Philadelphia, Pennsylvania – Open refrigerators from Center City apartments to Pittsburgh townhomes this spring, and you might find something unusual tucked beside the leftovers: a roll of toilet paper.
The household hack has gained attention across Pennsylvania as spring humidity increases and temperatures fluctuate. Supporters say placing a fresh, unscented roll inside the fridge helps absorb excess moisture and reduce stubborn food odors, particularly in older brick homes common in Philadelphia, Harrisburg and Scranton.
The idea relies on basic material science. Toilet paper is made of cellulose fibers engineered to absorb liquid efficiently. Inside a refrigerator, those fibers can draw in condensation caused by frequent door openings and sharp temperature swings — common during Pennsylvania’s cool mornings and warmer spring afternoons.
Food safety specialists caution that the method offers only temporary results. Once the roll becomes damp, it can trap bacteria rather than prevent it. Experts recommend replacing it frequently and keeping it away from uncovered food. Scented or dyed varieties should not be used near groceries.
Long-term odor control methods such as baking soda, activated charcoal and routine refrigerator cleaning remain more effective, especially during damp stretches in eastern and western Pennsylvania.
For households from Philadelphia to Pittsburgh, the toilet paper trick may offer a short-term freshness boost this spring, but consistent cleaning and proper food storage remain the most dependable strategy.
