Aimless,I wish I had known! I still owe you a couple of favors...
I would've done it for you.
My recipe is easy.
Old rain gutter with 2 ends about 3.5 feet long.
One 5 gallon bucket and lid.
One pair of Playtex dish washing gloves.
One package of harbor freight 3 pack of disposable steel/brass/nylon brushes.
Rags or shop towels.
1 package of fine steel wool
2 gallons camp stove fuel (the kind for the old Coleman stoves)
Field strip the gun, and remove the steel buttplate screws , door and buttplate itself and set aside parts.
Take the rifle and throw the stock and barreled action in the gutter and cover with Coleman fuel for about an hour and a half.
Use the brass and nylon bristle brushes to scrub the action and the nooks and crannies of the stock.
Take the steel wool and use it to scrub the larger portion of the surface of the steel, and remove to barreled action from the cleaner. set aside and let dry.
While the action dries work on the stock with the steel wool to remove the cosmoline that sweated out of the stock, you may have to soak the stock a number of times to get it all out of the wood,
I average about 2-3 times to get get all of it extracted from the pores of the wood depending on what model and how long it sat in cosmo.
I then put the gas tube, piston, fire control and buttplate in the 5 gallon bucket with the coleman fuel I emptied from the process into the 5 gallon bucket, and let the parts soak overnight.
The next day I remove the parts and clean the same way. the wood on the gas tube might need a couple of soakings like the stock did.
Re-assemble and enjoy!
Call me if you have questions.
