[size=12]I do more or less what Claudia is talking about, although it always requires several applications to clean a piece, and 8 hours between applications is plenty of time for it to do whatever it's going to. I do it to avoid clean-up issues and for space reasons. I'm not a dealer, so I don't have volumes to process, and I can afford to take my time. Personally, when it comes to rust, I use fine grade steel wool, which any hardware store should sell. A lot of people on here don't want to use any abrasives of any kind, so I may be in the minority. I haven't had scratching issues with it, nor have I seen it discoloring nor coating the iron. Avoid brass.[/size]
