Ive found a lot of pitting on my adventure wheels, they have just gone through their first real winter and have been washed off, with the rest of the bike, with cold water on at least a weekly basis. Its been to Astles who have photographed them for the Goimans at BMW. I was told that the BMW approved cleaner for this is Solvo Autosol!! Tried it it kinda works but talk about tedious, I still have a minor semblance of a life!! Awaiting warranty but not holding my breath ive tried AF whatever, messy and dirty and doesnt seem to be much better. Any other ideas?
