Don't know about a Tok, but a 5-gallon bucket and a can of brake cleaner spray has worked for me with Yugo SKSs in the past.

Low heat also works well. I use my wifes blow dryer set on the highest setting for wood. Boiling water also works well for metal parts, just make sure you dry thoroughly and re-oil..

Mineral spirits is the quickest/easiest method for the metal parts.

be careful with the brake cleaner it will knock you out
speaking of that starting fluid can also be used
it will knock you out if it gives you more than a buzz it is ether

Mineral spirits for the bulk of the work, brake cleaner for the fine parts.

Also, letting it sit out in the hot sun (while we still have it) helps.

Gun Scrubber eats it off with ease. Just need a few qtips and a tooth brush to clean the cracks. At least that how I did my last one.

If you use brake cleaner, you MUST replace the microscopic layer of protective oil or it will quickly rust. A better alternative is kerosine (diesel will work but I like kerosine better). It will remove the cosmoline plus it will leave all the microscopic pores filled with a layer of protection.

This. I filled a Maxwell house container with a 50/50 solution of water and SG and tossed in my cosmoline coated PSL bolt and magazines and let the sit for 2 days.

Running hot water afterwards to knock the loosened junk off then a hair dryer to ensure no water was left. Finally a legit use for that $150 Chi hair dryer my wife thinks she snick in under the radar.

You kids never ran into REAL Cosmoline. It was wax melted into hot grease. The firearms were dunked in it and left to dry. After a year or so the thinner oils evaporated leaving a sticky, waxy mess that gathered an armor coating of dirt. Damned near impenetrable, solvents only softened it a little and you had to wipe forever. Back in the 70's there was still a lot of stuff in storage since WWII that had real Cosmoline.

Most "Cosmoline" today is nothing but a thick grease, although it may have some waxy hydrocarbons in it, and any degreasing fluid and wiping will get rid of it.

Completely unnecessary. 30 minutes in mineral spirits is more than enough.

Thanks for letting me know that you are a zen master of degreasing/cleaning though and that my cleaning method is unnecessary.

Simple Green doesn't make me want to hurl due to the vapor, and I have GALLONS of it on hand [smilie=021.gif] less than 5 minutes of work and my parts are perfectly clean. I think I'll stick to my method, but to each his own.

I think his comment was the time you quoted :ham'r , the first time you said, let it sit for 2 days, then he commented about unnecessary and 30 min, then you said something about 5 minuets :-k

all I have to say to both you zen master baters =:wvr ... is soak an AR, SIG or GSG in Simple Green for a while and let us know how that works out for you, I personally wouldn't use simple green on anything metal cause it corrodes aluminum [-(




p.s. its funny you think other solvents have a vapor ...SG smells like a dead cat in peppermint schnaps to me [smilie=011.gif]
