I read about dry ice blasting in a UK magazine a while back, the suspect it
will become more and more popular due to environmental laws. Apparently the

gentle abrasion not aggressive and is apparently safe on all sorts of
delicate components. Its meant to be really good and there is not messy
detail cleaning up after.
