Putting a roll of toilet paper in the fridge is a popular internet life-hack used primarily as a budget-friendly way to control odors and excess moisture.
The Science Behind It
-
Moisture Control: Refrigerators are prone to humidity and condensation from food, drinks, and frequent door openings. Because toilet paper is engineered to be highly absorbent, the loose cellulose fibers act like a sponge, soaking up stray moisture in the air.
-
Odor Absorption: By trapping ambient moisture, the paper also catches some of the airborne microscopic odor particles floating around from strong-smelling foods (like leftover cheese, onions, or garlic).
How to Do It (If You Want to Try It)
-
Go unwrapped: Remove any plastic packaging so the paper can actually “breathe” and interact with the air.
-
Placement: Set it on a shelf away from dripping liquids, produce, or condensation heavy-zones so it doesn’t get soggy too fast.
-
Swap it out: Because it absorbs moisture quickly, you have to replace the roll every 3 to 4 weeks (otherwise it can become a breeding ground for dampness). Bonus: You can still use the “spent” dry parts of the roll in the bathroom later so nothing goes to waste!
Does It Actually Work?
It does offer mild passive odor absorption, much like an open box of baking soda. However, critics point out that it’s not a silver bullet: baking soda chemically neutralizes odors rather than just trapping them, and activated charcoal or proper deep-cleaning are far more effective for dealing with stubborn fridge smells.
Would you give this trick a try, or do you prefer the classic baking soda box?
