DIY Solutions for Removing Film from Dishwasher

If you’re dealing with film buildup in your dishwasher, don’t worry! Here are some easy and cost-effective solutions you can try:

  • Vinegar Rinse: Start by placing a cup of white vinegar in the top rack of an empty dishwasher. Run a hot water cycle to help remove residue and buildup.
  • Baking Soda Scrub: Make a paste using baking soda and water. Apply it to the interior of the dishwasher and let it sit for a while before scrubbing gently and running a short cycle.
  • Lemon Juice Freshen-Up: Cut a lemon in half and rub it on the interior surfaces of the dishwasher. The acidity can help break down film and leave your appliance smelling fresh.
  • Check Water Temperature: Ensure your water heater is set to at least 120°F (49°C) for effective cleaning and to prevent film buildup.
  • Clean Filters and Spray Arms: Regularly clean the dishwasher filter and spray arms to prevent clogs and ensure proper water flow during the wash cycle.
  • Avoid Overloading: Ensuring there’s enough space between dishes allows water and detergent to reach all surfaces effectively, preventing film buildup.

Remember, consistency in maintenance is key to keeping your dishwasher performing at its best and your dishes sparkling clean.
