How do you decontaminate and remove tentacles from jellyfish stings?

ANSWER

For jellyfish stings, the American Heart Association recommends the following:

Rinse the area with vinegar for at least 30 seconds. If vinegar is not available,use a baking soda solution. This will help deactivate the stinging cells of certain species of jellyfish.

Next, soak the area in hot water for at least 20 minutes if possible. Use cold packs instead if the area can’t be soaked in hot water.

These treatments are based on research done in the Indo-Pacific areas, however, and may not be effective in the oceans of the North Atlantic. Vinegar may actually make the symptoms worse, depending on the type of jellyfish. Some experts recommend removing the stinging cells and rinsing in seawater.
