These marks in your pan are normal for stainless steel. I have some stainless steel pans I use and I wash then as I would my other pans (except iron) and try not to worry to much about marks such as you have. If you scrubbed the pan and you still see them I figure its a stain and not really "dirty" per say.
The first time I noticed bad stains in my stainless steel was in my pasta pot. Remember to never add salt to your pasta water until after it boils. Salt takes its toll from a stainless pan but it is all cosmetic. I recently acquired a set of Allclad stainless that I like a lot and have used Calfalon (sp?), which I love, but it is fairly expensive to purchase (my birthday is in May ;-)).
I wouldn't sweat the stains to much but keep in mind salt and stainless do not always play well together.
Good luck and keep the faith,
What if the the Hokey Pokey IS what it is all about?
