Essential Cleaning Tips for Laboratory Refrigerators



Like any piece of equipment, your laboratory refrigerator needs routine care. Regular maintenance and proper cleaning are important for peak performance. In this article, you’ll learn how to use simple cleaning tips to care for your laboratory refrigerator.


Cleaning Procedures

Regular cleaning is vital to keeping your laboratory hygienic and clean. It can even enhance the efficiency of your equipment. Follow these steps for simple and effective cleaning of your laboratory refrigerator:


Power Off and Empty

Turn off your refrigerator and remove all its contents. Transfer temperature-sensitive items to an alternative refrigerator to maintain their integrity.


Defrost (If Applicable)

If your refrigerator or freezer has a manual defrost feature, allow the ice to melt naturally. Avoid using sharp objects or excessive force to speed up the defrosting process, as this can damage the unit’s interior.


Clean the Interior

Use a mild detergent or a solution of warm water and vinegar to clean the interior surfaces. Pay special attention to shelves, walls, and door gaskets. Avoid using harsh chemicals or abrasive materials that may damage the refrigerator or leave contaminating fumes.


Gasket Maintenance

Inspect the door gaskets for any signs of damage or wear. Clean them using a soft cloth or sponge dipped in mild soapy water. Ensure they are free from debris and properly seal shut when closed. Gaskets can be easily damaged or weakened, so this is a key step to making sure your refrigerator is properly retaining cold air.


Clean the Coils

Often overlooked are the refrigerator condenser coils. These important coils can typically be found on the outside of the unit. Dust off or vacuum out dust and debris from the condenser and coils to keep air flowing smoothly and extend the refrigerator lifespan.1 The condenser fins and coils should be cleaned at least twice a year or more often if dust builds up quickly in your space.  


Exterior Cleaning

Wipe the remaining exterior surfaces of the refrigerator with a damp cloth or sponge. Again, avoid using abrasive materials or harsh chemicals that may harm the finish.


Reassemble and Power On

Once the interior and exterior are clean and dry, reassemble the shelves, racks, and containers. Power on the refrigerator and allow it to reach the desired temperature before returning the stored items to the shelves.


Organize and Label Contents

Organization is key. Store your refrigerator contents in appropriate containers, using racks, shelves, and bins as necessary. Properly label all samples and securely close all containers to prevent leakage or spills.


Wrapping Up

Maintaining a clean and efficient laboratory refrigerator will keep you, your materials, and your laboratory safe. By following these simple cleaning procedures, you can boost your refrigerator’s performance and extend its lifespan. Your refrigerator, environment, and coworkers will be safer and happier because of it.
