I use simple green but yeah give the chain a good thorough cleaning with a grundge brush or better yet steel wool (or a metal bristled brush)...
If it comes off, great...
If not, next thing you could try is removing it for a more thorough cleaning.
Lastly, how many miles on the sprockets (you say 1000 on the chain)? Sprocket and chain set is pricey but just a chain shouldnt be TO bad but yeah I know in college every dollar counts...
But definetly clean it before jumping on a new chain and spending your hard earned cash.
