Why placing a roll of toilet paper in the fridge can actually be useful
On TikTok, savvy-savings expert Jonathan Coni is reviving an idea as simple as it is effective: tuck a roll of toilet paper in the refrigerator to soak up moisture and rein in energy use.
At a time when every kilowatt-hour counts, this trick joins the smart habits that help older or poorly insulated fridges run more efficiently.
Another little-known lever: run a hair dryer over the door seals to restore them and curb cold-air leaks.
A way to trim the bill without replacing the appliance—and with a bonus for the planet.
When a toilet paper roll finds its way into the fridge
Placing a simple toilet paper roll in the refrigerator to save energy—the tip, popularized by Jonathan Coni, a day-to-day deals expert—shakes up routines. It’s no longer just useful in the bathroom; it turns into a home-efficiency tool that’s as intriguing as it is appealing.
An unexpected ally against moisture
The idea is straightforward: the paper fibers absorb the moisture inside the chilled compartment, which reduces condensation. In drier air, the compressor tends to cycle on less often, temperatures stay steadier, and energy use can drop. Results vary by how you use the fridge and the model, but the logic of a DIY mini “dehumidifier” holds up.
This slight drying also helps keep unwanted odors in check, since moisture makes odors linger. To avoid saturation and any risk of mold, place the roll in a clean spot, away from splashes, and replace it as soon as it feels damp to the touch.
Give your fridge door seals a new lease on life
Another tip from Jonathan Coni to boost your appliance’s performance: revive the door seals with a hair dryer. Over time, they deform or stiffen and let warm air in. Blowing warm air from a safe distance softens the material and helps the lips of the seal spring back into shape, improving the seal. Work in short bursts with the door open, then close it and press lightly to help it adhere.
• Swap the toilet paper roll every 2 to 3 weeks for best results.
• Regularly check the seal with a sheet of paper: if it slides easily between the door and the fridge, a quick pass with the hair dryer could help.
Cut costs and protect the planet
These simple actions make the most sense on older refrigerators or poorly insulated ones, which are often more demanding in energy. The payoff: some savings and a lighter environmental footprint, without investing in pricey equipment. The goal is to optimize what you already have by managing moisture and the seal—two levers that directly influence cooling cycles and electricity use.
Day to day, a well-placed roll and well-maintained seals can deliver measurable gains, especially in a fridge that’s packed or opened often.
