Ok, I am not talking about Florida winters, but winter where there is snow, ice, and cold. Where do you wash your car, if at all? Where I am at it is still not bad, temperature between 5 and 20 celsius. In the winter it can be down to -30, or up to 10 celsius. Surely one cannot hand wash because of frost bit. Is hot water ok? I am thinking power wash is ok as long as we don't use their soap. I think that stuff will strip off the wax? I have 3 layers of Zaino and would hate to have that come off. Would the hot water do any harm to the wax?
