Chico’s thought on cosmoline is the ultimate long term preservative…

Traditional cosmo application involved heating the cosmoline / grease till it becomes a liquid and submerging the parts completely. Another lifetime ago I was a gunsmith, or small arms repairman and spent a lot of time removing cosmoline from parts and complete units by washing them in a tank of dry cleaning solvent. After a while, the cosmoline was in solution with the solvent, so I began dipping other parts that I had repaired and cleaned back into the tank for a very light reapplication of cosmoline. (I batch dipped 200 new 9mm pistols for a deployment to Panama, not a single rust issue returned…)

In this lifetime, I do something similar only with Vaseline Petroleum Jelly and low odor mineral spirits. The Vaseline doesn’t leave the putrid smell like cosmo, and in a thinned out application, it flows into the metal pores and other areas, when the mineral spirits evaporate, you have a thin coat that protects, doesn’t smell bad, doesn’t stain your hands or your clothes, and doesn’t interfere with immediate use of your tools. ( I mainly use this mix on my impact sockets, metal files, chisels etc.) A quick dip in the table top solvent tank, and a drip dry before going back in tool box.

I started with two gallons of mineral spirits three years ago, but evaporation and use has me down to about a quart of solution today. With the price of mineral spirits now approaching the same price of a gallon of WD-40, I think I’ll switch out my solvent tank straight to WD.
