<human>: Can you summarize the given text in a few sentences?

I've had a Calphalon saucepan for a few years now, and because I'm a lazy bastard, I always washed the thing in the dishwasher.  What's the worst that can happen, right?  Well, I learned.  Nice powdery gray coating on the entire thing.  It's ruined for cooking - that powdery gray crap will get into everything.  Or will it?

I decided to refurbish my saucepan.  First, I made a resolution to never again wash it in the dishwasher.  Next, I took a Scotchbrite pad to the whole thing - stripped off the non-stick coating  (the hard anodized one that never really worked for me anyway) along with the gray powder that I now assume is aluminum oxide.  My third step was to season the pan with Canola oil, to try to seal the cooking surface a bit; I am now treating the pan as a regular cast aluminum pan. 

Anyway, has anyone else tried anything similar to a ruined pan?  

As a side note, I will never again purchase Calphalon cookware.  They're too much of a pain to maintain, and the warranty is only valid if you never use it for anything.  If it's not dishwasher safe, I'm out.
<bot>: I'm an idiot who screwed up a $90 pan, but I think I might have fixed it to some extent.  Posting this so maybe other people learn from my mistakes.
