Overview
- Argentine outlets published renewed guidance May 25–26 recommending a simple overnight fix of about half a cup of baking soda in a shallow open container placed inside an unused microwave.
- The method works because sodium bicarbonate absorbs moisture and chemically neutralizes odor-causing particles rather than merely masking smells.
- Reporters and cited specialists say the trick is safe and non‑toxic and leaves no harmful vapors or residues inside the appliance.
- Coverage stresses that the baking soda treatment complements routine cleaning and filter maintenance and will be temporary if food spills, burned splatters or saturated extraction filters are not removed first.
- Experts advise wiping the interior with warm water or a mild water-and-vinegar solution before use and repeating the overnight treatment for persistent odors.
