Editor's Pick: Over time, dishwasher spray arms and interior walls build up a layer of limescale and grease film, leaving dishes with a lingering odor after washing. Just place this bottle upside down on the bottom rack and run an empty hot water cycle — it clears out grime from spray arm holes, the filter, and the pipes. Use it once every three months, and when you open the door after a wash, there's no weird smell, and dishes rinse cleaner too.
