    We run a Ryobi 524 HE and are based in the UK.
    We are having a problem keeping the steel between the metering roller and the water form roller clean.
    Tried cleaning with acid and then gum Arabic but no joy.
    Replaced metering and water form rollers but problem persists.
    It is not the whole steel roller that is inking up, only ink banding around certain areas but not allways the same spot.

    Any tips on desensitising the steel appreciated.

    we use a chrome roller cleaner and desensitizer everyday after we wash up. It works well.
