    How would you approach these? I tried non acid carpet rust remover with no luck.
    The "idiot gardner" (who I think was the husband as he sat there looking adequately subdued) spilled fertilizer on the pavers and didn't sweep it up or rinse it off.. @Mikey P 20180411_111028.jpg

    I was thinking maybe making oxalic acid paste?

    or am I on wrong track?

    its on quite a few over an area about 15ft x 25ft they're not worried about the current pitting or scratches just the staining

    You are probably fighting a chemical in the fertilizer, so it is not just a rust stain. If it is yard fertilizer they may contain phosphates and ammonium nitrates. How would you fight a urine stain on limestone? Might have to be your thought process not rust.

    Looks as honed as can be, try Wink or what ever you use on fabric

    If that process some how dulls it even more, take some 200 grit wet sand paper and feather it in

    Sounds like it goes very deep. An abrasive pad like a Hone pad, or 7" 200 grit Revolution pad with water may help remove some material to get a little deeper. I'm not saying leave dipping or going too aggressive; just spend a good 30 seconds to a minute on it. Then try your chem products. Of course I will recommend using STONE PRO Stone and Glass scrub to help agitate an bring out rust discoloration. Even a 3m green/blue pad with the Stone Scrub has removed rust left from rod iron chairs and tables from Travertine for me.[​IMG]

    Dan, why do you think it is rust, rather than an organic stain?

    its an amazing property they do weddings and corporate retreats, they call me several times a year for carpets if a wedding gets messy. Pulled multiple red wine stains out of beige wall to wall wool

    So the stone looks tumbled and dull; why not use Barkeeper’s friend and a good scrub brush? It won’t eat the stone like some acids, but it would certainly dull a shiny finish.

    If the stone has a sheen, you could always just use a foam disk and some travertine polish, or just good old car polishing compound. You’d buff it up a little, to match the area.

    If this is rust, klenzstone will take it out or off in a few minutes.
