The Dangers of Cleaning a Watch Movement with Alcohol in an Ultrasound Cleaner Without Disassembly

Consumers and hobbyists often seek quick and convenient ways to clean their watch movements, but using an ultrasound cleaner with alcohol without properly disassembling the movement can lead to significant damage and issues. This article will discuss the potential risks involved in this practice and recommend the correct procedure for maintaining your watch.

Damage to Components

The use of an ultrasound cleaner with alcohol without adequately disassembling the watch movement can result in damage to delicate components such as gears, pivots, and other small mechanisms. The high-frequency sound waves in the ultrasonic cleaner create cavitation bubbles that, while effective at breaking down dirt and debris, can also cause microscopic damage to these fine parts.

Residual Cleaning Solution

Another significant concern is the potential for residual cleaning solution to remain within the movement. If the movement is not fully disassembled, cleaning solution may become trapped in various areas, leading to corrosion over time. Even more critical is the need to ensure that all alcohol has evaporated thoroughly. If not, it can leave behind residues that promote corrosion and other detrimental effects.

Lubrication Issues

A major consequence of using alcohol and an ultrasound cleaner without disassembly is the complete removal of existing lubrication from the movement. Watches rely on proper lubrication to minimize friction and wear. Running the watch without reapplying the appropriate lubricants can lead to increased friction and wear, resulting in potential damage to the movement.

Water Resistance

Water-resistant watches rely on seals that must remain intact to prevent water ingress. Ultrasonic cleaning can compromise these seals, leading to potential future water damage. Thus, if a watch is water-resistant, ultrasonic cleaning should be avoided to maintain its long-term functionality.

Electrical Components

Electrical components within a watch, such as quartz movements, should be treated with caution. Using an ultrasound cleaner with alcohol can damage these parts, especially if they are not designed to withstand such treatment. Ensuring that electronic components remain intact is crucial for the overall functionality of the watch.

Conclusion

In summary, cleaning a watch movement in an ultrasound cleaner without disassembling it poses significant risks. To properly clean a watch movement, it is recommended to follow these steps:

Disassemble the movement carefully. Use a watch-specific cleaning solvent. Clean each component thoroughly. After cleaning, reapply appropriate lubricants. Inspect the movement for any mechanical issues. Reassembly and testing before returning the watch to use.

If you are not confident in your ability to clean a watch correctly, it is best to send it to an authorized watchmaker. They have the expertise and tools to ensure the watch remains in optimal condition.

Final Thought

Just placing an entire movement into an ultrasonic bath is not only ineffective but could cause irreparable damage. Proper disassembly is essential to ensure that the entire mechanism is cleaned effectively and that all components remain undamaged. If you're a watchmaker yourself, it's best to adhere to these standards to preserve the longevity and functionality of your watches.
