While it may sound like a quirky internet joke at first glance, placing a roll of toilet paper in your fridge actually has practical physical and hygiene benefits.

Effective Odor Neutralization
Toilet paper is made of extremely absorbent cellulose fibers. Refrigerators often have high humidity levels that trap unpleasant odors from cheese, onions, or fish. A dry roll of toilet paper acts like a sponge: it attracts and traps excess moisture and the odor molecules it contains.

Prevents mold growth
By absorbing moisture, the roll reduces the relative humidity inside the fridge. This slows down the growth of spoilage in fragile fruits and vegetables and prevents condensation from forming on the back walls or on food.
An affordable alternative to specialty products
Compared to store-bought activated charcoal or baking soda deodorants, toilet paper is extremely inexpensive, readily available, and chemical-free.

How to use it correctly

Placement: Place a new, unused roll in the back of your refrigerator (where moisture tends to accumulate).

Enhancement (optional): A few drops of vanilla extract or a sprinkle of baking soda on the cardboard core will add freshness.

Replacement: When the roll becomes visibly damp (usually after 2 to 4 weeks), it should be discarded. It should then no longer be used in the bathroom, as it has absorbed bacteria and odors from the refrigerator
