What ever you use DON'T use TeeCut or any abrasive cleaner. It looks great for a wee while but the paint has lots of micro scores in it that fill with soot and you have to teecut again and in no time there's no paint. Magnasol (spelling?) and water wash early, don't wait until it really needs it, if you need a one off shine, wd40 rags and elbow grease.
