Putting a roll of toilet paper in the fridge sounds strange, but plenty of people swear by this simple hack. The idea works because toilet paper is highly absorbent. Inside your refrigerator, it can soak up excess moisture from the air, which helps reduce humidity and limit mild odors. Some believe the drier environment also helps food stay fresh a little longer.

As the roll absorbs moisture, it may also trap odor particles from foods like onions, garlic, leftovers, or cheese. It won’t eliminate strong smells, but it can take the edge off everyday fridge odors. The trick is popular because it’s cheap and convenient. Instead of buying commercial deodorizers, you just grab a fresh roll you already have at home.

This works best for refrigerators with light odor or moisture issues. It won’t solve serious problems caused by spoiled food, mold, or leaks—those still need a full cleaning. For stronger smells, baking soda or activated charcoal are usually more effective. Place the roll somewhere dry, like a side or top shelf, away from spills and condensation.

Replace the roll every three to four weeks, or sooner if it feels damp or smells stale. Use a clean, unused roll, and don’t let it touch uncovered food. If it becomes wet or moldy, toss it immediately. The toilet paper fridge hack isn’t a miracle solution, but it’s a surprisingly useful, low-cost way to absorb moisture and reduce mild odors. Sometimes the oddest tricks work best.
