Got to agree power to the elbow seems to work, or oily rag run over the shiny bits in the winter outings.You have still got to get those elbows working.
I use RFT a soft brush then the hose then onto the ramp so I dont put my back out in with autosol stuff on a nice office chair and work away... Works for me.
I had my OZs rebuilt at Renowheels, Tony said he would only use ( Silvo polish wadding also known as Duraglit )the wadding is very soft so won't harm your rim's but will give you a mirror finish to your wheels, its great for alloy centers as well.
Cheers for the feedback, elbow grease i kind of thought was the way, more fishing for any special products, think i will go the Duraglit route as my where dome at Renowheels also.
