Hi, Jackie. Our Finish Quantum Tabs provide the ultimate clean, shine, and film protection. Its three separate fast-dissolving chambers deliver three power actions: break down and lift tough messes, grease-cutting power, and a finishing boost of shine. The white residue you describe sounds like it could possibly be from hard water buildup. Using Finish Jet-Dry Rinse agent will help water sheet off dishes, leaving fewer water spots, filming and allowing dishes and glassware to dry more quickly. We hope this information helps. As the manufacturer of Finish, we'd like an opportunity to speak with you personally to further assist you. Please call 1-800-235-6052 between 9:00-5:00 EST (Monday - Friday) or send us an email via the Contact Us page on our website and someone will be happy to help you. When calling or emailing, kindly refer to case number RB0001101289. Sincerely, Your Finish Team! https://www.samsclub.com/p/finish-jet-dry-ultra-rinse-aid-dishwasher-rinse-agent-drying-agent-32oz/prod22930894?xid=plp_product_1
