I use a selection of brass-wire brushes in a slow drill with a light oil (WD40 will do). Steel wire brushes are too aggressive, the oil acts as both a lubricant and to pick-up the dirt.
Then clean the surfaces with a decent detergent. It's oily deposits that mark the casing the worst, get them clean and then protected with a decent polish and they'll stay good for a long time.
