Why not use both? I'll remember the brush next time I have to change GPs.
I guess if you're really curious, try the brush first and then the reamer on the first port. Then do the opposite on the next port. Not a controlled study but it might satisfy your curiosity as to which, if either, does a better job.
If a brush was better, wouldn't MB have designed one for use in their cars?
