Ultrasonic cleaners have become a popular choice for cleaning jewelry, eyeglasses, and other small items in recent years. The ultrasonic system create tiny bubbles that scrub the surface of the item being cleaned.
This process is said to be more effective than traditional methods like hand washing or using soap and water. But does ultrasonic cleaning damage metal? Let’s take a closer look.
Can Ultrasonic Cleaner Damage Metal?
The short answer is no, ultrasonic cleaners will not damage the metal. In fact, ultrasonic cleaning is often used to clean delicate metals like jewelry and eyeglasses because it is gentle and effective.
So, Is Ultrasonic Cleaning Safe for Metal?
Yes, ultrasonic cleaning is safe for use on metal surfaces. It’s an excellent way to clean metals because it doesn’t require the use of harsh chemicals or abrasive scrubbing.
That said, there are some instances in which ultrasonic cleaning can damage the metal. For example, if an object is left in an ultrasonic cleaning bath for too long, the cavitation process can cause pitting or other types of surface damage.
Additionally, some metals with a low melting point (e.g. aluminum components) may be damaged by the heat generated by the cavitation process.
As a result, it’s important to consult the manufacturer’s instructions when using an ultrasonic cleaning system and to exercise caution when cleaning delicate parts.
Let’s go through the basics of ultrasonic cleaning and how it can be used to clean metal without damaging it.
How do Ultrasonic Cleaners work?
Ultrasonic cleaners use high-frequency sound waves to create cavitation bubbles in the cleaning solution. The collapse of these microscopic bubbles produces tiny jets of liquid that remove dirt and grime from the surface of an object.
Ultrasonic cleaners can be used with water or solvents and are effective at cleaning a wide variety of materials, including metals.
How Ultrasonic Waves are Created?
Ultrasonic waves are created by a transducer that converts electrical energy into sound waves. The waves are then sent into a cleaning tank filled with cleaning solutions and cleaning products.
The waves create a cleaning action that helps remove contaminants from the surface of the products you are cleaning. The frequency of the waves is usually between 20-40 kHz.
What is the Best Frequency for Ultrasonic Cleaning?
The ultrasonic cleaning action is created by cavitation. Ultrasonic cavitation is the formation and implosion of bubbles in a liquid, and it only occurs when the liquid is exposed to ultrasound.
The ultrasonic frequencies cause the formation of microscopic bubbles, which quickly grow and then collapse. It is this collapse that creates the cleaning action.
The frequency of the ultrasonic waves determines the size of the bubbles that are created. High frequencies create smaller bubbles, while low frequencies create larger bubbles.
When the bubbles implode, they create a jet of liquid that can remove contaminants from surfaces for the objects being cleaned.
So, how do you choose the best frequency for ultrasonic cleaning? As we mentioned before, it depends on the type of metal you are trying to clean.
If you are cleaning a delicate or highly polished surfaces, such as jewelry, you will want to use a higher frequency so that the bubbles are smaller and will not damage the surface of the item.
If you are cleaning a gross contaminant, such as oil or grease, you will want to use a lower frequency so that the bubbles are larger and will be able to remove the contaminant more effectively.
Some ultrasonic cleaning equipment is designed to operate at specific frequencies, such as 25, 37, 40, 45, or 80 kHz.
If you are unsure of what frequency to use, you can always start with a lower frequency and increase the frequency if necessary.
If you find that the cleaning action is not as effective as you would like, try increasing the frequency until you find the sweet spot.
What Metals Can Go in an Ultrasonic Cleaner?
You might be surprised to learn that there are few if any metals that cannot go in an ultrasonic cleaner.
This is because ultrasonic cleaners use high-frequency sound waves to create cavitation bubbles. These bubbles gently scrub away dirt and grime, without damaging the metal surface.
In fact, ultrasonic cleaning can actually prolong the life of your metal parts by keeping them clean and free of corrosion-causing buildup.
So, what metals can go in an ultrasonic cleaner? Almost all of them! Ultrasonic cleaners can safely clean aluminum, brass, magnesium, stainless steel, titanium, gold, silver, and more.
The only exceptions are organic materials like pearls and amber etc., which can be damaged by the ultrasonic cleaning process.
So, if you need to clean any metal object, an ultrasonic cleaner is a safe and effective option. Just be sure to use a compatible detergent to avoid damaging your metals.
With ultrasonic cleaning, you can keep your metal objects looking like new for years to come.
7 Ultrasonic Cleaning Tips for Safe Metal Cleaning
-
Choose the right cleaner.
Not all cleaners are created equal. Do your research to find a cleaner that is specifically designed for ultrasonic cleaning and that will work well with the type of item you’re trying to clean.
-
Pre-treat stubborn stains.
If you’re trying to remove a tough stain, pre-treating the item with a stain remover can help loosen the stain and make it easier to remove during the ultrasonic cleaning process.
-
Fill the tank with enough liquid.
For ultrasonic waves to clean effectively, the tank needs to be filled with enough liquid so that the waves can move freely.
-
Follow the manufacturer’s instructions.
Every ultrasonic cleaner is different, so be sure to read the manufacturer’s instructions carefully before using yours. This will ensure that you’re using your cleaner correctly and getting the best possible results.
-
Don’t overdo it.
Ultrasonic energy is powerful, so you don’t need to use them for an extended period of time in order to clean your item effectively.
In fact, using them for too long can actually damage your item, so be sure to follow the manufacturer’s recommended cleaning time.
-
Rinse your item after cleaning.
Once you’ve finished ultrasonically cleaning your item, be sure to rinse it off with clean water to remove any residual cleaners or dirt that may be left behind.
-
Dry your item thoroughly.
The last step in ultrasonic cleaning is drying your item completely. Post-cleaning doing this will help prevent rusting or other damage that could occur if your item is left wet after cleaning.
Use these tips the next time you need to give something a good cleaning and want to try using ultrasound waves instead of traditional methods like scrubbing or soaking overnight!
Conclusion
Ultrasonic cleaners are safe and effective ways to clean metal surfaces when used correctly. However, there are some instances in which use of ultrasonic cleaners can cause surface damage to metal objects.
To avoid damaging your metal parts, make sure to follow the manufacturer’s instructions for setting the power level and only leave your object in the cleaner for the recommended amount of time.
By following these simple guidelines, you can help ensure that your metal objects will stay looking like new for years to come.
