How to you clean off and are of the wood stove to prepare for touch up paint. Is mineral spirits okay? I have a steel plate stove with buck Paint. THere seems to be some type of oily residue on top of the stove. (probably from the kids somehow) I can't get it off with water and I need to do some touch up paint on scratches... Not sure if mineral spirits will breack down the paint too much. Any tricks of the trade?
