eah I have been there and done that and it sucks....BIGTIME. It took a whole offseason for the stench to fade even after constant rinsing
. About 10 years ago I was the Tournament director for my club. WE had a tourney on Champlain and i wanted to be sure the smallies were released into deep water. Myself and another boat were "runners". We had everyone dump their fish into our livewells and we ran them out to the deeper cooler water. Well I must have missed one

Like you, a month later I pulled the cover off my boat and the smell knocked me over
Be careful of what you put into your livewell to clean it. Any residue left behind can be deadly to the bass.
