If anyone has a method I would love to hear it.

I may have let some fish scraps marinate a little longer than I had intended in one or two of our coolers. Wife was after me to get it dumped but I am nose blind to such things and frankly I was having a good time with it. Every time she mentioned it I thought I would wait just a little while longer to get it dumped out. She wasn't happy. I washed them out well and filled them to the top with strong bleach water yesterday and let them sit all night.

This am they are still funky fishy smelling.

You guys have a sure fire method for getting the smell out of cooler?
