I use Hoppe’s #9 (the old formula-stocked up on it years ago when there was talk of changing it due to EPA regs...) on a Bore Snake for the barrel.

I use whichever spray blaster I have on hand & a toothbrush for the frame & slide.

I’m a big believer in synthetic lubricants; I especially like Tetra-Grease and Shooter’s Choice.
