You can also try using bleach to scrub it-the bleach will dissipate and as long as you rinse it, many many times, and let it air out it will be fine.
As Shawn said-then use Listerine-we use it to clean all our burm cages for everyday cleaning. Use the "brown death flavor". We keep it in one of those big sprayer things they use for gardening and dilute it with a bit if water-works great!!!
