promises. The only problem I had was in finding the places where the stains had been!

Product removed about 80% of rust stain from my natural stone path which was caused by rusty bolts from the feet of garden furniture. This was acceptable to me as the staining had been there for a few years and what is now left is hardly noticeable.

This cream took some work, but eventually bought our old scratched tables up looking like new. Still working on an old ring stain on a walnut cabinet, but already after two applications its not so noticeable. Definitely would recommend, its much cheaper than new tables.

I had some nasty rust stains on some dinghy sails as a consequence of storing wet/damp on metal hangars. Sails were good condition but thought I had ruined them as could not be seen in public without!! Had tried the usual household cleaners , but did not budge. For £3.70 I thought I would give this stuff a try as nothing much to lose...it was miraculous!! On application it looks as if it is no going to do anything, look a few minutes later and the rust stains start to disappear and within an hour or so they had completely vanished. So a £3.70 investment has saved me £100's of pounds. Brilliant

I used this on my much loved cream denim jacket. I’d forgotten I’d put a few of my put iron pills in my pocket when on holiday and I washed the jacket . When it came out of the washing machine it was covered in dark orange rust all over the pocket and front. Who knew a tiny iron pill held all that iron.I used white wine vinegar, bicarbonate of soda my usual stain remover Wenco that removes everything usually! I put it H G on the the jacket in desperation and within minutes it had disappeared. So relieved ! Don’t hesitate buy it this is an amazing rust remover.

I used this to remove several large rust stains on a flag. Having tried many other online sonohtiins including white vinegar and lemon juice and salt to no effect.I poured a small amount of this into the fabric and you litteraly can see the rust disappearing before your eyes.

I had rusty tiles in the bathroom floor and in the shower. It had been there for years - it was really thick rust and unsightly, I never thought I would be able to remove it. Regular cleaning products didn’t work.This product got rid of all 100% of the rust on the floor tiles, left the product on it and an hour later it just came off really easily. It got rid 95% of the rust on the shower wall tiles. Because it’s liquid the products just runs down the wall and didn’t stay on the rusty part for very long, but it still got rid of most of it. It’s an excellent product.

I bought this product to deal with mysterious orange stains on laundry. The stains looked more like orange felt tip pen, and were completely impervious to bleach. I didn't really think they could be rust, but as rust is just about the most difficult stain to get rid of, thought I would try this. Magic, it completely worked.

I got rust on my favourite white linen shirt and after trying all the tips online to get rid of the very prominent stain I ended up looking for it’s replacement until I saw this product, I followed the very simple instructions and voila the rust disappeared in front of my eyes, I’m absolutely thrilled and wouldn’t hesitate to give 5 stars
