The grease is probably cosmolene. I bought an AK parts kit years ago that was caked on it. I used solvent (gun cleaner) and elbow grease, mine wasn't dried out though.

Set your oven to 125-150, heat the cosmo
and it will drip off. Place a pie tin or foil under it to catch the cosmo. Thank me later. |

If its cosmoline - try putting the BCG in a pot of hot water and let it soak and soften. Stiff bristle brush (nylon) after its been in there a while, disassemble and clean with degreeaser all the nooks and crannies out and then relube.

The ultimate method for removing dried on cosmolene etc, is EasyOff oven cleaner. Take the part outside, spray with hose, spray liberally with oven cleaner, let sit for 30 minutes, hose off again and wipe off with rags. In extreme cases, a second treatment may be necessary, but usually not.
Works great on dirty milsurp stocks too, but you need to take care to wipe down the wood with a rag soaked in vinegar, after it comes clean. The acidic vinegar neutralizes any residual lye remaining from the oven cleaner and eliminate damage to the wood. - CW |

Cosomoline is basically grease mixed with wax. As others have said, heat is the best for melting the wax for removal and degreaser/soap for removing the grease.
there are people that still use it, a friend just got a Bushmaster that had it as well. |

Hot, soapy water and a plastic brush....flush with WD 40 or rubbing alcohol to chase the water when you're done. Lube as appropriate.

Is have always just used a heat gun or hair dryer to melt it then use a solvent and tooth brush to clean it up.

Try a heat gun on it first. If the stuff softens up with the heat gun, it's almost certainly cosmoline, and will do well in a warm oven. If it doesn't soften, it's something else and needs harsher methods.
I would not use oven cleaner on a BCG, because I'm not certain that the corrosive chemicals in the cleaner would leave the phosphate coating alone. Heating it up and using mineral spirits should work for any sort of preservative. |
