Maintaining a clean dishwasher helps improve efficiency, prevent odors, and extend the life of the appliance. Baking soda is a safe, inexpensive option that can tackle grime and buildup when used correctly. This guide explains a straightforward method and offers practical tips for best results.
Quick Answer
Do this routine once a month to keep residues under control: sprinkle baking soda inside the tub, run a hot empty cycle with no dishes, and use a dedicated cleaning brush for stubborn spots.
What You’ll Need
- Dishwasher cleaning brush silicone or a flexible scrub brush
- Dishwasher interior cleaning brush for tight corners
- Dishwasher cleaning kit baking soda (baking soda sized for interior use)
- Dishwasher tub scrub brush for racks and seals
- Dishwasher rack cleaning tool sponge for basket and rack surfaces
Before You Start
Before cleaning, ensure the dishwasher is cool to the touch. Remove racks to access all surfaces. Use gloves if you have sensitive skin. Do not mix baking soda with vinegar inside a running dishwasher, as this can cause foaming and leaks. Plan for a 60–90 minute window to complete the full cleaning cycle and spot scrubbing.
Step-By-Step: How To Clean A Dishwasher With Baking Soda
- Clear the dishwasher Remove racks and any debris from the bottom to ensure full access.
- Inspect seals and corners Check the door gasket, around the spray arms, and the tub seams for mold or grime.
- Wipe loose grime Use a damp cloth or the dishwasher interior cleaning brush to wipe away visible residue from the tub walls.
- Apply baking soda Sprinkle baking soda evenly across the bottom of the tub. Avoid creating clumps that could clog the drain.
- Clean spray arms Use a dishwasher tub scrub brush to dislodge mineral deposits from spray arms and jets.
- scrub door and seals Gently scrub the door edges and gasket with a dishwasher interior cleaning brush to remove mold or slime.
- Run a hot empty cycle Run a standard wash on the hottest setting with no dishes to activate baking soda and flush loosened residue.
- Rinse and repeat if needed If odor or residue remains, repeat the cleaning cycle or spot scrub stubborn areas with a dishwasher rack cleaning tool sponge.
- Clean the racks While the cycle runs, wipe rack surfaces with the sponge and rinse thoroughly before returning them to the dishwasher.
- Final wipe-down After the cycle completes, wipe the tub dry to deter new buildup and inspect for any remaining spots.
- Reassemble Place racks back and run a brief cold rinse to ensure everything is clear before loading dishes normally.
Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Foul odor after cleaning | Residual food particles | Run another hot cycle with baking soda alone | Regular monthly cleaning |
| Visible soap or powder residue | Too much baking soda or improper rinse | Use less baking soda, run final rinse | Measure baking soda for interior use |
| Clogged spray arms | Mineral buildup | Clean jets with interior cleaning brush | Inspect arms during routine cleanings |
| Door gasket feels sticky | Mold or slime | Wipe with brush and a mild cleaner | Keep door slightly ajar after cycles to dry |
| Uneven cleaning | Blocked spray or dirty filters | Clean filters and spray arms thoroughly | Inspect during each cleaning cycle |
Common Mistakes
- Using vinegar with baking soda inside the dishwasher can cause foaming and potential leaks.
- Overloading the tub or blocking spray arms during cleaning reduces effectiveness.
- Skipping the final rinse can leave gritty residues on dishes when normally used.
- Relying on a single cleaning session without routine maintenance allows buildup to return quickly.
Tips For Best Results
- Run the hottest possible cycle for best cleaning action with baking soda.
- Target seals, corners, and jets with the dedicated brushes for a thorough scrub.
- Schedule a monthly maintenance step, especially in areas with hard water.
- Consider a baking soda-based cleaning routine in tandem with a dishwasher cleaning kit for built-in residue removal.
Call A Professional
Stop signs to call a pro include persistent foul odors after repeated cleanings, unusual noises during cycles, visible mold growth, or standing water in the bottom after a wash. If seals or gaskets appear damaged, or if water leaks from the door, contact a licensed technician for inspection and replacement parts.
