Yes, that's exactly right. Some water marks are fine, I have to scrub everything every month or 2, the water here is awfully hard. So I do this:
spray some water
scrub like Cory said
wipe with papertowel, spray some more water, wipe it clean
take my very much loved zilla terrarium cleaner, spray it, wipe to dry, like you would with windex.
done.

edit - and im pretty sure OP could not care less, the thread is 3 y old lol
