Wash with Dish Soap: Use hot water and dish soap to break down oil residue on plastic surfaces
One of the most effective and straightforward methods to eliminate fish oil smell from plastic is to wash with dish soap. Dish soap is specifically designed to cut through grease and oil, making it ideal for breaking down the oil residue that causes the lingering odor. Start by filling your sink or a large basin with hot water, ensuring it’s as hot as you can safely handle, as heat helps to dissolve the oil more effectively. Add a generous amount of dish soap to the water, creating a soapy solution that will tackle the grease. Submerge the plastic item completely, allowing it to soak for at least 15-20 minutes. This soaking period gives the soap and hot water time to penetrate and loosen the oil residue.
After soaking, use a sponge, brush, or scrubber to scrub the plastic surface thoroughly. Focus on areas where the oil may have accumulated, such as crevices or textured surfaces. The mechanical action of scrubbing, combined with the dish soap, will help lift away the oil particles. Pay extra attention to any visible stains or greasy spots, as these are likely the source of the odor. If the item has a lid or removable parts, disassemble it and clean each piece separately to ensure no area is overlooked.
Once you’ve scrubbed the plastic, rinse it thoroughly with hot water to remove any soap residue and dislodged oil. It’s important to rinse well, as leftover soap can leave a film or taste on the plastic. After rinsing, inspect the item for any remaining odor or grease. If the smell persists, repeat the process, increasing the soaking time or using a stronger dish soap formulation. Some dish soaps are specifically labeled as "grease-fighting," which can be particularly effective for stubborn fish oil residue.
For added effectiveness, consider adding baking soda to the dish soap solution. Baking soda is a natural deodorizer and can enhance the cleaning power of the soap. Mix a few tablespoons of baking soda into the hot water before adding the dish soap, then proceed with the soaking and scrubbing steps. This combination can be especially useful if the fish oil smell is particularly strong or has been present for a long time.
Finally, after cleaning, air-dry the plastic item completely in a well-ventilated area. Avoid using towels or cloths to dry it, as they may transfer new odors or lint. Allowing the item to air-dry ensures that no moisture is trapped, which could lead to mold or mildew and exacerbate the smell. Once dry, inspect the plastic again to confirm the odor has been eliminated. If done correctly, washing with dish soap and hot water should effectively remove fish oil smell from plastic, leaving it clean and odor-free.

Scrub thoroughly for at least 2-3 minutes to ensure maximum effectiveness. This step is crucial, as inadequate scrubbing may leave behind traces of oil, allowing the smell to persist.
After scrubbing, let the baking soda paste sit on the plastic for about 10-15 minutes. This waiting period allows the baking soda to fully absorb and neutralize the odors. During this time, the paste will dry slightly, making it easier to rinse off. Once the time has passed, rinse the plastic item thoroughly under warm running water. Ensure all traces of the baking soda paste are removed, as any residue could leave a white film on the plastic. Proper rinsing is essential to avoid a new, unwanted smell or texture on the item.
For particularly stubborn fish oil smells, repeat the Baking Soda Scrub process a second time. The first application may significantly reduce the odor, but a second round can ensure complete neutralization. After the final rinse, allow the plastic item to air dry completely before using or storing it. This method is not only effective but also safe for most plastic items, making it a go-to solution for removing fish oil smells without harsh chemicals.
In summary, the Baking Soda Scrub method is a simple, natural, and efficient way to remove fish oil smells from plastic. By mixing baking soda with water, scrubbing the plastic thoroughly, and rinsing it clean, you can neutralize odors and restore the item to its original state. This approach is particularly useful for kitchen items like containers or utensils that have absorbed fish oil smells over time. With its accessibility and effectiveness, the baking soda scrub stands out as a reliable solution for this common household challenge.
