Cleaning and servicing your air curtain refrigerator is the easiest way to ensure that it serves your business for a longer period of time and does not wear out quickly.
Moreover, an air-curtain refrigerator that is regularly cleaned and serviced is better for food safety and energy efficiency: regular cleaning not only prevents bacteria buildup but also boosts the refrigerator's ability to maintain safe temperatures with minimal energy use.
But how often should you clean your open-curtain refrigerator? An air-curtain refrigerator must be cleaned at least every day, with a deep cleaning once a month, a technical check and cleaning about once in three months, and a professional servicing once a year.
1. Daily Cleaning (Daily)
An air-curtain refrigerator needs a limited amount of cleaning and maintenance every day. Daily cleaning helps keep the merchandiser sanitary, presentable, and working efficiently. Follow these six steps:
1. Turn Off Power
- Always switch off or unplug the refrigerator before cleaning
- Disconnecting from the power source avoids electrical hazards.
2. Remove Products
- Take out all food or beverage items
- Remember to place them in another cooler or storage area to keep them at safe temperatures.
3. Wipe Interior Surfaces
- Use a clean cloth or sponge with mild detergent and warm water.
- Wipe down shelves, liners, and interior walls to remove spills, crumbs, or sticky residue.
- Rinse with a damp cloth and dry with a towel to avoid water spots or streaks.
4. Clean Exterior Surfaces
- Wipe down glass panels, display surfaces, and stainless steel areas.
- Use glass cleaner on the viewing panels to keep them clear for customers.
5. Check and Clear Air Curtain Area
- Make sure the air vents at the front opening are free of debris, dust, or packaging that could block airflow.
- Gently vacuum or wipe the intake and discharge vents if needed.
6. Inspect and Reorganize Products
- Before restocking, check expiration dates and product condition.
- Organize items so airflow remains unobstructed (don’t block the vents with tall packaging).
The most important step when it comes to daily cleaning is to wipe down the interior and exterior surfaces of the air-curtain refrigerator.
Wilprep’s 3 Sided Glass Display Refrigerator makes your daily cleaning easier: it is built with robust stainless steel, which is dark in color, and the glass is double-pane, which means maximum results with minimum cleaning.
Why Daily Cleaning Matters
The objective of cleaning an air curtain refrigerator every day is not only to ensure that it is working properly, but also to keep it presentable, well-organized, and attractive to potential customers.
Doing these steps daily helps keep the merchandiser sanitary, presentable, and working efficiently.
2. Weekly Deep Cleaning
Air-curtain merchandisers also need to be cleaned weekly. The objective of weekly cleaning is to prevent buildup or tackle any tough or hidden problems that cannot be identified or handled during daily cleaning.
Cleaning an air curtain merchandiser is a little more intense and demands more attention. Follow these steps carefully:
1. Begin with the Deep Clean Shelves and Trays
- Remove shelves, trays, and product dividers.
- Wash them with warm, soapy water, rinse thoroughly, and let them dry before reinstalling.
2. Vacuum Air Curtain Vents
- Use a soft brush or vacuum attachment to remove dust from the air intake and discharge vents.
- This keeps airflow strong and prevents temperature fluctuations.
3. Inspect Door Gaskets/Seals (if applicable)
- Check rubber seals around doors or sliding covers for cracks, wear, or food buildup.
- Wipe seals with mild detergent to keep them flexible and tight.
4. Check for Obstructions Inside the Unit
- Make sure tall or bulky products aren’t blocking airflow paths.
- Reorganize items to maintain proper cooling distribution.
The most important steps when it comes to monthly cleaning are cleaning the shelves, inspecting the door gaskets, and checking for obstructions.
When you have a large capacity like the Black Vertical Air Curtain Merchandiser, which stands at 76 inches and has four large 66 lb capacity trays, it is hard to spot everything during daily cleaning.
Luckily, this specific unit also has a black stainless steel frame, and the glass is also double-pane. It is easier to clean than most.
Monthly Cleaning and Maintenance
Monthly cleaning mainly targets the essential core technical features of the air-curtain merchandiser (condenser coils, drain lines, thermometers, etc), and is therefore essential for long-term reliability and efficiency.
Follow these steps to clean your air-curtain refrigerator every month:
1. Clean Condenser Coils
- Dust and dirt clog coils, forcing the compressor to work harder.
- Brush gently or use a vacuum to clear debris. (Always disconnect power first.)
2. Flush and Clean Drain Lines
- Locate the drain pan and drain lines under the unit.
- Clear any blockages and clean with a mixture of warm water and mild detergent to prevent foul odors or leaks.
3. Check Thermometers and Temperature Settings
- Verify the unit is holding the correct temperature range (usually 36–40°F for beverages/dairy, depending on local code).
- Adjust the temperatures if necessary.
4. Inspect Fans and Motors
- Listen for unusual noises.
- Make sure fans spin freely without dust buildup.
When it comes to monthly cleaning, all of the steps above are equally important: it is not recommended that you leave any one out. Checking temperature settings is definitely important, and it is a lot easier to do when you have digital controls for adjustments.
Professional Servicing (Quarterly/Half-Yearly)
It is recommended to have an air curtain refrigerator cleaned and serviced by a professional maintenance service every 3-6 months.
- Refrigerant level checks.
- Full mechanical inspection (compressor, evaporator, electrical connections).
- Deep cleaning service of coils, fans, and air ducts.
The larger your air curtain refrigerator, the more often you need professional servicing. This definitely should be one of the most important factors you consider when you decide what size open-air refrigerator you need for your business.
Also, high-quality units often require less professional maintenance. With a good unit like this Black 3-Sided Glass Display Refrigerator, you might need professional servicing just twice a year.
- It is built with durable stainless steel, the glass is double pane, and it comes with a quality compressor and a finned copper tube condenser for consistent performance.
- The back panel is also perforated to boost airflow to keep your items evenly chilled

Air curtain refrigerators need slightly more frequent attention (especially airflow checks and vent cleaning) because their open design makes them more vulnerable to dust, debris, and temperature fluctuations.
Final Thoughts on Cleaning Your Air-Curtain Refrigerator
Daily wipe-downs prevent dirt and spills from building up, weekly cleaning keeps airflow unobstructed, and thorough monthly or quarterly deep cleans ensure your unit runs at peak efficiency.
By sticking to a regular cleaning routine, you’ll extend the lifespan of your refrigerator, maintain proper food safety standards, and ultimately boost your bottom line. A little consistency in care goes a long way in keeping your air curtain refrigerator working like new.
