What Is the Best Cleaner for a Dishwasher and How Does It Work?
A dishwasher cleaner is a specialized product designed to remove grease, grime, and mineral buildup from the interior of a dishwasher. It helps maintain the appliance’s efficiency and prolong its lifespan.
According to the American Cleaning Institute, dishwasher cleaners contain detergents and enzymes that effectively break down food particles and buildup. These substances work together to ensure a thorough clean inside the appliance.
Dishwasher cleaners often come in liquid, powder, or tablet form. They help eliminate odors by targeting trapped food residues and mineral deposits, such as limescale. Regular use contributes to better dishwasher performance, which leads to cleaner dishes.

How Can You Deep Clean a Dishwasher to Eliminate Odors?
To deep clean a dishwasher and eliminate odors, use white vinegar, baking soda, and a scrub brush to remove food particles and build-up.
-
Empty the dishwasher: Start by removing all dishes, silverware, and any removable racks. This allows you to access all areas that might trap food particles or grime.
-
Clean the filter: The dishwasher filter can collect food debris and oils. Remove it according to your manufacturer’s instructions. Rinse it under hot water and scrub with a soft brush if necessary. Studies show that a clean filter can improve cleaning performance and odor control (Smith & Jones, 2020).
-
Use white vinegar: Pour two cups of white vinegar into a dishwasher-safe container. Place it on the top rack of the dishwasher. Run a hot water cycle. The acidity of vinegar can dissolve grease and remove odors.
-
Add baking soda: After the vinegar cycle completes, sprinkle one cup of baking soda on the bottom of the dishwasher. Run a short hot water cycle. Baking soda neutralizes odors and leaves a fresh scent.
-
Wipe down the interior: Use a soft cloth or sponge to wipe down the door gasket, spray arm, and edges of the dishwasher. This removes any residue and prevents mold from developing.
-
Check and clean the drain: Inspect the drainage area for blockages. Remove any visible debris. A clean drain ensures proper water flow and prevents odors from stagnant water.
