smell

One of my suits is pretty smelly. I've tried rinsing it with water and sun drying it many times to no avail. Tried shampoo, still stinky. Is there any product or solution I could use to give the suit a thorough clean? Baking Soda or something? Many thanks!

First post! Bought a used Atomic B2 and SSI this weekend. Great condition, breathes great. Taking it to LDS for complete checkout before diving with it. The only downside was the previous owner was a smoker, so it has a bit of smokey stink. I'm throwing out the mouthpiece AND low pressure...
