I use an electronic contact cleaner spray which I apply with a Q-tip. Hosa D5S-6 DeoxIT, by Caig Laboratories.
Dirty hotshoe contacts (and battery contacts too; don't forget those) are the source of practically all my flash misfires. It similarly affects the radio trigger devices. I'd be leery of using isopropanol though. Better than nothing, but I have found it may leave a non-conductive residue.
