Great idea!!! I dug out some of my nylon bristle gun cleaning stuff and shined up those thread nice!!! I wonder if Hoppe's would work good? Works on my 9mm and doesn't damage anything, but leaves that nasty gun oil odor.
Hoppe's should work fine. If it can be used on your gun, it can be used on your GG. I use gun oil to lubricate the threads on my GGTS and Ox-Gard on the connections. Besides, I like the smell of gun oil
