The projector lens is one of the core components of a projector, and its cleanliness directly affects the image quality. Dust, dirt, or fingerprints on the lens surface can lead to blurry images, color distortion, or spots, thereby compromising the viewing experience. Therefore, regularly cleaning the projector lens is an essential practice to maintain the device’s performance and extend its lifespan. Below are detailed steps and precautions for cleaning a projector lens.

Preparation
1. Power Off the Projector
Before cleaning the lens, make sure to turn off the projector and unplug it from the power source. This step is crucial to prevent any accidental damage to the lens or electrical hazards during the cleaning process.
2. Gather Cleaning Tools
To clean the lens, you will need some specialized cleaning tools, such as lens cleaning paper, lens cleaning solution (free of alcohol and acidic/alkaline components), soft cotton swabs, or non-woven fabric. Avoid using rough tissues or cleaning agents with chemicals, as they can scratch the lens surface or damage its coating.
3. Choose a Suitable Environment
It is best to clean the lens in a clean, dust-free, and well-lit environment. Avoid cleaning in dusty areas to prevent new dust from adhering to the lens during the process.

Cleaning Steps
1. Blow Off Dust
Use lens cleaning paper or a dust blower (a common cleaning tool) to gently blow away loose dust from the lens surface. When blowing, maintain a certain distance to avoid spraying saliva or moisture onto the lens. This step aims to remove loose dust from the lens surface to prevent scratches during the subsequent wiping process.
2. Wipe the Lens
If there are stains or fingerprints on the lens, you can use lens cleaning solution. Apply a small amount of the solution to lens cleaning paper (do not drop it directly onto the lens to prevent liquid from seeping into the lens). Then, gently
