Tips for cleaning moldy best lens

Mild mold stains can be cleaned by oneself, while severe mold stains require professional treatment
Mold on best lens is a common problem among photography enthusiasts. Mold not only affects the quality of photography, but may also cause permanent damage to the lenses. The following are cleaning techniques and preventive measures for different mold conditions:
1、 Cleaning methods for mild mold stains
Use professional cleaning tools
For slight mold stains on the surface of the lens, lens cleaner and lens paper can be used for cleaning. First, gently wipe the surface dust with lens paper, then spray an appropriate amount of cleaning agent, and wipe with another clean lens paper until the mold is removed. ‌
If there is no professional cleaner, you can use anhydrous alcohol combined with lens paper to wipe, but be careful of the corrosiveness of alcohol to ensure that the lens is completely dry. ‌
Cleaning steps
Use a brush and pen to remove floating dust from the lens and body. ‌
Use an anti-static cleaning cloth to wipe the lens clockwise and unidirectionally to remove fingerprints and grease.
2、 Suggestions for handling severe mold stains
Professional maintenance
If the mold has penetrated deep into the lens, it is recommended to send it to a professional repair shop for processing. Repair shops usually have professional equipment and skills, and may solve problems by replacing lenses or the entire lens.
Disassembling and cleaning the lens by oneself may result in inaccurate packaging or further damage, therefore it is not recommended for non professionals to operate. ‌
The use of mold clearing solution
For stubborn mold spots, you can try using mold cleaning solutions such as 530 electronic cleaning solution or Kumamoto Chemical's mold cleaning solution. These products have minimal damage to the lens, but must be operated strictly according to the instructions. ‌
3、 Measures to prevent mold stains
Keep dry
Store the lens in a dry environment, avoiding moisture and high temperatures. Moisture proof boxes or desiccants can be used to reduce humidity.
When not in use for a long time, store the camera in a moisture-proof box. ‌
Regular cleaning
Regularly clean the surface of the lens, remove dust and dirt, and reduce the possibility of mold growth.
In humid environments, increase cleaning frequency and use moisture-proof tools to protect the lens. ‌
4、 Precautions
Avoid using chemical cleaning agents: Strong acid and alkali cleaning agents may damage the lens coating and should be avoided.
Gentle operation: Avoid applying excessive force during cleaning to avoid scratching the surface of the lens.
Timely handling: If mold spots are found, they should be dealt with as soon as possible to prevent further spread of mold. ‌
By using the above methods, it is possible to effectively clean the mold on the camera lens and prevent its recurrence, thereby extending the lifespan of the lens.
