No, you should not put plastic in an ultrasonic cleaner. Ultrasonic cleaning is not suitable for low-density, flexible, and thermosetting plastics like LDPE, as they can crack or be damaged by the high-frequency sound waves used in the cleaning process.
These plastics actually absorb some of the ultrasonic power, reducing the effectiveness of the cleaning action. It is best to use ultrasonic cleaning for parts with hard surfaces, such as metal, while being cautious with softer surfaces.
Understanding Ultrasonic Cleaning
Ultrasonic cleaning can be effective for certain types of plastic, but not all. Low-density, flexible, and thermosetting plastics like LDPE are not suitable for ultrasonic cleaning as they can crack and get damaged. It’s important to consider the type of plastic before deciding to use an ultrasonic cleaner.
What Is An Ultrasonic Cleaner?
An ultrasonic cleaner is a device commonly used for cleaning various objects and materials. It uses ultrasonic waves to generate tiny, high-frequency vibrations in a liquid cleaning solution. These vibrations create microscopic bubbles that collapse, generating a cleaning action known as cavitation.
This powerful cleaning process is effective in removing dirt, debris, grease, and contaminants from the surface of objects. Ultrasonic cleaners can be used for a wide range of cleaning purposes, including jewelry, eyeglasses, dental instruments, industrial parts, and more.
How Does An Ultrasonic Cleaner Work?
- Ultrasonic cleaners operate by generating high-frequency sound waves, typically between 20-40 kHz.
- These sound waves create microscopic bubbles in the liquid cleaning solution.
- As the bubbles collapse, they release energy in the form of heat, pressure, and powerful cleaning action.
- This process, known as cavitation, effectively cleans and removes contaminants from the submerged objects.
- The cleaning solution used in an ultrasonic cleaner plays a crucial role in the overall effectiveness of the cleaning process.
Benefits Of Using An Ultrasonic Cleaner:
- Efficient cleaning: Ultrasonic cleaners can remove dirt, grease, and contaminants from surfaces that are difficult to reach or clean manually.
- Time-saving: The cavitation process in ultrasonic cleaners enables fast and efficient cleaning, reducing the time and effort required compared to traditional cleaning methods.
- Gentle on delicate items: Ultrasonic cleaning is gentle and non-abrasive, making it suitable for delicate items such as jewelry, watches, and eyeglasses.
- Versatile cleaning applications: Ultrasonic cleaners can be used for a variety of objects and materials, including jewelry, dental instruments, electronic components, automotive parts, and more.
- Environmentally friendly: Ultrasonic cleaning typically requires minimal or no use of harsh chemicals, making it an eco-friendly cleaning method.
- Consistent cleaning results: The controlled and precise cleaning action of ultrasonic cleaners ensures consistent results, making them ideal for industries where cleanliness is critical, such as medical and pharmaceutical fields.
Ultrasonic cleaners are versatile and efficient devices that utilize high-frequency sound waves to generate cavitation for effective cleaning. They offer numerous benefits, making them a preferred choice for various cleaning applications.

Factors To Consider For Cleaning Plastics
Ultrasonic cleaners can be used to clean certain types of plastics, but it’s important to consider the material’s density and flexibility. Low-density, flexible, and thermosetting plastics like LDPE are not suitable for ultrasonic cleaning as they may crack or suffer damage from the high-frequency sound waves.
It’s best to avoid using ultrasonic cleaners on these types of plastics to prevent any potential problems.
Properties Of Different Types Of Plastics:
- Plastics are versatile materials widely used in various industries due to their lightweight, durability, and resistance to chemicals. However, not all plastics are the same, and it’s important to understand their properties before cleaning them in an ultrasonic cleaner.
- The properties of different types of plastics can vary, including their melting point, hardness, and chemical resistance. Here are some common types of plastics and their properties:
- Polyethylene (PE): PE is a thermoplastic that is tough, flexible, and resistant to chemicals. It has a low melting point and can be easily cleaned in an ultrasonic cleaner.
- Polypropylene (PP): PP is another thermoplastic known for its high melting point and excellent chemical resistance. It is commonly used for packaging and laboratory equipment. PP can be safely cleaned in an ultrasonic cleaner.
- Polyvinyl Chloride (PVC): PVC is a thermoplastic that is commonly used in construction and plumbing applications. It has a low melting point and can be safely cleaned in an ultrasonic cleaner.
- Polycarbonate (PC): PC is a thermoplastic known for its high impact resistance and transparency. It has a higher melting point compared to other plastics and can be safely cleaned in an ultrasonic cleaner.
- Acrylic (PMMA): PMMA is a thermoplastic that is lightweight and transparent. It has a low melting point and can be safely cleaned in an ultrasonic cleaner.
- Nylon (PA): PA is a thermoplastic known for its high strength and toughness. It has a high melting point and can be cleaned in an ultrasonic cleaner, but care should be taken to avoid excessive heat.
Temperature Sensitivity Of Plastics:
- Plastics have different temperature sensitivities, and it’s important to consider this factor when using an ultrasonic cleaner to clean plastics.
- Excessive heat can cause deformation, warping, or melting of certain types of plastics. Therefore, it’s crucial to determine the temperature limit for each type of plastic before cleaning it in an ultrasonic cleaner.
- Some plastics, like polyethylene and polypropylene, have a higher temperature resistance and can withstand higher cleaning temperatures without any issue.
- On the other hand, plastics like PVC and acrylic have lower temperature resistance and should be cleaned at lower temperatures to avoid damage.
Chemical Compatibility With Cleaning Solutions:
- Another important factor to consider when cleaning plastics in an ultrasonic cleaner is the compatibility of the plastic with the cleaning solution.
- Certain plastics can react with or dissolve in certain cleaning solutions, leading to damage or discoloration. It’s crucial to ensure that the cleaning solution is compatible with the plastic being cleaned.
- Generally, mild alkaline or neutral cleaning solutions are suitable for cleaning most types of plastics. However, it’s always recommended to refer to the plastic manufacturer’s guidelines or consult with an expert to determine the most appropriate cleaning solution for a specific type of plastic.
- Avoid using harsh chemicals, solvents, or abrasive cleaners that can damage or degrade the plastic surface.
Cleaning plastics in an ultrasonic cleaner requires considering factors such as the properties of different types of plastics, their temperature sensitivity, and chemical compatibility with cleaning solutions. By understanding these factors, you can ensure effective and safe cleaning of plastics in an ultrasonic cleaner.
Guidelines For Cleaning Plastic In An Ultrasonic Cleaner
Cleaning plastic in an ultrasonic cleaner requires careful adherence to these guidelines. Ensure not to use flammable liquids, suspend parts instead of placing them in glass containers, and avoid cleaning low-density, flexible plastics as they can be prone to damage.
Follow these tips for effective and safe plastic cleaning in an ultrasonic cleaner.
Proper preparation before cleaning:
- Make sure the plastic item being cleaned is free of any loose dirt or debris.
- Check for any cracks or damage in the plastic that could be worsened by the cleaning process.
