I just experienced the same problem, I tried WD40 and it is working! I used a blade to scrape the white film and I wiped most of it off (blade is an option) It is hard work.
I and several of my family members have these telfon pads. We all placed them on the 'floor' of the oven and have never had a problem. My mothers stove is the newest and she doesn't have that problem. I am wondering if maybe you turned the 'clean' on and it made those spots, while the pad was on the oven floor? Sorry I don't know what to tell you to do to take them off.
I have just never had that problem.
You can try Mr. Clean Magic erase.It pretty much takes any type of stain out. It is amazing.
