Written By James Morgan
Barbecue enthusiasts and home cooks alike often rely on their trusty rice cookers to produce perfectly fluffy rice. However, encountering a plastic smell coming from your rice cooker can be off-putting and concerning. So, why does my rice cooker smell like plastic? In this in-depth guide, we will explore the reasons behind this issue and provide effective solutions to ensure you can enjoy great quality rice without any unwanted odors.

The Culprit Behind the Plastic Smell
Understanding the reason behind the plastic smell in your rice cooker is the first step to resolving the issue. This problem can arise from multiple sources, and addressing it requires a thorough examination of various factors.
Rice Cooker Must-Haves (Accessories & Tools)
New Rice Cooker
If you've recently purchased a new rice cooker, the plastic smell might be due to the manufacturing process. When a new appliance is made, certain materials used, such as plastic parts, can release volatile organic compounds (VOCs) that cause the plastic smell. This is commonly referred to as 'off-gassing.'
Improper Cleaning
Another common cause is improper cleaning of the rice cooker. Food residue or cooking liquids can leave a lingering odor. Over time, if these residues are not cleaned properly, they can emit a plastic-like smell during cooking.
How to Eliminate the Plastic Smell

Now that we've identified the common reasons, lets look at actionable steps you can take to eliminate the plastic smell from your rice cooker.
Initial Cleaning for New Cookers
For new rice cookers, a thorough initial cleaning can help reduce or eliminate the plastic smell. Start by washing all removable parts with warm soapy water. Fill the cooker with water and add a tablespoon of white vinegar. Run a cooking cycle with this mixture, then rinse thoroughly.
Regular Maintenance
Regular cleaning and maintenance are essential to prevent any residual smells. Be sure to clean the inner pot, lid, and other accessories after each use. You can use a mixture of baking soda and water for a more thorough cleaning, which can help neutralize odors.
Air Out the Cooker
After cleaning, leave the rice cooker open to air dry completely. This helps any remaining VOCs or odors dissipate. Keeping the lid open when the rice cooker is not in use can also prevent smells from forming.
Additional Tips and Tricks

Here are some additional tips that might help you maintain a fresh-smelling rice cooker:
- Use a lemon water solution: Boil a mixture of water and lemon juice in the cooker.
- Charcoal: Placing a piece of charcoal inside the cooker when its not in use can help absorb odors.
Using the Rice Cooker Properly
Ensuring you use the rice cooker according to the manufacturers instructions can also make a difference. Avoid overfilling the cooker and use the appropriate settings for different types of rice.
