Today i have a car to service in my workshop same age as mine and the chrome wires on the inside rims (the part no one sees) has got quite some rust and corrosion going on.
For my cars that have chrome wheels during the winter I give a light coat of WD40 as MWS wheels recommends and over the years has maintained the chrome to a high standard.
I was wondering how many know this and its certainly worth doing, this of course is not needed on stainless wires.
