    Any advice on how to remove concrete stains from a tarmac drive? It's actually only the water from washing out the mixer after mixing concrete but has stained the driveway quite badly. Any advice is greatly appreciated.

    This happened to me recently, during a refurb. Its hard to get rid completely.
    Powerwash was our solution but it can still be seen a bit when dry.

    Try brick acid it desolves cement stains but I dont think it affects tarmac.
