I uses CRC "Dry" silicone to clean magazines, which I disassemble first.
I spray them liberally, wipe them dry, and reassemble. The heptane (white gas) propellant evaporates and leaves a trace of silicone on the internal parts. Don't forget to clean and wipe the spring, also.
The .22 ammo often has a wax coating that builds up in the magazines, even when you can't really see much of anything.
