Rack washers: what is it, how it works and how to pick one

Rack washers aren’t just a convenience. They’re a critical line of defense against contamination. Without them, even the most meticulously maintained racks become breeding grounds for grease, oil, and dirt. These contaminants can easily transfer to stored items, leading to quality issues, damaged reputation, or, in worst cases, costly product recalls.

Manual cleaning is time-consuming, and often misses hard-to-reach areas, leaving risks behind. Rack washers, on the other hand, are highly automated systems designed to clean racks of all sizes thoroughly and efficiently, using less water, energy, and labor. But with so many models and configurations available, how do you choose the right one? Here’s what you need to know.

What is a rack washer?

A rack washer is an industrial washing machine specifically designed to wash racks, trays, carts, and similar items used in various industries. Unlike standard washers or manual washing methods, these machines are built to handle the high-volume, heavy-duty washing that most industrial environments require. Rack washers typically use a combination of water, detergents, and mechanical action to ensure a thorough wash for even the most stubborn grime.

The advantages of rack washers

What really makes rack washers stand out? Here are some key advantages:

Efficiency at scale

Rack washers are built for high-volume operations, allowing businesses to wash a large number of items in a single cycle. Instead of washing individual racks or trays manually, you can load them all at once, significantly speeding up the cleaning process. This time-saving feature is crucial in industries where equipment needs to be ready for use as quickly as possible. By handling more items per wash, these machines help teams work more efficiently, reducing downtime and allowing staff to focus on other important tasks.

Thorough washing

Rack washers are designed to tackle the toughest dirt and residue, ensuring that every item gets a complete and thorough wash. The machine’s high-pressure water jets and targeted spraying system reach every corner, even those that are hard to wash by hand. This is essential for industries like healthcare and food services. With a rack washer, you can trust that even the most stubborn grime or contaminants will be fully removed, leaving everything spotless and safe for use.

Cost savings

Even though a rack washer might seem like a big investment, the savings over time more than make up for it. These machines reduce the need for labour-intensive manual washing, freeing up your team for other tasks. Additionally, they are designed to use water and detergent efficiently, cutting down on utility and supply costs. In the long run, the operational savings, coupled with the reduced need for replacement washing equipment, make rack washers a smart financial decision.

Improved hygiene

In industries where hygiene is non-negotiable, rack washers help you maintain the highest standards. These machines are engineered to meet strict health and safety requirements, ensuring that every wash meets your industry’s sanitation protocols. High temperature washing cycles and powerful rinsing systems eliminate harmful bacteria and contaminants, making sure your equipment is ready for immediate use.

User-friendly operation

Rack washers may be powerful, but they are surprisingly easy to operate. MultiWasher, the industrial washing machine developed by Somengil, features intuitive control systems that allow users to start a wash with just a few settings or button presses. Advanced features like programmable cycles and automated drying take the guesswork out of washing, allowing operators to focus on other aspects of the business. The simplicity of these machines means you can get reliable results every time, without needing specialized training or maintenance efforts.

Which companies are rack washers meant for?

If your business relies on reusable equipment that needs to be consistently washed and compliant with hygiene standards, a trolley or rack washer might be exactly what you need. These machines are built to serve a wide range of industries, and for good reason.

• Food and beverage processing: Ideal for removing grease, food residue, and bacteria from trays, carts, and racks, while meeting strict sanitation standards.
• Healthcare and pharmaceuticals: Critical for sterilizing transport equipment and minimizing cross-contamination in sensitive environments.
• Hospitality and catering: Perfect for quickly turning over service carts and kitchen racks between events or meal services.
• Industrial manufacturing: Useful for washing tools, parts, and carriers used in production lines, keeping everything in top condition.
• Logistics and distribution: Ensures that reusable containers and trolleys are washed and ready for safe transport across facilities.

What technologies go into trolley and rack washers?

While operating a rack washer might be as simple as pressing a button, there’s powerful technology working behind the scenes to make that simplicity possible. Today’s top machines, like MultiWasher, are packed with smart features that combine performance with efficiency.

• High-pressure water jets: Strategically positioned to reach all surfaces — even hidden corners — for a complete wash.

