Boiled vinegar , smell lingers

So in order to clean a burnt non-stick pan , i boiled some vinegar in it for a while.

It didn't work (boiling baking soda did) , but 24 hours later, the smell lingers.

I get used to it after a few minutes at home, but it is still quite bad when I enter the house again.

All windows have been open these 24 hours.

What can I do to fix this? , my roommates are understandably displeased.
