3 Big Cost Savings Benefits of Using Ultrasonic Cleaners vs. Spray Washers


If there’s one thing that business and facilities owners want when they’re considering a cleaning solution, it should be cost-effective.

Ultrasonic cleaners provide an excellent cleaning alternative to other traditional methods of cleaning, like spray washers. Ultrasonic cleaners can clean anything from delicate medical parts to machine parts, and everything in between.

But there are also other ways that business owners can benefit from using ultrasonic cleaners as opposed to spray washers, in relation to the cost:


  1. Save on materials
    Spray washers rely on large amounts of chemicals to clean stains and require operators to use protective equipment. These concerns are non-existent with ultrasonic cleaners. Cleaning with high-frequency pressure waves does not require chemical action to loosen stains. While it requires a mild detergent to help loosen the most stubborn stains, it is otherwise inexpensive when compared to the number of chemicals used in spray washers.
  2. Save on labor costs
    The ultrasonic waves generated by these cleaners do not need to be directly aimed at surfaces to be cleaned. The microscopic bubbles travel in every nook and cranny of the tools and parts being cleaned, assuring thorough cleaning. With ultrasonic cleaning, the parts become cleaner with less effort.
  3. Save on maintenance
    Spray washers may require lots of energy to operate. It has moving parts as well that require expensive maintenance — if they cannot be maintained regularly, they would eventually lose their usefulness. Customized ultrasonic cleaners do not require much maintenance — they don’t come with moving parts — all you have is a transducer and a bath of liquid. With very little maintenance, ultrasonic cleaning systems are guaranteed to last a lifetime

Cleaning Brass and Stainless Steel Using Ultrasonic Parts Cleaners

Ultrasonic parts cleaners use transducers and ultrasonic frequency generators to produce microscopic bubbles in water (or a mild cleaning solution). These tiny bubbles act as “scrubbers” that are highly effective in lifting away dirt and impurities from the parts being cleaned.

Ultrasonic parts cleaners are an excellent alternative to the traditional cleaning methods that use intense scrubbing and harsh cleaning chemicals that can leave deposits or cause damage to these parts.

Tools that are made of brass and stainless steel can also be cleaned using ultrasonic parts cleaners. These are considered “robust” parts. Ultrasonic cleaners operating at the lower ultrasonic frequency ranges are the most effective for cleaning such parts. Ultrasonic generators for 26 kHz or 38 kHz create large, energetic bubbles that form and collapse in time with the cleaning frequency. When these bubbles collapse at the surface of the brass or stainless steel, they release bursts of energy that dislodge dirt and impurities, while never causing damage to the solid metal surface.

For parts covered in heavy dirt like oil and grease, the effectiveness of ultrasonic cleaners can be improved by adding only a mild detergent to the water bath and by slightly heating the cleaning solution. The heat will help melt the oil and grease away from the surface while the detergent dissolves them. The ultrasonic bubbles penetrate wherever there is cleaning solution, leaving the brass and stainless steel parts thoroughly cleaned. Ultrasonic cleaners also make cleaning these parts quick and efficient as well.

Should De-Ionized Water Be Used with an Ultrasonic Cleaning System?

De-ionized (DI) water is plain water that lacks ions or particles because of the purification process. It is used to remove contaminants like metals and salts (ions).

Should DI water be used with an ultrasonic cleaning system? The answer is yes, depending on the parts being cleaned or the degree of their contamination. When DI water is used in the ultrasonic cleaning system, it can improve the cleaning performance. Such cleaning performance is especially important for parts that cannot tolerate detergents, solvents or other cleaning solution.

Ultrasonic cleaning systems can also use plain water – a mild detergent can be added to enhance the cleaning process. However, delicate tools and parts could not tolerate these detergents, that’s why cleaning them with DI water is often recommended. For parts contaminated with heavy, stubborn dirt and grease, a mild detergent or cleaning solvent (that do not cause damage to the parts themselves) can be added to the DI water for more effective and quick cleaning.

When an ultrasonic cleaning system has removed dirt from the parts to be cleaned, the cleaning solution is drained away but they still must undergo thorough rinsing. Plain water has dissolved minerals the parts and other impurities so that rinsing can leave a deposit. When the parts are dried, spots or films left over from the evaporated plain water can remain in these parts – even the tiniest spot or impurity left over can lead to the malfunction of these parts. That’s why the use of DI water is often recommended for rinsing them since it contains no impurities, leaving these parts spotless and clean.

Why Ultrasonic Cleaning Systems Are Used by Aerospace Manufacturers

Aerospace industry manufacturers need to provide high-precision parts and also maintain and repair parts in production that are used in complex engines and machinery. Production parts and parts from maintenance and repair operations are usually contaminated by grease, dirt, soot, and lubricants as a result of the normal operation.

