Hi All,
yessssss its that time of year were the winter tyres are coming off and the summer tyres back on

. Back to full speed down the Autobahn.
My question is both set of tyres have alloy rims, how do I clean them without scratching them to bits? I must admit to my shame

, when the summer tyres came off last year I did not clean them

, just chucked them into our garage.
Now wanting to do it properly I need some advise. I have tried some special alloy cleaning stuff which didn't work very well (no wonder with the grease and dirt on it).
Thanks a million...
