Ok I gave the old girl a good old clean on Sunday (my god my back is now killing me, bent over for too long) and I could not get the oil/muck off of the back wheel, I used wheel cleaner, soap and water, I didnt try any white spirits or anything as they are Painted wheels and some of the paint has come off so I didnt want to use anything else that might harm the wheel.
But I still could not get the muck off, does anybody have any wise ideas on how I can shift the grim please, as the rest of the bik now looks sweeeeeet but the wheels look a little rough.