How to choose the right rack washer

By focusing on a few key factors, you can make sure you're getting the best machine for your specific needs.

1. Capacity: matching the machine to your workflow

When selecting a rack washer, one of the most important factors to consider is the machine’s capacity. Start by assessing the number of items your business needs to wash daily. A machine with a larger capacity can handle more racks per cycle, which is essential for operations running around the clock or processing high volumes of equipment.

If your facility regularly experiences peak washing times, a high-capacity washer will prevent bottlenecks, allowing you to maintain a smooth workflow. On the other hand, if your cleaning needs are smaller or more sporadic, a medium-sized machine might suit your business better. Always aim to balance capacity with demand to avoid unnecessary operating costs or idle equipment.

2. Washing requirements: consider industry standards and specific needs

Different industries have different washing requirements, and it's vital to choose a rack washer machine that meets the specific standards of your sector. For example, healthcare facilities and food production plants often have stricter sanitation regulations, requiring machines that can disinfect items thoroughly. A rack washer with higher temperatures, stronger water pressure, or built-in disinfectant options might be necessary in these cases. Additionally, consider whether your equipment has unique cleaning challenges – such as delicate components, hard-to-reach areas, or particularly tough grime - that require specialized washing functions.

3. Energy efficiency: balancing performance and operating costs

More than just a buzzword, energy efficiency is a critical factor that directly affects your business’s operational costs. Look for a rack washer that balances powerful cleaning with minimal energy and water consumption. Machines with energy-efficient technologies, like MultiWasher, can significantly reduce your utility bills over time. Features like low-water wash cycles, energy-saving modes, and heat recovery systems are all worth considering. While energy-efficient models may have a higher initial price tag, the savings you’ll gain through reduced electricity and water use can quickly offset that.

4. Ease of use: streamlining daily operations

In any busy industrial environment, having equipment that’s easy to operate can make a big difference in your day-to-day efficiency. When choosing a rack washer, pay attention to how intuitive its controls are. Is it simple enough for your team to use without extensive training? Does it have customizable settings that let you adjust wash cycles for different items, or automated features that reduce the need for manual input? User-friendly machines reduce the chance of operator error and also save time during busy periods. MultiWasher even allows you to program multiple wash cycles, enabling you to tailor each cycle to specific cleaning needs with just the press of a button.

5. Durability and maintenance: investing in longevity

Rack washers are an investment, so it’s essential to choose a model that will stand the test of time. Durability is key in industrial environments where machines are expected to run frequently, sometimes around the clock. Look for rack washers built from high-quality materials like stainless steel, which can withstand the wear and tear of daily use, high temperatures, and constant exposure to water and cleaning chemicals.

Additionally, check what kind of maintenance the machine requires. Models featuring self-cleaning capabilities, combined with built-in diagnostics, can minimize downtime and help maintain the washer in optimal condition for years to come. A machine that’s durable and easy to maintain will not only last longer but also save you money on repairs and replacements. All these are some of the MultiWasher main attributes that are making a difference in all industries.

6. Support: reliable after-sales service matters

Even the best machines will require some level of support or maintenance throughout their lifespan, so it's crucial to choose a rack washer machine backed by strong customer service and technical support. Before making a purchase, check whether the manufacturer or supplier offers ongoing support, such as installation assistance, training for your staff, and regular maintenance services. Knowing that help is readily available when you need it ensures that your operations won’t come to a halt due to technical issues.

How to maximize the lifespan of your rack washer?

Like any industrial equipment, your rack washer is a long-term investment — and with the right care, it will deliver reliable performance for many years. Here’s how to keep it running at its best:

• Clean internal components regularly: Including filters, spray arms, and drainage systems, to prevent buildup and maintain water pressure.
• Use the machine correctly: Stick to recommended detergent types, follow the operating guidelines, and avoid overloading.
• Train your team: Proper usage reduces wear and tear and minimizes the risk of breakdowns caused by user error.
• Schedule preventive maintenance: Periodic checkups by certified technicians can catch small issues before they lead to bigger problems.
• Leverage smart diagnostics: Many modern washers include built-in monitoring that helps track usage and detect inefficiencies.
• Choose durable materials: Stainless steel construction and corrosion-resistant components offer better performance and longevity in tough environments.
