Streaks or Spots
Mineral deposits from hard water can leave white streaks or spots on your dishware. Add a water softener, and use your dishwasher’s rinse aid feature – making sure it’s adjusted to your water’s mineral levels. Using hard water cleaner every two months can also help eliminate residue buildup.
Rack Doesn’t Roll
