Finish Dishwasher Cleaner works by safely and 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 and vital parts: filters, spray arms and pipes. Use Finish Dual Action Dishwasher Cleaner with 5X Powers once a month for an amazingly clean, fresh and well-maintained dishwasher. A cleaner dishwasher means cleaner dishes!
