vinyl/roof Cleaners...

Hi everyone, I'm kind of new here. I tried searching previous threads for an answere to my question, but coudnt find any. If I missed it please don't flame.

I want to know from those who have vinyl seats, what is the best cleaner/restorer? I've heard some bad things about Armor All... I don't want my seats drying out or anything. :P

Also, can anyone recomend something for cleaning the interior roof? Like a shampoo or something like that. For some odd reason the previous owner got it a little dirty.
