Clean your dishwasher monthly with vinegar and baking soda to prevent odors and buildup.
- Always separate vinegar and baking soda into different cycles for maximum effect.
- Regular maintenance, like cleaning the filter and wiping the gasket, extends the life of your dishwasher.
Why does my dishwasher smell or have buildup?
Food particles, grease, and hard water minerals accumulate over time. These create a film on interior surfaces and a musty odor. The drain filter and spray arms often trap debris. Detergent residue can also build up if you use too much. Hard water leaves white scale on the tub and heating element. These deposits reduce cleaning performance and can clog parts.
How to clean a dishwasher with vinegar and baking soda step by step
First, empty the dishwasher completely and remove the bottom rack. Check the drain and filter for large food pieces and remove them by hand. Place a cup or bowl of white vinegar on the top rack. Run a hot water cycle, but pause it halfway to let the vinegar sit for 15 minutes. After the cycle finishes, sprinkle one cup of baking soda across the bottom of the tub. Run a short hot water cycle. Finally, wipe the door gasket, edges, and control panel with a vinegar-dampened cloth. This method removes odors, grease, and light scale.
How to prevent dishwasher smells and buildup
Scrape food off dishes before loading, but there is no need to rinse. Run the dishwasher at least once a week to prevent stagnant water. Clean the filter monthly to remove trapped debris. Use a rinse aid to reduce spotting and film. Check the spray arms for clogs and clear them with a toothpick. Leave the door slightly ajar after a cycle to let moisture escape. Avoid using too much detergent; follow the manufacturer's dosage.
When should you call a pro or replace the dishwasher?
If the dishwasher still smells after cleaning, there may be a clog in the drain hose or a broken seal. Persistent leaks or error codes require a technician. Strange noises or failure to drain are also signs of a bigger issue. If the unit is over 10 years old and needs frequent repairs, replacement is often more cost-effective. Always disconnect power before inspecting internal parts.
