Wolber M59 anodised chrome magnesium rim cleaning

Hi, I have recently got a ~1973 Chas Roberts bike to restore. The wheels have Wolber anodised chrome magnesium rims (according to the decal on them). These have a white patchy surface on parts of them. Does anyone know the best way to get rid of this without damaging the rim?

The reason to anodize chrome magnesium is usually to provide a surface for the paint to adhere to, so maybe, maybe the marks are on the paint in which case polish will remove them or for a more abrasive approach, T cut.

Post a close up pic of the affected area.

For the life of me I cannot remember how to post a pic! :oops:
There's no paint on the rims - do you mean a chrome polish would do it?

Sorry I assumed they were black rims, if they are anodized aluminium or magnesium Autosol will clean them, if the protective anodize is worn through in places then the metal underneath will oxidize and produce white patches, either way Autosol will bring them back to a shine.

Don't use anything abrasive as this will scratch or wear away the anodized layer.

Great, thanks!
