How does a DVD laser lens cleaner work?

A DVD laser lens cleaner features tiny brushes or fibers attached to a disc that gently clean the laser lens of a DVD player or optical drive. When the disc is played, the brushes make contact with the lens to remove dust and debris without causing damage. This helps improve reading accuracy and playback quality by ensuring the laser can effectively read the data on discs. Additionally, some lens cleaners may include a short audio track that guides users through the cleaning process.
