Bleach vs vinegar vs baking soda for cooler cleaning: Bleach wins for killing mold fast

Bleach kills mold dead, leaves no residue, and won’t stain plastic — just dilute one tablespoon per quart of water, scrub, let sit five minutes, then rinse. White vinegar works in a pinch but takes longer and smells. Skip baking soda: it’s a mild abrasive that doesn’t kill spores.
