The instructions for my Finish dishwasher tablets don't mention using a rinse aid. How necessary is it?

Rinse aid can improve dishwashing even if your Finish dishwasher tablets don't recommend it openly. Rinse aid helps dishes dry by letting the water sheet off during the final rinse. This reduces water spots, streaks, and film, leaving dishes sparkling clean and dry. Rinse aid improves water flow, reducing mineral deposits and detergent residue on dishes. Rinse aid may improve dishwasher detergent cleaning, including Finish tablets.

When using Finish tablets, a rinse aid is recommended but not required for dishwasher operation. Rinse aid can boost drying, reduce water spots, and improve cleaning. Therefore, even if not explicitly stated in the instructions, adding rinse aid to your dishwashing routine can improve results.
