That and a hot car on a summer day....If you don't want a pan full of dripping cosmoline, another way I heard was head and wrapping it up in newspaper that will soak up the cosmoline. Everything I have ever heard about it is that heat is the best method.
Let us know what you ended up doing.
Mineral spirits will melt it like butter. I have used it for years.
Yeah, I do love my Mosins. Have gotten lots of practice removing cosmo. The worst cosmo must have been from my Albanian SKS. I could hardly see a rifle from the cosmo and that stuff was thick. I happen to like the smell and find it relaxing to clean these old rifles.Aren't you the guy that owns like 700 Mosins, Denny?
