Leaving rice in a rice cooker for an extended period—especially while traveling abroad—can lead to an unpleasant surprise upon your return. Instead of finding fluffy grains, you may be met with a moldy, stringy mess accompanied by a pungent, musty odor. This situation not only makes the rice cooker unusable but also presents a major cleaning challenge.
If you’ve ever opened your rice cooker after weeks of neglect and discovered moldy, rotting rice, don’t panic! With the right cleaning techniques, you can restore your rice cooker to its original state and eliminate even the most stubborn smells.
Understanding the Problem: Why Rice Cookers Get Moldy
Rice left in a warm, humid environment provides the perfect breeding ground for mold and bacteria. As time passes, mold spores spread throughout the cooker, embedding into the components, causing persistent odors and potential health hazards.
In extreme cases, mold can seep into hard-to-reach areas like the vents, lid, and heating element, making it difficult to remove both the smell and contamination.
Assessing the Damage: Can You Save Your Rice Cooker?
Before you start cleaning, check if your rice cooker is salvageable. If mold has only affected the removable parts, such as the inner pot and lid, you can clean it thoroughly and continue using it.
However, if mold has penetrated the internal electrical components, or if the damage is too severe (such as corrosion or electrical malfunction), you may need to replace the appliance.

Step-by-Step Guide: How to Deep Clean a Moldy Rice Cooker
If your rice cooker is still functional, follow these six essential steps to clean it thoroughly and get rid of the mold and odors.
Step 1: Remove Moldy Rice and Initial Cleaning
- Unplug the rice cooker immediately. Never clean a plugged-in appliance.
- Remove the inner pot and dump the moldy rice into a sealed plastic bag to prevent spores from spreading.
- Rinse the inner pot with hot water to remove loose debris.
Step 2: Deep Cleaning the Inner Pot
- Fill the pot with hot water and white vinegar (1:1 ratio). Let it soak for at least 30 minutes.
- Scrub the pot with a soft sponge or brush to remove any mold residue.
- Rinse thoroughly and air dry completely before reusing.
Step 3: Eliminating Lingering Odors with Baking Soda
- If odors persist, mix 2 tablespoons of baking soda with warm water in the inner pot.
- Let it sit overnight to absorb the smell.
- Rinse well in the morning and allow it to dry.
Step 4: Cleaning the Lid and Vents
- Mold and bacteria often hide in the lid and steam vents, so don’t skip this step!
- Use a small brush or cotton swab dipped in vinegar to clean the vent holes.
- For removable lids, soak them in a vinegar solution, scrub gently, and rinse.
Step 5: Wiping Down the Heating Element and Exterior
- Use a damp cloth with mild soap to clean the heating element and metal surfaces inside the cooker.
- Avoid getting excess moisture near the electrical components.
- For stubborn stains, gently scrub with a baking soda paste, then wipe clean.
Step 6: Reassembling and Testing the Rice Cooker
- Once all parts are dry, reassemble the cooker.
- Fill it with clean water and run a short cooking cycle to remove any remaining residues.
- If the odor persists, repeat the baking soda soak overnight.
Preventive Measures: Avoiding Future Mold Growth
To ensure you never have to deal with moldy rice again, follow these simple tips:
- Never leave cooked rice sitting for long periods. Refrigerate leftovers immediately.
- Always unplug your rice cooker after use. A warm environment encourages mold growth.
- Clean the inner pot and lid after every use. This prevents food buildup.
- Wipe down the inside of the cooker regularly. Moisture can accumulate over time.
- If leaving for an extended period, store the rice cooker with the lid slightly open to allow air circulation.
