Between washes, residues might lead to malodour developing in the dishwasher. This Finish freshener has a unique Scent Control technology designed to give a refreshing clean, fresh scent every time the dishwasher is opened, helping to avoid any fragrance transfer on dishes during the wash. Simply clip the freshener onto a rack or hang it from the upper rack of the dishwasher, without it blocking the spray arms. Once the liquid inside disappears (approximately 60 washes) , replace the whole gadget.
