Simply fill your machine's rinse aid compartment with Finish Jet-Dry 3-in-1 to solve three problems at once—it rinses, dries, and shines what detergent alone can’t! Rinses away leftover food and film. Dries left behind water droplets. Clears spots for a brilliant shine. Easy to use, simply refill the rinse aid compartment every few weeks, not every wash.
