    Default Removing rust from concrete

    I have rust strains on concrete from where my fire drum (truck brake drums stacked 3 high) has been sitting.

    This is something I've never had to do before so I'm assuming a scrubbing brush and chemicals.
    Will CLR (I've never used the stuff) do the trick or do I need acid - if I need acid what ratio do I dilute it to?
    Is there anything else available other than those two?
    Cheers
    Paul
