Hi Frank,How did you get the grime off the wire wheels following your trip?
My Son bought me the Morgan Wire Wheel Cleaning Kit for Christmas
It's a 'Wheels Off' job and a bit messy but mine were caked 5mm thick with dry crusty muck between the spokes so the solvent part disolved that stuff nicley.
I was not so impressed by the 'Rinse' product as it did not give the wheels the usual sparkle. That's may be because I was starting from a very low base.
I have since used my car polish to clean the rims again to help remove the fine scratches caused by the many abrasive Mud Washes they got along the way.
