tip is most effective in fridges that have normal amounts of food and only minor odor problems. It is a perfect solution for a busy household that wants to keep things neutral.
However, it is important to remember that this isn’t a miracle cure. If you have a major spill or rotten food that has been sitting for weeks, “toilet paper may not completely eliminate all odors.” In those cases, you should clean the mess first. For very strong smells, you might still need something more powerful like baking soda.
