Cleaning Bosch pump

[blinkyeatu]

I've dissembled my pump and wondering what the best way to clean the bits that are exposed to the outside world; main block and top. I've gone at it with brake cleaner and a wire brush whilst it almost does it, it still leaves a load of crap. I was thinking could I soak them in hot water maybe abit of soap, rinse, stick them in the oven on a low heat evaporate it all off then Dw-40 and brake cleaner for extra measure I want it shining
