Default Rust on Pavers

Anyone know of a good product for removing rust stains from pavers? I have four rust spots from the feet of a metal fire pit. I have heard that some cleaners are very aggressive and will damage the pavers. Thanks in advance!

CLR or products which contain muratic or oxalic acid. Begin diluted, work up if have to.
BUT, this is a time to try small amounts on not so obvious places. No one knows how the stains in the rocks will react.
I think I might try the pressure washer first.

Spray the F9 direct on the pavers, driveway, bricks, vinyl siding. You could probably remove rust from gelcoat.

Same acid as used in swimming pool. Sulfuric. Never hurt my pavers or the pool cap brick. Learned last year also worked great to remove rust from King Starboard.

Thanks guys! I knew I would get good answers here! Although I am leary of pressure washing my pavers. My dad has his pavers cleaned a few years ago and he ended up with a bunch of them settling. The guy used a pressure washer and I guess he did a little too much "cleaning".

You won't be able to pressure wash a rust stain. Muratic or sulfuric acid, buy it at a pool supply store and start pretty diluted. Or get The Works toilet bowl cleaner.

This. Use something with oxalic acid or buy a container of it off Ebay. It's also called Wood Cleaner but hard to find in stores. I use it for rust removal on motorcycle restorations.
