Hi. I installed a well for irrigation along with an iron removal solution but - while I was getting the concentration correct - I got some light brown rust staining on my grey pavers. I have tried a product called Iron Out which did help with the staining but seemed to bleach the grey out of the pavers (and they look blotchy);

.

I am wondering if anyone has any advice for products/techniques to get the brown rust stains out while preserving the grey color of the pavers.

Any advice is appreciated.

Thanks!
