You can get a new one... but unless yours is really stained up i would not as its a real pain to get to fit right even though its pre molded.

As far as stains and the smell there are a few things you can do. If you really want it done right you can have someone steam clean/shampoo it.

If not i would suggest plenty of resolve and diluted woolite scrub in throughly and pat dry with clean towels. Then use some baking soda and let it sit there and vac. it off.
