I would go with the Arm and Hammer too.
A couple of years ago we caught 15 bluegills and we only cleaned 14. Accidentally missed one taking them out of the livewell. After one week of the boat sitting in the hot garage in August, I started smelling something in the garage. OH MY GOD can one rotting fish smell!!!
Anyway, Arm and Hammer, alot of water, and some elbow grease got the smell out after some work.
PS, a bluegill turns to skeleton and mush after one week in a 90+degree garage.
