Cleaning up my Mosin Nagant 91/30 | Page 2 | Homestead Security | Forums

A while back I bought a bunch of uzi mags covered in cosmoline. I have a kerosene fired pressure washer in the shop for keeping my trucks looking spiffy. I disassembled the mags, turned up the heat to 200 and blasted them with soapy water. Dried them off, applied a coating of gun oil and I was done. It was by far the easiest and fastest way I have ever removed cosmoline. The self serve car wash places don’t usually have the psi of the commercial pressure washers, but I think it would still get it done. As a side note I probably wouldn’t try to pressure wash the stock.
