Cleaning the boxer motor?

[Leo]

Has anyone come up with a solution to clean the cylinderheads of the boxer motor?
I have spend zillions ZAR on brushes, etc and the cylinderheads on my 1200 has a (permanent) semi brown colouring.
Anyone got any suggestions on how to CLEAN it really nice & shiny like the day I got it / or pretty close to that?
I have used that little rough part that I pulled of a spunge, and it works quite nice in those grooves but that's friggen hard work - I'm looking for a quicker easier sollution.

Heard of a place that does sand blasting but with little plastic pellets, almost like BB gun bullets, but has never seen the end result, nor been able to find the place.

Anyone got any advice?

Back in my stupid days I rode a Triumph Tiger , and would spray Mr Min on the engine, then start the motor and let the heat dry the Mr Min and violla ........Engine looked like brand new, but that doesn't work on the boxer!

Please any advice from topless washers to what-ever - I'm listening
