How to Maintain Your Refrigerator Gaskets

Did you know that rubber comes from trees? And if you use synthetic rubber, did you know it comes from petroleum?

Many manufacturing companies use rubber to create seals for their commercial refrigeration units. However, once it’s in your store, it’s your job to maintain the rubber seals, which sounds easier than it is.

The Most Common Problem for Gaskets

Whether your refrigerator uses natural or synthetic rubber, the most common problem for door seals is drying out.


Natural rubber is a plant product, and synthetic is oil-based, so it’s understandable how they dry out over time without proper maintenance and lubrication–the air saps all moisture out.

Easy Solutions for Weak Seals

Even though rubber seals dry out over time, you can extend their life with three simple maintenance tips that require minimal effort but can save you a lot of money.

#1: Wipe Down the Gaskets

The best way to ensure your refrigerator door seals last a long time is to clean the dirt and debris regularly. The moment any liquids get on the refrigerator gasket, you want to wipe them down and clean them with a cleaning solution, like warm water and soap or baking soda and water.

#2: Clean the Refrigerator’s Exterior

Regularly cleaning the outside helps prevent gunk buildup on the gaskets.

You have hundreds and thousands of customers per day and year using your refrigerator doors. The dirt and skin oil on their hands slowly collects over time.

As more people use the door, the more grime spreads to the gaskets, which prevents them from sealing properly.

#3: Apply Petroleum Jelly

Even though you clean your units, the refrigerator door gasket dries out. Why? Because the surrounding cold air and temperatures sap the moisture out.

Use petroleum jelly on a paper towel to moisten and reinvigorate your gaskets. You will lengthen their lifespan with just a thin layer and renew the airtight seal.
