How to clean glasses with oil?

The best way is to go to the optical shop and let the staff use ultrasonic cleaning. If you feel trouble, you can also use a paper towel dipped in wind oil to wipe it, but the effect is definitely not as good as the former.

In optical cold working, lens cleaning mainly refers to the cleaning of residual polishing solution, adhesive and protective material after lens polishing; Cleaning of grinding oil and glass powder after lens grinding; Clean fingerprints, saliva rings and various attachments before lens coating. The traditional cleaning method is to use wiping materials (gauze, dust-free paper) and chemical reagents (gasoline, ethanol, acetone, ether) for manual cleaning by soaking and wiping. This method is time-consuming and laborious, and its cleanliness is poor, so it is obviously not suitable for modern large-scale optical cold working industry. This forces people to look for mechanized cleaning methods. Therefore, ultrasonic cleaning technology has gradually entered the optical cold working industry and exerted its talents, further promoting the development of the optical cold working industry.

The basic principle of ultrasonic cleaning technology can be roughly considered as a method to make a series of physical and chemical changes in substances with the cooperation of cleaning media by using the huge force generated by ultrasonic field, so as to achieve the purpose of cleaning. When the high-frequency vibration higher than the sound wave (28 ~ 40kHz) is transmitted to the cleaning medium, the liquid medium will produce nearly vacuum cavity bubbles under the high-frequency vibration. In the process of collision, merger and extinction, cavity bubbles can locally produce thousands of atmospheres of pressure, and such a large pressure will cause a series of physical and chemical changes of surrounding substances. This effect is called "cavitation"
