Minneapolis, Minnesota – Open refrigerators from Minneapolis condos to Milwaukee bungalows this spring, and you may spot something unexpected sitting beside the leftovers: a roll of toilet paper.
The unusual household trend has gained attention across Minnesota and Wisconsin as spring thaws bring fluctuating temperatures and rising humidity. Supporters say placing a fresh, unscented roll inside the fridge helps absorb excess moisture and reduce stubborn food odors, especially in older homes common in St. Paul, Madison and Green Bay.
The idea is rooted in basic material science. Toilet paper is made from cellulose fibers designed to absorb liquid efficiently. Inside a refrigerator, those fibers can draw in condensation caused by frequent door openings and sharp temperature swings — common during Upper Midwest spring days that start near freezing and climb into milder afternoon readings.
Food safety experts caution that the method provides only temporary benefits. Once the roll becomes damp, it can trap bacteria rather than prevent it. Specialists recommend replacing it regularly and keeping it away from uncovered food. Scented or dyed varieties should not be stored near groceries.
Long-term odor control methods such as baking soda, activated charcoal and routine refrigerator cleaning remain more effective, particularly during damp stretches near Lake Superior and across central Wisconsin.
For households from the Twin Cities to the shores of Lake Michigan, the toilet paper trick may offer a short-term freshness boost this spring, but consistent cleaning and proper food storage remain the most reliable solution.
