Many of the dive boats in the Florida Keys have white vinegar readily available on the boats. This works almost instantly on moon jelly stings as well as fire coral and stinging hydroids.
Portuguese Man O wars are a totally different ball game. Vinegar will help a little but not as well as (believe it or not) Adolph's meat tenderizer, or other, preferably liquid, meat tenderizers.
The first time I got hit by a MOW I just sprinkled it on the stings. Didn't work at all. Next time I got hit with one I mixed the meat tenderizer with salt water (NOT FRESH), then applied it. Did the trick. I've heard lots of people say it doesn't work. My guess is, they just applied it dry, or with fresh water.
Safe Sea works great for sea lice, and some jellies. On the bottle it warns that it has not been tested against MOWs or box jellies.
Florida (and probably the rest of the Caribbean) get MOWs usually in January and Feb.
