I'd advise against wire brush,unless you will be using it only to remove and loose paint,e.t.c.. If you want a better results,use D/A sander to remove surface rust, because wirebrush will remove loose stuff and glaze up the surface,trapping the rest of rust. But for best results,blasting is the only way to get rid of it all. Picklex,Ospho type stuff does it's job just fine, but follow instructions if you want lasting results.
