Does one need to apply oil or ballistol INSIDE the lock?

[CS]

Hi all,
I came to realize (been a year roughly since I started getting into this hobby!) that I need to take better care of my flintlocks. Was wondering - do folks typically worry about rust INSIDE the lock, and if so, do they do the same thing as exterior i.e. apply ballistol or oil?

And does one have to dissassemble the lock and apply to every piece (tumbler, springs, screws, sears, bridles, everything) , or just broadly apply the ballistol on the entire lock inside and out?

Thanks in advance, guys (and happy thanksgiving)!

I usually clean my locks in a pot of hot water with ballistol. After cleaning I'll dry it off in the oven set on low which leaves a fine film of ballistol coating all of the parts,

Disassembly not required, At home I usually remove the lock from the gun and scrub it with water and a toothbrush, dry with compressed air and use some light oil on it (Nothing that will gum up or lock things up in frozen weather.
I love Ballistol but it is a little to heavy for this in my opinion.
If staying somewhere overnight and hunting/shooting again the next day I do not remove it and save the cleaning for later.

You don't need Ballistol. You don't need to disassemble it, either. I clean with hot soapy water, rinse with hot water, shake off the excess, then dry. I have a small bottle of oil with a needle tip, I oil the tumbler, sear, and frizzen pivots, just a tiny bit will do, and work the mechanism to spread it over the bearing surfaces. You definitely don't want too much as it can attract and hold dirt.

If the lock fits snug against the barrel, it shouldn't need much of a cleaning.
