Compressor question.
I know about the airbrushing and painting section, I just think my question may reach more folks here.
When I'm done with the compressor I always drain it, never see or feel any moisture leaving the drain valve. My question is, is it best to leave the valve open until next use, or close it?
I'm guessing the open position could help with drying/evaporating any residual moisture film left on the tank walls, if any actually does remain. The compressor is a California Air Tools, twin cylinders with 6 gal. aluminum tank.
If someone with specific info could offer an opinion, it would be appreciated. Thanks in advance.
