Some effective ways to remove bad odor from a dishwasher include checking the filter for obstructions and cleaning it, sprinkling baking soda into the bottom of the dishwasher between uses, and by substituting rinse agents with vinegar. Using less detergent helps prevent bad odors from developing.
Citrus acid is also used to effectively remove bad odors from dishwashers. Homeowners can apply 3 to 4 tablespoons of citrus acid to the bottom of the dishwasher. For more obvious odors, more citrus acid is effective. Run the dishwasher using the hottest setting and stop the cycle before the water drains. It's important to let the water and citrus acid mixture sit for a few hours, and then the cycle can be finished.
There are several ways to use baking soda to help eliminate bad odors from a dishwasher in addition to the one mentioned. Sprinkling baking soda on top of the dishes before running the wash cycle helps eliminate all odors. Additionally, using a homemade baking soda detergent also eliminates bad odors that have developed.
To make homemade baking soda dishwasher detergent, 2 tablespoons of baking soda are mixed with 2 tablespoons of borax powder. The mixture is put into the detergent compartment. Homeowners may need to alter the recipe to fit the size of the compartment.
