Quick note of caution:
I was cleaning a handful of titan manuals recently. I put 190proof (95%) ethanol ("Everclear") into a shot glass; just enough to cover the
threads on a battery and set them in there for a minute or two... then using a brush to clean one, letting the others soak for as long as that took, and so on until all were done. ONE of the batts almost immediately began to delaminate the velvet/satin coating to reveal a standard glossy finish. That was a blue camo stealth. The others did just fine with even longer exposures to ethanol. They were: olive, cigar, and red camo. I don't think its a matter of production batches, or underlying color that made that blue camo suffer. Its probably just a minor flaw in the finish at the
thread-joint that allowed ethanol to get under it.... which any of the others COULD have had, but didnt. So, test each one individually and limit exposure on all of them.
Of course the vapor KING (standard diamond, non velvet) batts showed no signs of damage.
