22:Refresh Tupperware
Even if you clean Tupperware after every use, if you store it with the lid on, you may notice that they start to smell old and used. Since nobody wants to store food in something that smells bad, this is a problem but it doesn’t require buying a new set of Tupperware.
For a quick solution, brush the inside with toothpaste and let it sit for a few minutes before rinsing it out. Then, store with the lid off.
