Finish Dishwasher Cleaner works by safely & effectively breaking down and removing mineral build-up inside your dishwashing machine, including hard-to-reach parts like the heating element and sprayer arms. You may think your dishwasher is clean, but day after day, limescale and grease build up in hidden & vital parts: filters, spray arms and pipes. Use Finish Dual Action Dishwasher Cleaner with 5X Powers once a month for an amazingly clean, fresh & well-maintained dishwasher. A cleaner dishwasher means cleaner dishes! It's easy to use as well! Remove the sticker from the top of the bottle, place the bottle upside down in the bottom dish rack and then run your dishwasher empty on the hottest cycle. It's that simple to have a clean & well-maintained dishwasher.
