The best way to clean it is to remove the sideplate so you can get a brass brush in there to scrub it. Just be sure to not mix up the sideplate screws as the lower forward screw MUST go back into its hole. Also, don't pry the sideplate to remove it. Rap the bare grip frame with the wooden or plastic handle of a tool like a hammer and it'll vibrate free. The sideplate is swaged to the frame and fits very tightly.

Pardon my rudeness. Welcome to the forums from the Wiregrass, mlward!

If you don't feel comfortable doing that, then a soak in auto trans fluid for about a week followed by a flush through the hammer and/or trigger openings with aerosol carb/parts/brake cleaner until the effluent runs clear may do it. Just take the grips off before you soak the gun. For extra crud removal, mix the ATF half and half with acetone and put everything is a sealable, chemical resistant container. After flushing, lightly lube the action with a good gun oil...about 5 drops is plenty and a drop on the yoke arm and ejector rod. She'll probably last another hundred years.
