Does vinegar neutralize jellyfish stings?

Your best bet in a pinch is to douse your skin—and the tentacles on it—in vinegar. Find the most highly-concentrated stuff that you can and pour it on. Vinegar inactivates the jelly’s nematocysts so they can’t fire, which means when you go to remove the tentacles you won’t end up with more venom than before.

Jellyfish stings cause immediate, intense pain and burning that can last for several hours. Raised, red welts develop along the site of the sting, which may look like you have been hit with a whip. The welts may last for 1 to 2 weeks, and itchy skin rashes may appear 1 to 4 weeks after the sting.
