Ultrasonic Cleaning Machine and Coated Glasses: What You Need to Know

Ultrasonic cleaning machines have become increasingly popular in recent years due to their ability to effectively remove dirt and grime from various surfaces. One area where ultrasonic cleaners have proven particularly useful is in the cleaning of coated glasses, such as those with anti-reflective or scratch-resistant coatings. In this article, we will discuss the benefits of using an ultrasonic cleaning machine for coated glasses and provide some tips for effective cleaning.

Working Principle of Ultrasonic Cleaning Machine

Ultrasonic cleaning machines use high-frequency sound waves to create microscopic bubbles in a cleaning solution. As the bubbles collapse, they generate high-pressure waves that can penetrate even the tiniest crevices and remove dirt and contaminants from surfaces. The cleaning solution used in ultrasonic cleaners is typically a mixture of water and a mild detergent, although specialized solutions may be used for specific applications.

One of the primary benefits of using an ultrasonic cleaning machine for coated glasses is that it is a gentle and effective cleaning method that will not damage the delicate coatings. Traditional cleaning methods, such as wiping the glasses with a cloth, can scratch or otherwise damage the coatings, reducing their effectiveness and lifespan.

Ultrasonic cleaning is also a time-efficient process that can clean multiple pairs of glasses simultaneously, making it an ideal choice for busy optometrists, eyewear stores, and other businesses that deal with glasses on a regular basis.

Tips for Effective Cleaning

To achieve optimal results when cleaning coated glasses with an ultrasonic cleaning machine, it is essential to follow a few basic guidelines:

  1. Choose the right cleaning solution: It is important to use a cleaning solution that is suitable for the type of coating on the glasses. Check with the manufacturer for recommendations, or use a specialized cleaning solution designed for coated glasses.
  2. Use the correct frequency: Different frequencies may be used for different applications, and the appropriate frequency will depend on the type of coating and the degree of soiling. Consult the manufacturer’s guidelines to determine the best frequency for your needs.
  3. Avoid overcrowding: Do not overcrowd the ultrasonic cleaning tank, as this can reduce the effectiveness of the cleaning process. It is best to clean one or two pairs of glasses at a time.
  4. Rinse thoroughly: After cleaning, be sure to rinse the glasses thoroughly with clean water to remove any residual cleaning solution.


Ultrasonic cleaning machines offer a safe, efficient, and gentle method for cleaning coated glasses. By following these tips and guidelines, you can ensure that your ultrasonic cleaning machine is used effectively and that your coated glasses remain clean and free from damage.
