    Both. I used to clean cosmoline off of VW's . They came coated with it for shipping overseas. I used a steam sprayer with kerosene injected into the sprayer. Worked great for big job's like cars.

    WD40, rag, toothbrush. Then lube it with something better after you clean all that gunk off.

    I have used mineral water to strip cosmo, but the best way I found is to remove grips if rubber and get a clothes steamer and a five gallon bucket and some distilled water. I have used this method on metal and wood stocks as well. You hit it with that hot steam and the cosmo bubbles up and drips into the bucket or you can just wipe it off. Then just a good cleaning and oiling.

    Gun Scrubber.

    Take the grips off of the gun and field strip it.

    Put on a pair of latex rubber gloves.

    Take the gun outside, choose a place where you don't want grass and flowers to grow and liberally hose the gun parts with Gun Scrubber letting the gunk run onto the ground. It has been a while since I have handled my P64 so I don't recall off hand how hard it is to remove the firing pin. However I would remove it and blast out the firing pin channel.

    I figure on using 1/2 can of Gun Scrubber per gun.

    Boiling water.
    Everything else is not any better and costs more.

    I have a gallon tin of MS (handle marked COSMOLENE) in the garage for just such a purpose.

    Whether actual cosmo on a milsurp or shipping oil on, say, a new stripped AR15 receiver half, I first treat them to a nice, relaxing soak/dip/scrub in the MS from that tin.

    My next step is detail-strip (if applicable) for close inspection and cleaning.

    S'just my method ... :)

    I went the mineral spirits way, had an aluminum tray, field stripped my Bulgarian Makarov dropped it in the tray (completely submerged) and left it for 2+hrs. The cosmoline came off easily and I had such a positive experience with this method that I'll definitely use it in future.

    Gasoline works very well but could be dangerous. Mineral Spirits works too.

    Sounds like my best bet is to remove the scales and disassemble the action and soak in mineral spirits.

    I cleaned up about 30 M1 carbines mags that had been stored for 50 years. The cosmoline was thick and there was lots of it. I bought a gallon of mineral spirits and soaked them over night. Blew everything out with compressed air the next day. Clean as a whistle.
