for solvent, use that gel paint stripper stuff you get from the hardware
store. paint it on, leave, then wipe. repeat until cleaned. it takes
a while. you'll find it does a great job of cleaning carbon from the
combustion chambers too.

the white deposit stuff, i don't think that's much of a problem. if you
want to use a wire brush, that'll be fine - just don't brush the sealing
surface of the head.
