OHHH NOOO!!! , you can try to fix or at least lessen the blemish but you need to take y ou time doing so. being depending on the door freezer($650) and refrig($525) replacingthe door not a viable solution.. just like a piece of wood your refrig door has a "grain" to it, i would get some WD40, and VERY lightly at first and incresing the pressure as you go rub over teh spot with the grain of the metal(generally runs up and down on the KA refrig doors. the WD40 will act as a cutting oil and clean ,polish, and protect the metal as well the dull spot was probably caused be circular motion of previous cleaning, straight lines only up and down following the grain you should def reduce the blemish

I would try a product called Evapo-Rust! Evapo-Rust will remove the rust without damaging the stainless steel finish on your refrigerator. After you remove the rust you will then want to apply a rust inhibitor to keep it from coming back. You can go to a website call http://www.rustremover.biz to learn more about Evapo-Rust. You will also find that they sell a water based rust inhibitor that will work to keep the rust from flashing back for up to 6-months.
Stainless steel is a term for a family of high chromium steels, some of which do in fact stain, although they do not rust as ordinary steel does.
The more expensive 'austenitic' stainless is non-magnetic, but harder to work into product shapes. 'Martensitic' stainless is a little more prone to staining and corrosion, but easier to work with, and is magnetic. Then 'ferritic' stainless is even cheaper, but less corrosion proof, and is also magnetic.
So yes, many stainless steels are magnetic, and if the manufacturer has not used the very most corrosion proof but expensive grade, then you will see it in that way. I would not see much reason for a fridge door to be made from austenitic stainless.
