Finish All-in-one dishwasher tablets are designed to simplify the dishwashing process by combining detergent, rinse aid, and salt into one convenient product. In areas with soft or moderately hard water, these tablets often perform well without the need for additional salt. However, if you live in a region with hard water, the built-in salt may not be sufficient. Hard water causes limescale build-up, which can affect your dishwasher’s performance and leave white spots on dishes and glassware(1). Dishwasher salt plays a vital role in softening water and preventing the mineral deposits responsible for these spots.
Do you need to use dishwasher salt with Finish all-in-one tablets? No, but depending on your area, your water hardness levels may exceed the capacity of the salt in your all-in-one tablets. In this case, using extra dishwasher salt will enhance cleaning results and protect your machine. Many modern dishwashers have indicators for low salt levels, which can help you decide whether extra dishwasher salt is necessary. To ensure the best results, check your local water hardness and consult your dishwasher’s manual to maintain both the cleanliness of your dishes, and lifespan of your appliance.
