Summarize this article:

Gently take off any clothes or jewelry near the burned skin. Try not to pull clothes over the burned area to keep from irritating your skin further. Turn the faucet on so the stream of water is gentle rather than strong. Rinse the burned area under the cool running water to remove any traces of vinegar and soothe your inflamed skin. Do not rub or scrub your burn as you rinse. Avoid using soap on your burn. Remove your glasses or contact lenses if you've gotten vinegar in your eyes. Blink your eyes under a gentle stream of room-temperature water for 20 minutes. If your child has gotten vinegar in their eyes, gently pour the water over the bridge of their nose and encourage blinking. Then, flush their eyes with room-temperature water for 20 minutes in a tub, shower or sink. Use only clean, fresh water to cleanse burns. Other liquids may further irritate burned skin rather than soothing it.

Summary:
Remove clothing or jewelry that has vinegar on it. Run the burn under cool running water for 20 minutes. Rinse your eyes for 20 minutes with room-temperature water. Avoid using milk or other liquids to flush a burn.
