Warning about teflon oven liners
I ordered a Teflon oven liner for our new house because I had one in my last house and it worked well. I thought I got a bargain, but when I received it I noticed that this one was not of the same thickness and weight, but I used it anyway. Well, it ended up melting and adhering to the oven bottom, leaving a permanent dull residue that we could not remove (see picture). We ended up ordering a new oven bottom which, fortunately, was less than $40 with shipping. I hardly ever use my oven (I'm not a cook) and have never used the self cleaning option, so the oven never came close to the 500 degree limit. So, here was another example of "you get what you pay for" and I learned my lesson. Just wanted to share so you don't make the same mistake.
