Chrome plating with surface rut, not pitted, can be easily dealt with with aluminum foil. I never use wire wool to attack chrome issues. Too hard, too oxidable and too bad about the first two.

Use a soft wire brass brush, to knock as much of the oxidized material as you can followed by a gentle rub with crumpled up aluminum foril...


These head tube lugs were done with the brush, foil and elbow grease - and nothing else...



Sadly, rust pitted surfaces do not respond well to the aluminum foil thing. The fenders were just too damaged for decent repair, so I cleaned them off, roughed them up a wee bit and painted them to match the old Torpado...



Dish washing plastic scrub pads are helpful and I do use them for surface cleaning and even low level alloy polishing (not a shiny shine but a satin like patina when done on alloy)...


Hope that is a help.
