Bests & Worsts Reviews from Amazon

I purchased this product less than a year ago. It began to appear as though it’s rusting. It comes with an insert that claims that it will not rust. I have tried cleaning it with the recommended vinegar solution. I have also tried using a magic eraser. Included is a picture of the product currently, after all efforts to clean it. Tried reaching out to the company’s support staff about my issue and received no reply. Would greatly appreciate some sort of reply from Dash. Product worked great before it rusted. Now my eggs come out with brown spots on them.
