you must do it right away when you get back from the grocery store. put the whole carton in a bowl of like 75% water 25% white vinegar. let it sit for like 15-20 min then strain and rinse. let them dry on a paper towel then put into a berry basket or bowl in the fridge! do not put back into the original container!!! anyway, it kills all the mold spores and gets off all the little microbes and dirt. the berries last like 100000 x longer and don’t get moldy
