Sure - PB Blaster's Penetrant product works wonders, but use sparingly and BE PATIENT. (You can help its action along using a hair dryer). Keep it off the wood on the gun and wipe away any excess from the vent rib posts after applying.
For super crudded up/truly frozen tubes, use a 75/25 mixture of new (fresh) ATF fluid with acetone warmed to a temperature that won't exceed that of the rib solder (I've forgotten what that is) and slowly bleed it into the thread rims of the tubes in the barrel.
The super viscosity of the new, pure ATF is "supercharged" by the solvent as an accelerant in penetrating the threads the full depth of the tubes, and the resultant capillary action reaches the most microscopic points of contact between the tube and barrel threads. This can be done with the barrels upright or (better still) plugging the bores (wine corks work great depending on gauge) and pouring 2-4 oz. of the mix in from the chamber end using a small funnel and plastic hose. An hour or two of this treatment is usually sufficient, but doing it later in the day and letting the barrels hang overnight gives the penetrants the ultimate exposure time.
PRECAUTIONS: Don't get any of this magic brew on your wood or the stanchions (posts) of the vent ribs on your barrels (which is why I think hanging the barrels vs. the muzzle end bleed) is best.
Also be VERY careful heating acetone - no flames anywhere near it (the small desk coffee cup warmers work great). The only thing I know of more explosive is ether!
