By following these safety precautions, you can ensure that the cleaning process is safe and effective. Always refer to the manufacturer's guidelines for specific safety instructions.

Cleaning the Interior

Keeping the interior of a commercial dishwasher clean is essential for its efficient operation. Here are the steps to follow:

Remove Debris and Food Residue

Before cleaning the interior of the dishwasher, it is essential to remove any debris and food residue. This can be done by scraping off any food particles on the walls and bottom of the dishwasher. The debris can be collected in a scrap basket and discarded.

Apply Dishwasher Cleaner Solution

After removing the debris, the next step is to apply a dishwasher cleaner solution. Follow the instructions on the package and allow the cleaner to sit for at least one hour. This will help remove any lime buildup or mineral deposits from the dishwasher's interior.

Scrub the Interior

After the cleaner has been sitting for an hour, use a soft cloth or a light brush to scrub the interior of the dishwasher. Include the door guides and hard-to-reach corners. Scrub the interior thoroughly, paying special attention to areas with heavy buildup.

Rinse the Interior

Once the interior has been scrubbed, rinse it with potable water or a spray nozzle to remove any remaining cleaner and debris. Make sure to rinse thoroughly to prevent any leftover cleaner from contaminating the dishes during the next wash cycle.

By following these steps, the interior of the commercial dishwasher can be kept clean, ensuring its efficient operation and preventing any contamination of the dishes.

Cleaning the Exterior

Keeping the exterior of a commercial dishwasher clean is essential to ensure its longevity and efficient operation. Here are some tips on cleaning a commercial dishwasher's exterior.

Wipe Down the Exterior

The first step in cleaning the exterior of a commercial dishwasher is to wipe it down with a soft, damp cloth. This will remove any dust or dirt that has accumulated on the surface. If there are any stubborn stains or grease marks, a mild detergent can be added to the cloth. Be sure to rinse the cloth thoroughly before wiping down the dishwasher again to avoid leaving any soap residue.

A stainless steel cleaner like Affresh Stainless Steel Cleaner can be used for stainless steel exteriors. Avoid using abrasive cleaning products on the exterior of the dishwasher, as they can scratch the surface.

Clean the Control Panel

A commercial dishwasher's control panel is the machine's nerve center. It is important to keep it clean and free of debris to ensure proper operation. To clean the control panel, use a soft, damp cloth and wipe it down gently. Avoid using abrasive cleaning products or excessive amounts of water, as they can damage the electronics.

If there are any stubborn stains on the control panel, a mild detergent can be added to the cloth. Be sure to rinse the cloth thoroughly before wiping down the control panel again to avoid leaving any soap residue.

Cleaning the Filters

Filters are an essential part of any dishwasher, and they need to be regularly cleaned to prevent clogs and maintain the dishwasher's efficiency. Here are the steps for cleaning the filters:

Remove the Filters

The first step is to remove the filters from the dishwasher. Depending on the model of your dishwasher, the filters may be located at the bottom, back, or side of the machine. Refer to your dishwasher's user manual to locate the filters and remove them carefully.

Soak the Filters

Once you have removed the filters, soak them in a cleaning solution. You can use a commercial dishwasher cleaner or make your own solution by mixing equal parts of water and vinegar. Let the filters soak for at least 30 minutes to loosen any debris or build-up.

Over time, these spray arms can become clogged with food debris, mineral deposits, and other grime, leading to poor cleaning performance. Here's how to clean your dishwasher spray arms to keep your machine running efficiently.

Rinse the Spray Arms

Once you've scrubbed the spray arms, rinse them thoroughly under running water to remove any remaining cleaning solution and debris. Make sure all the spray holes are clear and free of obstructions.

Finally, rinse the drain with hot water to remove any remaining debris or cleaning solution.
