Ack! Did my houseguests ruin my AllClad LTD cookware set?!!

I have a set of AllClad LTD pots/pans. A while back we had some
houseguests that were here helping us when our first child was born.
They used the AllClad for cooking and also cleaned them after. They
scratched the insides of all the pots and pans with who knows what.
If you shine them in the light you can see all the scrub marks on the
bottom and sides from when they were cleaned. When I rub my finger on
them you can't feel them, nor can you feel the scratches if you run
your fingernail across them. Are these things ruined or can I get my
mirror finish back? I'd like to buy something kind of polish, sit
down, and get these things back to the way they were when I bought
them.

I was very distressed tonight when I learned they were all scratched
up like this.

Also, why doesn't AllClad want you to put these LTDs in the dishwasher
anyways?

Thank you for your time in helping me, I sure will appreciate all
responses.

Thanks again,

-Jaime
