SmartSeal Rust Remover - 1L - Powerful Rust Remover for Metal, Stone, Porcelain, Concrete, Block Paving & Natural Stone. Fast Acting, Acid-Free Formula that Removes Spots & Stains from Rusting

Why did you choose this product over others?: Really good product, removed rust stains left by a calor bottle and iron chair marks on sandstone. Suggest you use gloves as it is very strong. Work on small areas at a time during dry weather. Keep agitating with a tooth brush, wipe off with wet rag. Use only clean water. Repeat as necessary.

It is a very small bottle for the price. Had rust marks on the new patio tired various of products and nothing work. This was my hail Mary. It removed the stain to my surprise. It was easy to use. Used a small amount and a brush to rub it in. Make sure you follow the instructions.

Cleaning power was brilliant. Even on my sandstone paving. Removed rust after minutes. Turns the rust purple then you simply rinse off. No stains left behind. Exspensive for the little tub but well worth the money. Really happy with the results

Tried this on rust stains on a concrete patio. It lightened some of the marks but didn’t fully remove them, even after two applications. Easy to apply and no damage to the surface, but performance was average. Might be better for lighter stains.

7 months ago a clown of a tradesman used an angle grinder on our wrought iron fence in the pouring rain, therefore completely ruining 2 parts of our brand new Indian sandstone patio with rust. After such a length of time, I wasn’t sure the product would work but it did a really good job. It has to be applied when the slabs are bone dry to work effectively. I scrubbed it by hand, leaving it for around 5 minutes and then thoroughly jet washed it off. It takes a lot of repeat rinsing. As you can see by the photo the difference it has made. It’s expensive and I have had to buy more to complete the job.

The metal Christmas tree stand left a large rust mark on our limestone floor. It was a very dark mark and didn't get fainter with normal washing. I searched on Amazon just to see if there was a rust removal product and found this. It worked brilliantly! The tile is very slightly lighter (probably taken out general dirt too) but not so you would immediately notice and nothing that detracts from a natural stone floor. Highly recommend.

I used this on concrete patio slabs that had a lot of rust staining and it took a couple of applications, but it did work. The only reason why I gave it 4 stars is because it is a bit expensive.

This is amazing stuff, I unfortunately had a few rust patches on my grey Indian tiles and used an acid rust remover. Well not knowing that would be a big no no for Indian tiles, it nearly ruined my own patio. The acid reacted and rusted everywhere and this stuff didn’t half work. Now the tiles will never look as new but at least they’re not an eyesore!
