what is rinse aid for dishwasher

Rinse aid is a drying agent that helps improve dishwasher drying performance and reduce water spots on dishes. It contains chemicals called surfactants, which lower the surface tension of water, making it easier for water to slide off dishes in the dishwasher. Rinse aid helps prevent water spots from forming on glasses, plates, and cutlery, and it also helps dishes dry faster. Rinse aid is typically added to a designated compartment in the dishwasher, usually located next to the detergent dispenser. It is recommended to use rinse aid in your dishwasher for best results, as it assists drying performance and can help reduce water spots and filming. Without it, your dishes and dishwasher interior could have excessive moisture. However, if you have soft water, your glasses are spot-free, and you are satisfied with your dishwashers drying abilities, you can do without a rinse agent.
