Taking the time to clean your dishwasher regularly not only ensures cleaner dishes but also helps you avoid costly repairs down the line.

Maintaining a Fresh Dishwasher

Cleaning your dishwasher with bleach is crucial, but regular maintenance is key to keeping it fresh and odor-free. Here are some practical tips to ensure your dishwasher stays in top condition:

  • Clean the Filter: Check and clean the dishwasher filter regularly to prevent food particles from clogging the drain and causing unpleasant smells.
  • Wipe Down Seals and Edges: Use a damp cloth to wipe down the door seals and edges to remove any food residue or grime that might harbor bacteria.
  • Run Hot Water Before Starting: Before running a cycle, let the hot water tap run for a few minutes to ensure the water entering the dishwasher is hot enough to clean effectively.
  • Use Citrus Peels: Place a few citrus peels (like lemon or orange) in the utensil basket each month and run a cycle with no dishes to keep your dishwasher smelling fresh naturally.
  • Regular Inspections: Periodically check for any leaks, unusual noises, or issues with the spray arms to address them promptly and prevent further damage.
