Hello all, I've used the search function here and on Google to answer my question, but haven't really found what I'm looking for, so I'll ask. Also, apologies if this thread belongs in another forum section. I've got an older, used Remington 552 Speedmaster .22 that I picked up awhile back at a gun show (overall in good, decent shape - good bluing, good bore [I think], good wood, not banged around or scratched up). I finally got around to breaking it down, and it's gummed up and crudded up inside something good - the deposits are like solidified, hardened clay pieces (it was actually really, quite tough to even separate the barrel/bolt assembly from the receiver - only worked after I let some Break Free soak in there for awhile). I've got the bolt and ejector soaking in bore solvent, and I'd like to do the same with the barrel, bolt assembly and receiver. Is there any cheap solvent I can get bulk that I can use to soak these larger pieces in? Mineral spirits? I've got them sitting, saturated with bore solvent at present, but I'm thinking soaking would work better. Overkill? A co-worker of mine who was in the 11th ACR in Vietnam ('70 - '71) told me that they'd just dunk weapons into barrels of gasoline. Good idea? Not good idea? Thanks, all. I appreciate your time and assistance, -Jess P.S. Do I need to worry about breaking down the bolt itself and get cleaning in there? or, am I getting in over my head and setting myself up for bringing in a handful of bolt parts to a gunsmith?