These parts and tools are traditionally cleaned by either manually washing or scrubbing, or by using harsh solvents. But there’s a better alternative to the traditional cleaning methods – the use of ultrasonic cleaning systems, which saves both time and money along with providing an environmentally friendly process that cleans parts fast and efficiently.

Ultrasonic cleaning systems are made up of an ultrasonic generator, transducer and a cleaning tank. The ultrasonic generator is the “heart” of an ultrasonic cleaning system. The Ultrasonic transducers are installed inside the cleaning tank and convert electric signals from the generator into sound waves in the cleaning solution of the tank. These sound waves create microscopic bubbles that do the cleaning and scrubbing action, lifting away contaminants from the surfaces of the items (such as tools) in the cleaning solution. It leaves the items completely cleaned with no particles left over.

More aerospace manufacturers have transitioned to using ultrasonic cleaning systems from old traditional cleaning methods, for a number of reasons:

  • The cleaning of parts is more effective, efficient and thorough – the microscopic cleaning bubbles have the ability to penetrate and clean even in crevices, holes, and other more complicated and harder-to-reach areas of the tools being cleaned.
  • The cleaning fluid may consist of plain water or only a mild cleaning solution. No harsh and toxic cleaning chemicals needed.
  • It is faster.
  • It doesn’t require manual or mechanical scrubbing.
  • It is cost-effective.
  • It is safer to use compared to using harsh chemicals.
  • The frequencies of the signal can be adjusted to allow appropriate cleaning of robust or delicate tools and items.

Time Vs. Money: How an Ultrasonic Cleaning System Saves Both

Ultrasonic cleaning systems can clean parts and components quickly and thoroughly and provide a superior option compared to traditional methods that use harsh chemicals and mechanical brushing. Plus, these systems help reduce cleaning costs considerably, they also save time and increase the efficiency of many production lines or manufacturing processes.

Ultrasonic cleaning process works by placing the items to be cleaned in a cleaning liquid of a cleaning tank. The sound waves generate cavitation bubbles in the cleaning liquid. These microscopic bubbles dislodge contaminants from the surfaces of the items being cleaned.

Ultrasonic cleaning saves time because the items do not need to be soaked in the cleaning liquid in order to soften the dirt. Subsequent manual scrubbing with pressure sprays is also no longer needed. In ultrasonic cleaning, the bubbles do the cleaning and scrubbing action, and they could clean even the more complicated parts, shapes, holes, and crevices of the items, resulting in quick but thorough cleaning.

The cost savings come from various sources. Because of the high performance of the ultrasonic systems, the need for water and power are reduced and the use of harsh chemicals is eliminated. Depending on the cleaning chemicals previously used, various chemical handling equipment and processing may no longer be needed.

High performance ultrasonic cleaning systems save on power usage since a typical system uses up to 1200 Watts, lower than the power used by conventional cleaning systems. Water use is also reduced because only one tank is needed for cleaning. These reductions translate into bigger savings.

How to an Ultrasonic Generator Works

The ultrasonic generator is the heart of an ultrasonic cleaning system. It generates the high-frequency signal, which the ultrasonic transducers convert to sound waves of the cleaning solution within a cleaning tank. In addition to generating the signal, the ultrasonic generator controls the frequency and the power levels to produce several or a range of frequencies as part of an integrated, turnkey solution or independently to power separate transducers.

As the sound waves go through the cleaning liquid, the cavitation bubbles start to emerge in the low-pressure troughs of the waves, then collapse in high-pressure peaks. This action of the microscopic bubbles leads to a powerful scrubbing action that helps dislodge the dirt and particles off the surfaces of parts (in the cleaning liquid of the cleaning tank). The bubbles can even clean hard-to-reach places like holes and crevices, leaving the item thoroughly cleaned. Ultrasonic cleaning systems are generally considered superior to other traditional methods that use chemicals or mechanical scrubbing.

Apart from producing the high-quality signal, Kaijo’s ultrasonic generators provide the frequency needed to optimize cleaning performance for the specific cleaning application. Setting the right frequency is the key factor for an effective cleaning:

  • Low frequency (26 kHz to 38 kHz range) – This frequency produces large, energetic cavitation bubbles, making them suitable for cleaning machined parts, glass, and wires.
  • Mid-range frequency (78 kHz to 160 kHz) – The bubbles become smaller and the cleaning action is gentler. Suitable for cleaning hard disk drives, solar panels, and ceramic parts.
  • High frequency (450 kHz to 950 kHz) – The bubbles become even smaller and the cleaning action is at its most delicate. Suitable for cleaning semiconductors, LED’s and fragile medical components.

If an Ultrasonic generator is used with a single process to always clean the same parts, selecting a single-frequency model is a good choice. For general-purpose usage, where the ultrasonic cleaning system may be used in a wide variety of cleaning applications, a generator that can produce a range of frequencies is the best option.
