Oh, sure, blame everything on poor hubby!

I've always had good luck with vinegar and water. It's probably seeped down into the pad, though, so it's tough to get out. I've heard people recommend fabreeze. I just googled and someone recommended baking soda:

Baking soda “adsorbs” odors, which means it takes odors from the air. It neutralizes acid-based odors in water.

Liberally sprinkle baking soda on the carpet. Let set overnight, or as long as possible (the longer it sets the better it works). Sweep up the larger amounts of baking soda, and vacuum up the rest. (Note that your vacuum cleaner bag will get full and heavy.) Redo the process if you still smell odors you wish to remove. Baking soda works like magic, it sometimes just takes time and making sure you are using enough baking soda.

Caution: While damp baking soda works really well for many odors, damp baking soda can also get stuck onto the carpet fibers and be difficult to clean. If you live in a very humid climate you might substitute a light spray of white distilled vinegar for the baking soda.
