Got car back today from oil change / wheel bearing replacement and the dealer had washed it, and cleaned wheels, blacked tyres etc.
Now the car gets 2 bucket wash with lambswool mitt each week or two using posh shampoo, and Jeffs Werkstat prime and jett treatment every month or two.
Wheels are a bit neglected but washed with the rest of the car.
Noticed today now the ingrained dirt has been removed that one wheel seems to have bubbles or blisters along the edge of one of the spokes ... maybe be winter salt or something attacking... but until I attack the blister not sure! It isn't just a lump of road grime!
