This. It really helps. I consume a lot of berries.

I figured this one out. Rinse in cold water not hot, hot makes bacteria come out to prosper. Cold water hefty rise then close the container and tilt it all around to get excess water out. After that. Let them air dry for a while. Don’t put them back in the wet damp fridge. They now last about 2 weeks. Depending in original ripeness. Heat will ripen faster. Cold water preserves.
