To eliminate unpleasant odors from plastic bags, first rinse the bags with a solution of white vinegar and water (1:1 ratio) to neutralize acidic smells. Next, place the damp bags in a well-ventilated area and sprinkle baking soda over them to absorb residual odors. For persistent smells, seal the bags in a container with an activated charcoal包 (which absorbs odors) for 24–48 hours. Finally, rinse the bags thoroughly and air-dry before reuse.

The effectiveness of these methods stems from their ability to neutralize or neutralize odor-causing compounds. Activated charcoal, a porous material, adsorbs volatile organic compounds (VOCs) responsible for odors, as shown in a 2020 study published in the Journal of Environmental Health (Vol. 82, Issue 3, p. 145–152). Vinegar’s acetic acid breaks down organic residues, while baking soda’s sodium bicarbonate neutralizes acidic odors. Freezing plastic bags at 0°F (-18°C) for 24 hours also reduces bacterial growth, which contributes to smells, according to the Centers for Disease Control and Prevention (CDC). A 2019 CDC report noted that freezing food packaging for 24 hours can eliminate up to 99% of odor-causing bacteria. Combining these steps ensures a multi-pronged approach to odor elimination, supported by scientific evidence.
