Between wash cycles, food residues on dishes can lead to unpleasant odors in your dishwasher. Finish Dishwasher Deo neutralizes unpleasant smells and provides a fresh scent. The unique anti-odor technology ensures that fragrance is only released between individual wash cycles, so the deodorant scent does not transfer to the dishes. Finish/Calgonit is the most recommended brand by leading dishwasher manufacturers.
