Removing Cosmoline with Hot Water

We have a bit of a departure from normal content today – I needed to clean up a really greasy C96 Mauser, and figured it might be useful for some folks to see the process. Cosmoline is great stuff for protecting guns from rusting in storage, but it can be a rear bear to remove. This particular C96 seems have been dunked in the stuff, so I decided to try boiling it in water to melt the cosmoline rather than clean it all with rags and Q-tips. I should note, though, that you don’t want to do this with wooden parts – I left the grips off to clean separately.
