Cosmoline Adventure

Everyone likes getting mail, so when the package arrived, I couldn’t wait to get it open. I suspected it was the sailor’s knife I recently won on eBay. I opened the package and found a cocoon of newspaper. When I sell stuff on eBay I try to pack the item so no damage can occur. After all, once it sells, I am sending it to its rightful owner so I want to be careful. So, seeing the wad of paper, my first thought was “wrapped the way I wrap things!”


Unrolling the knife revealed a grease covered slathered oval shaped object.  Well, there was so much cosmoline I wasn’t sure there was a knife present.


The time honored method of cleaning cosmoline from rifles is to stand in a hot shower in your skivvies and scrub the rifle with your toothbrush. Yuck…


I knew I needed a different way. I did find a site what showed a hot steam method and listed other methods of cleaning cosmoline.

Partially cleaned - Now for the soak!

The best I’ve seen was a large two-tub ultrasonic unit at the Knob Creek Machine Gun Shoot. You just opened the bolt and placed it in one tub for half an hour and then into a second bath which contained a rust inhibitor and light oil for a second half hour. When you came back your rifle was waiting for you. The cost was around 25 bucks and everyone who bought a surplus rifle thought it was a deal!


I wiped the majority of cosmoline off with old newspaper and submerged it in a solution of equal parts:


Mineral spirits,
Clenzoil,
WD40.


Between an old toothbrush and a spare turkey baster, I cleaned off most of the cosmoline. The blade compartments were too deep for my brush, so I cut a strip of cardboard and scoured them out. Still, it required a lot of soaking. If I were smart I would have left it in the solution overnight, but I was too impatient to wait.

Nothing Like a good soak

I finally got the gunk out of all the nooks and crannies. My cleaning solution went from a nice clear green to a muddy, turbid gray. I was afraid to use it on anything else, so I disposed of it.


It took a lot of wiping with rags followed by paper towels but I got most of the solvent removed. I suspect it will have to wait for a sunny hot summer day when I can wrap it in newspaper and leave it in the sun while I work around the yard. It would not surprise me if more cosmoline worked free in the heat.

Well at least I don’t have to worry about oiling it or protecting the blade for awhile.
