Method 3: Use Sunlight after Removing the Food from Tupperware

Placing the Tupperware in the sun will assist to eliminate intense onion scents. 

Wait for a bright day if your containers are smelling like onions. The containers should then be placed outdoors in the sun.

This is a fantastic option since sunlight has the capacity to naturally eliminate smells (good or bad). As a result, the boxes will have no odor. The odor will be removed by air or breeze, in addition to sunshine. 

Finally, if you leave the Tupperware out in the sun, avoid placing it on the grass. Insects may crawl on it, causing germs to grow.

Vinegar is a natural cleaning agent. Whether you’re cleaning shower tiles without scrubbing or cleaning your Tupperware, vinegar can be really useful. 

You may have already cleaned the containers with dish soap and warm water. But, the onion odor persists. If that’s the case, we recommend filling it with white vinegar. Wait five to ten minutes after adding the vinegar to get rid of the harsh aromas.

Wipe the vinegar from the box and thoroughly clean it with soapy water. Because white vinegar is widely accessible at the supermarket and is very inexpensive. This is an effective way of removing smells.

Baking soda is considered a god among cleaning agents. Whether you’re removing furniture odors or removing bad smells, baking soda works pretty well.
