Los Angeles, California – Open refrigerators from coastal Los Angeles apartments to suburban kitchens in Las Vegas this spring, and you may notice something unexpected tucked beside the produce: a roll of toilet paper.
The unusual household trend has gained traction across California and Nevada as spring temperature swings and regional moisture shifts create condensation inside refrigerators. While Nevada’s desert climate is typically dry, indoor cooling systems and fluctuating temperatures can still lead to moisture buildup. In California, coastal humidity and marine layer patterns can add to the issue.
Supporters say placing a fresh, unscented roll inside the fridge helps absorb excess condensation and reduce lingering food odors. The concept 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 moisture caused by frequent door openings and sharp temperature changes — common during warm afternoons in cities like San Diego, Sacramento and Reno.
Food safety experts caution that the method offers 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 solutions such as baking soda, activated charcoal and routine refrigerator cleaning remain more effective.
For households from the Pacific Coast to the Nevada desert, the toilet paper trick may provide a short-term freshness boost this spring, but consistent cleaning and proper food storage remain the most reliable solution.
