Rust on stainless steel refrigerator

Are there any new updates on this problem. My refrigerator is two years old and I noticed this on the front of one of the doors. I too called Whirlpool and was told to buy stainless steel brightener which they said I could find in any Lowes, Home Depot, etc.  I haven't been able to find it and plan to purchase it online.  Has anyone used this or found any other solution to this problem. I asked Lowes about this and they said they have never heard of this happening and that stainless steel should not rust!
