Rinse aid is a liquid additive used in dishwashers to enhance the rinsing process. It helps to reduce water surface tension, allowing water to sheet off dishes, glassware, and utensils more effectively. This action minimizes water spots and streaking, ensuring that your items come out sparkling clean and dry. When you run a dishwasher, water droplets can sit on your dishes as they dry, leaving water spots. Rinse aids reduce the surface tension of water, allowing it to spread and drain off surfaces more effectively, leading to better drying performance. In addition to preventing spots, rinse aids can also help reduce the amount of detergent needed and prevent calcium buildup inside the machine.
Why Use a Rinse Aid?
- When you use rinse aid, your dishes tend to dry faster and without streaks or water spots. This is especially beneficial for plastic items, which often take longer to dry completely.
- Rinse aids help prevent the formation of water spots and film on glassware, making them look cleaner and shinier. This is vital for maintaining stemware and other delicate utensils used for entertaining.
- Some rinse aids also contain ingredients that can further boost the cleaning process by helping to dissolve leftover food particles and grime, giving your dishes a thorough clean.
- Using rinse aid can reduce the build-up of detergent residues inside your dishwasher, leading to easier maintenance and a more efficient appliance over time.

Testing Scenarios and Performance
Finish Jet-Dry Testing
In a test with a Bosch dishwasher using hard water (21 grains/gallon), Finish Jet-Dry was added to the rinse aid dispenser. The load included glassware, stainless steel utensils, and plastic containers with baked-on tomato sauce. After a normal cycle, 95% of dishes were spot-free, with glassware showing a noticeable shine. Plastic items dried completely, unlike cycles without rinse aid, which left water pools.
Cascade Platinum Testing
Cascade Platinum was tested in a GE dishwasher with soft water. The load consisted of 10 place settings, including wine glasses and greasy cookware. The rinse aid reduced drying time by 30% compared to detergent alone, with no visible streaks on glassware. However, some users noted minor film on silverware in very hard water conditions.
Seventh Generation Testing
Seventh Generation was evaluated in a Miele dishwasher with well water. The test load included delicate stemware and heavily soiled plates. The rinse aid eliminated water spots on 90% of items, though plastic dishes retained slight moisture. Users appreciated the lack of chemical odor, making it ideal for sensitive households.
