    Can anyone recommend a product to remove iron sulphate or fertiliser stains from concrete?
    There was nothing specific in woodies or B&Q and normal patio/drive cleaner won't even touch it.

    Unfortunately nothing will remove that bar removing a few mil of top surface. I've a few areas where I spilled lawn weed and feed and nothing helped clear it. I'd happily be proven wrong mind you.

    There are products that deal with rust (e.g. one of the Stain Devils, or HG Rust Remover, or some Rust Remover products Lidl sells from time to time), they might work, but no guarantees. Another thing that could work, if you can still find it, is toothpaste containing titanium (the whitening toothpastes used to have it, a few years ago). When you apply it, it reacts with the sunlight to remove rust stains.

    I've found this to be excellent at getting stains from stone and concrete:
