    Rust stains on stone coping

    The builder left a piece of rebar on my stone coping and after some rain, there is a rust mark on the stone. Anyone have any ideas of how to get rid of this, or will it fade on its own?





    Thanks!

    Try undiluted lemon juice or vinegar and a stiff brush. If that doesn't work try some oxalic acid and a stiff brush.
