Something that will emulsify the moisture and lubricate...I use Ballistol. It will grab tiny droplets (not disperse water) and lubricate at the same time. All other oil-based lubricants disperse water that can create rust it cannot reach. A friend placed 6, 20-penny nails in a mason jar filled and capped with water. He also placed 6, 20-penny nails in a mason jar filled and capped with a mixture of 10% Ballistol and 90% water. Two weeks later he checked the results...
The 100% water had rusty nails, whereas the 10% Ballistol jar were as pristine as the day he capped them.
Ballistol cleans and lubricates and creeps into crevices.
