I have a yugo m48 and have decided to start shooting it. Never seen so much cosmo and have no idea how to get it off tthe stock?
 
I've heard that hanging it from a tree in July anywhere south of Saint Louis with a bucket under it will get most of the cosmoline out of the wood. Arkansas should get warm enough for that to work.
 
Heat is the best way, as it doesn't take all that much to simply melt the stuff. The most common method I have heard of is taking the stock, putting it in a black trash bag, and leaving it in the sun. Take the stock out every couple of hours and wipe the cosmoline off, then put it back. It takes a while, but it's pretty good at sweating the cosmoline out of the wood.
 
I use two sides of an large cardboard box covered with tin foil (shiny side out) to create a "reflector oven". Prop up the stock, and let the sun do the work, stopping by every couple of hours to wipe it down. Nice sunny summer day and some patience works ever time. In the winter, or in a rush, use a heat gun on a low setting.
 
If you have a galvanized container you can boil water and put the stock into the container outdoors. Just pour the water over the stock and let it collect in the bottom. I boil them out with a bluing tank when I need to do it. You can get one from Midway USA for about $40 if you want to go that route.
 
With my Mosin I tried the naptha/solvent idea but there was still lots of cosmo in the wood. The solvent simply got the surface part and the rest was still deep in the grain.

Last summer I simply put it out in the sun and wiped it down every hour or so. Did this for a few days until it didn't sweat cosmo any longer.

The dark coloured garbage bag sounds like a nice idea as well. Or I may use an old length of 5 inch heating duct painted flat black in the future. Simply seal the ends with something to prevent air flow and let the sun turn the duct into an oven.
 
I HATE COSMO

Took me an hour to break the thing apart . I actually had to use a rubber mallet to pound the rings off. Cosmo had them sealed to the wood but worry not the wood is GTG with not scratches or dings. Soaking the medal in a bore cleaner gonna try the sun and black trashbag this week.
 
Sweat Box is the answer

I built a sweat box for my milsurps. It;s tinfoil lined with two light bulbs for heat. The top lifts off to hang your stock or barrelled action from and the bottom has an opening for a drip pan to catch the cosmoline.

Works great and is not hazardous to the stock or metal.

Heat. Here in Gerogia I wrap my C and R guns in black trash bags and let them sit in the cab of my truck on a hot sunny day. The cosmo runs right out.
 
well the sun didnt work but it aint that hot yet so I heated up a pot of water and used steam and a corse wash pad for dishes. Got most of it off but now the thing looks like garbage. Looks like i stripped the finsh of . I guess that would make sense as there was no real finish to begin with? Plannin on some very light sanding to smooth the wood out a bit and maybe rubbin some oil on it.

any ideas or advice would be appreciated!
 
a lot of guys put the stock in trash bags and put it in the car on a hot day to draw the cosmoline out of them. I boiled all the metal parts and just wiped all the surface cosmoline off the stocks on mine, I figure it's easier than taking the time to get rid of the cosmoline and then take the time to apply 5 or 6 coats of linseed oil to them. one thing you may try is laying out tin foil and setting down bricks to elevate it a couple inches off to make sure it doesn't get too hot. that may get hotter than the car cab.
 
Build a hot box...

Large metal trash can with lid. (will be laid on its side.) (<--->)

2 or three porcelin light sockets with 2 or 3 100 watt light bulbs (not the new energy bulbs) wired inside the can in a line ( *|*| *) on the top of the oven -> inside can

A couple of oven racks, or heavy screen shelves (for inside of can)

Wire the lights in sync, run the power cable outside of the can) I use a power cord

Optional install in the power line a light dimmer switch.

Optional digital temp device to monitor heat inside can.

Place rifle on the rack close the lid turn on the lights,. The heat from the bulbs will allow the cosmoline to "Drip away" from the rifle. control the heat by bulbs or dimmer switch.

This is very effective, the can can also be used to bake on color coats etc.
 
Non bleach Tilex. I was busy cooking my M1 Garand stock for DAYS and while getting the stuff out, it was slow. Tilex rips off the top layer within minutes, and as long as you use the non bleach version, no wood damage. Putting the last coats of tung oil on the stock now, looks gorgeous. Before I began the oil, I let the gun sit for nearly a month and say no cosmoline raise to the surface, so I think Tilex was a success.
