Smartseal Rust Remover - 1 Litre - Acid-Free Rust Stain Cleaner for Natural Stone, Concrete, Driveways & Patios - Safe & Easy to Use - No Damage to Surfaces

I had somehow managed to spray lawn feed and weed all over my patio and hadn't noticed. Returning from holiday a couple of weeks later I found the patio badly stained. I tried a acid cleaner but it didn't make any difference so I began to think I'd have to have the patio replaced. I did a on line search and found Smartseal Rust Remover so ordered a litre. I tried it as soon as it arrived and thankfully it worked, my slabs look great. Definitely recommend Smartseal Rust Remover.

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.

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

Repeated applications have slightly faded the rust stains but they are still very visible. Was hoping for better performance.

This completely sorted the fertiliser rust staining on my granite setts. Very pleased. Unfortunately it doesn't go very far on this type of surface so had to get more. 1 litre needed for every 5 sq m. Would go much further on flags I expect.

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.

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.
