1. Step 1: Clean the Filter2. Step 2: Vinegar Cycle3. Step 3: Baking Soda Scrub

Step 1: Clean the Filter

Pull out the bottom rack and remove the filter at the base (twist counterclockwise and lift). Rinse it under hot water and scrub with an old toothbrush to remove trapped food particles. This is the number one cause of a smelly dishwasher and most people never clean it.

Step 2: Vinegar Cycle

Place a cup of white vinegar in a dishwasher-safe bowl on the top rack. Run a hot water cycle with the dishwasher empty. The vinegar dissolves mineral deposits, grease, and odor-causing bacteria.

Step 3: Baking Soda Scrub

After the vinegar cycle, sprinkle one cup of baking soda across the bottom and run a short hot cycle. This whitens stains, removes remaining odors, and freshens the interior.

Pro Tips

โœ“Clean the dishwasher once a month
โœ“Wipe the door gasket with vinegar monthly as mold grows there
โœ“Run hot water at the kitchen sink before starting a cycle so the dishwasher fills with hot water from the start
โœ“Never use bleach in a stainless steel dishwasher
