My bottle of Finish rinse aid just ran out, I have vinegar under my hand. What happens if I use it as rinse aid with the detergent?

Vinegar as a rinse aid has pros and cons:

Though mild, vinegar can dissolve mineral deposits and leave dishes spot-free. Vinegar is also a good substitute for Finish rinse aid when it runs out because most households have it.

Vinegar may have drawbacks. It can help, but dedicated rinse aids may be better at water sheeting and preventing water spots, especially in hard water areas. Vinegar can also degrade dishwasher rubber seals, making it an unsuitable rinse aid substitute.

For vinegar rinse aid, dilute it with water (1 part vinegar to 3 parts water) and fill the dispenser. It should only be used for a few cycles and then replaced with Finish Rinse Aid for optimal performance and dishwasher health. For long-term use, use a dishwasher-specific rinse aid like Finish Rinse Aid, which is rubber seal-safe.
