Hi guys looking for some advice here, roughcasted a dormer on a roof with white enewall top coat and dashed with white Nordic chips last week. Had to leave the job after finished it and left my labourer to clear up any way he cleared up but didn't wash the brand new leadwork down [says he forgot an expensive forget for me about a grand worth of lead]does any body know of any product that will take the white marks off the leadwork without damaging the lead. Cheers stuart.
