Chemical purge compound
Vol. 25 #1, May 1998

Chemical purge compounds can be very effective in cleaning degradation from a screw/barrel, to reduce the need for pulling the screw. Also makes pulling the screw and cleaning it much easier.

A number of them are on the market with good vendor support.
