Default Will Deoxit on a circuit board cause problems?

Think about it for a moment. If a switch lube were conductive, and
you sprayed it on the switch contacts, one might expect the switch
lube to short out the switch. That would make it a very bad switch
lube. Therefore, one might suspect that NOT shorting out the switch
which Deoxit is trying to lubricate might be a formulation
requirement. In other words, it better not be conductive.

Deoxit is mosly mineral oil (saturated parrafin oil) which will
evaporate, but very slowly. You'll need some kind organic solvent to
clean off the oil residue from the PCB. If you using Cramolin Red
instead of Deoxit, there's some oleic acid in the mix as an oxide
remover, which will very slowly corrode copper and must be removed
from the PCB.
