Question about non-stick Teflon pots/pans
I think the non-stick stuff is called Teflon, right?
Anyway, I was wondering about how long you can use a non-stick pot before it needs to be disposed of and replaced?
I have 2 large non stick pots and one of them which is less frequently used is still dark black and smooth inside. The other which we use more often is light grey and more rough texture inside.
And I noticed the other night when I went to fill it with water that the water always bubbles up as if there is soap in it, but there isn't. The bubbles go away after a few seconds but its not like normal water bubbles, they act like soap bubbles. And the other pot doesn't do that.
Is it safe to keep using a nonstick pot that has turned light grey and you can see the silver underneath? Thanks!
