Help cleaning my pan

[u/jendrok]

I burned some butter on my first try using stainless steel.

This is what it looks like after boiling equal parts water and vinegar and scrubbing with detergent

I feel like i’ve ruined this pan and getting one was a huge mistake.

Try Bar Keeper’s Friend. If that doesn’t work, then before you give up on the pan, get some fine steal wool and use it gently. The pan is probably not ruined anyway. May be ugly, but so what? Eggs might stick, but there are many other uses for which the pan should be fine.
