I have an Engel bait cooler and have used it a year and a half without losing a single minnow. Last week I had minnows dying before I got set up, maybe 30 minutes after buying them. I read to wash it with sea salt and I did that and today by the time I got to the spot to fish 2/3 were dead. If I keep the lid closed it looks like I put bubble bath in it. I bought the minnows at the same store as always and they always have fresh and healthy minnows. I use Better Bait as well
I need some advise on how to wash out the cooler.
