Can rack type dishwashers clean plastic dishes well?

As a supplier of Rack Type Dishwashers, I often get asked about the effectiveness of our machines in cleaning plastic dishes. Plastic dishes are ubiquitous in both commercial and residential settings due to their affordability, durability, and lightweight nature. However, cleaning them thoroughly can be a challenge, especially when dealing with stubborn stains and food residues. In this blog post, I will explore whether rack type dishwashers can clean plastic dishes well and provide some insights into how to achieve optimal cleaning results.

Understanding Rack Type Dishwashers

Rack type dishwashers are designed for high - volume dishwashing operations, commonly found in restaurants, cafeterias, and other commercial kitchens. These machines use a rack system to hold the dishes during the cleaning process. The racks are loaded with dirty dishes and then moved through a series of wash, rinse, and sanitizing cycles. There are different types of rack type dishwashers, such as Basket - Conveyor Dishwashers and Pass Through Dishwashers, each with its own unique features and benefits.

The key advantage of rack type dishwashers is their ability to handle a large number of dishes in a relatively short period. They are equipped with powerful spray arms that deliver high - pressure water jets to remove dirt and debris from the dishes. Additionally, they use specialized detergents and sanitizers to ensure that the dishes are not only clean but also free from harmful bacteria.

Challenges of Cleaning Plastic Dishes

Plastic dishes present some unique challenges when it comes to cleaning. One of the main issues is that plastic is a porous material, which means that it can absorb food stains and odors more easily than other materials like glass or ceramic. Over time, these stains can become deeply embedded in the plastic, making them difficult to remove.

Another challenge is that plastic can be sensitive to high temperatures and harsh chemicals. Exposing plastic dishes to extremely hot water or strong detergents can cause them to warp, melt, or become discolored. This is a concern, especially in commercial dishwashing operations where high - temperature sanitizing cycles are often used.

Can Rack Type Dishwashers Clean Plastic Dishes Well?

The short answer is yes, rack type dishwashers can clean plastic dishes well, but it depends on several factors.

Water Temperature

Most rack type dishwashers have adjustable water temperature settings. For plastic dishes, it is recommended to use a lower water temperature to prevent warping and melting. Generally, a water temperature between 120°F (49°C) and 140°F (60°C) is suitable for cleaning plastic dishes. This temperature range is high enough to remove dirt and grease but low enough to protect the plastic.

Detergent Selection

Choosing the right detergent is crucial for cleaning plastic dishes. Harsh detergents with strong chemicals can damage the plastic. Instead, opt for mild, pH - balanced detergents that are specifically formulated for use with plastic. These detergents are gentle on the plastic while still being effective at removing stains and food residues.

Loading Technique

Proper loading of the plastic dishes into the rack is also important. Make sure that the dishes are not overcrowded, as this can prevent the water jets from reaching all surfaces of the dishes. Arrange the dishes in a way that allows for maximum exposure to the water and detergent. For example, place bowls and plates on their sides rather than stacking them flat.

Cycle Selection

Some rack type dishwashers offer different cycle options. For plastic dishes, a shorter, gentler cycle may be more appropriate. This can help to reduce the exposure of the plastic to high - pressure water and harsh chemicals, minimizing the risk of damage.

Tips for Optimal Cleaning of Plastic Dishes in Rack Type Dishwashers

Pre - rinse the Dishes

Before loading the plastic dishes into the rack type dishwasher, give them a quick pre - rinse under running water. This can help to remove large pieces of food debris, making the cleaning process more effective.

Use a Rinse Aid

A rinse aid can help to improve the drying process and prevent water spots from forming on the plastic dishes. It also helps to reduce the surface tension of the water, allowing it to drain more easily from the dishes.

Inspect the Dishes Regularly

After each cycle, inspect the plastic dishes for any signs of damage or remaining stains. If you notice any issues, adjust the water temperature, detergent, or loading technique accordingly.

Conclusion

In conclusion, rack type dishwashers can be an effective solution for cleaning plastic dishes, provided that the right conditions are met. By carefully controlling the water temperature, selecting the appropriate detergent, using proper loading techniques, and choosing the right cycle, you can achieve excellent cleaning results without damaging the plastic.
