Product review (3 stars): Real stainless steels don't corrode in the way the wire rack on this product does
Good looking rack but I am highly skeptical that the wire rack can properly be classified as stainless steel.  The wire looks like chrome plated steel to me, and as several other reviewers have noted it does develop red rust that gets worse over time.  At first it's very light and can be scrubbed away, but it gets progressively worse.  The side panels might be stainless - They're a believable color for stainless and mine haven't shown any sign of corrosion, but that is hardly justification for selling this product as stainless.

No steel alloy, stainless or otherwise, is completely invulnerable to corrosion.  I do like this rack better than the plastic-coated ones that are so pervasive, but it's unfortunate that KitchenAid has put its good name on something sold deceptively.
