What should i use for cleaning up my car?

i'm not sure which category this goes in, but i wanna clean up my car (it's used, just bought it at an auction, getting fixed tomorrow, wanna clean it tonight.) i need to get bird crap off the trunk (outside) and there's the sticky stuff from a sticker on the windshield, wasnt sure what to do about that. It's not like little bits of paper or anything, just the adhesive that makes it stick there. I also wanna know what kind of cleaner to use for the interior (seats and such). It's a Chevy Lumina 95'.
