Picked a Silver B this week and the tables have what looks like grease stains. I’ve tried degreaser and steel wool. Some barkeepers friend as well. Not doing the trick. This is the first one I’ve done with these tables. Any tips on getting these clean? I’m also having trouble getting the control panel clean. Looks like it’s faded a bit. Even though it’s porcelain I can’t get seem to get it clean with degreaser and steel wool. Even tried some rubbing compound. Still seems faded. This is only my fifth restore on these and this one’s got me stumped. Any tips would be greatly appreciated. Thanks in advance
