Pure, lab grade ethanol or Lighter Fluid (Ronsonol). I prefer the alcohol - if
you can't get ethanol, then isopropyl alcohol is easier to find.
Both vaporise totally though, if they find their way inside, they'll
delubricate the lens!
I use a lightly wetted cotton bud (Q-tip). You can get the type made for
make-up application - they have a paddle shape on one end and a pointed tip on
the other.
I wouldn't soak a toothbrush and scrub - too much fluid flying around.
