After the paste has sat, use the soft-bristled brush or sponge to scrub the plastic thoroughly. Focus on areas where mold is visible or where the smell is strongest. The mild abrasiveness of baking soda helps remove mold spores and surface stains without scratching the plastic. Scrub in circular motions, applying gentle pressure to ensure the paste reaches all crevices and textured surfaces. This step is crucial for both cleaning and deodorizing the plastic item effectively.
Once you’ve scrubbed the item, rinse it thoroughly with warm water to remove all traces of the baking soda paste. Ensure no residue remains, as it could leave a white film on the plastic. After rinsing, dry the item completely with a clean cloth or allow it to air dry. Proper drying is essential to prevent moisture buildup, which can lead to recurring mold issues. For best results, leave the item in a well-ventilated area or under direct sunlight, as UV rays can further help eliminate any remaining mold spores and odors.
To enhance the effectiveness of the Baking Soda Scrub Technique, consider repeating the process if the mold smell persists. Additionally, you can combine this method with other natural deodorizers, such as white vinegar, for added odor-fighting power. Simply soak the plastic item in a mixture of equal parts water and vinegar after the baking soda scrub, then rinse and dry thoroughly. This dual approach ensures both the mold and its associated smell are completely eradicated, leaving your plastic items fresh and clean.

Let the hydrogen peroxide sit for at least 10 minutes to give it time to break down the mold and eliminate the odor. For heavily affected items, you may need to leave it for up to 30 minutes. During this time, the hydrogen peroxide will bubble and foam, which is a sign it’s actively working to kill the mold.
After the waiting period, use the soft-bristled brush or sponge to gently scrub the plastic. This action helps dislodge any remaining mold spores and ensures the hydrogen peroxide reaches all crevices. Pay special attention to textured or hard-to-reach areas, as mold tends to thrive in these spots. Once you’ve scrubbed the item thoroughly, rinse it with warm water to remove any residue. Be sure to rinse it completely, as leftover hydrogen peroxide can cause discoloration or damage over time.
For persistent mold smells, repeat the hydrogen peroxide treatment. After rinsing, inspect the item to ensure the odor has been neutralized. If the smell remains, reapply the hydrogen peroxide and let it sit for another 10–15 minutes before scrubbing and rinsing again. Once the mold and odor are gone, dry the plastic item thoroughly with a microfiber cloth. Air-drying is also recommended to ensure no moisture remains, as dampness can encourage mold regrowth.
Finally, store the cleaned plastic item in a dry, well-ventilated area to prevent future mold issues. Hydrogen peroxide is not only effective for immediate cleaning but can also be used as a preventive measure. Periodically spraying plastic items with a diluted hydrogen peroxide solution (1 part peroxide to 2 parts water) can help keep mold at bay. This method is safe for most plastics, but always test a small area first to ensure it doesn’t cause discoloration or damage. With its powerful cleaning and deodorizing properties, hydrogen peroxide is a reliable choice for tackling mold smells on plastic.
