Nail polish remover is acetone. Acetone can vary in purity and may or may not leave a residue.
You say you filled it up. You mean with water, as in to rinse it out?
Personally, I like to do a final wipe-down with rubbing alcohol after working on my vivs.

How do you do this "wipe down" ?? And what is it that you are "wiping down?"
