How to Clean Blu-ray Lenses

A non-cooperative Blu-ray player that frequently skips or won't read content may be malfunctioning because of a dirty lens. Dust and debris can work its way into your machine and obstruct the lens; removing the obstructions fixes the problem. Cleaning a dirty Blu-ray lens can be as simple as inserting a cleaning disc or as complicated as disassembling the drive; however, the process always comes with a damage risk.

Step

Insert the cleaning disc, press "Play" and follow the onscreen instructions.

Step

Remove the cleaning disc and test the drive. Stop here if the drive works.

Step

Blast the lenses with compressed air to remove debris. If possible, expose the lens and spray from a few inches away. If the drive will not expose the lens, pop open the tray and spray the compressed air alongside the entire opening.

Step

Test the drive and stop if it works.

Step

Wipe off the lenses with an isopropyl alcohol (91 percent or greater) damp cotton swab or cloth if the drive still won't work. Gently wipe the lenses using a cotton swab if the drive can expose the lenses. If the drive uses a tray or slot loading mechanism, wrap a clean credit card in a cotton cloth, insert the credit card into the opening and slowly drag the credit card from side to side.

Step

Test the drive; if it still doesn't work, either bring the device to a repair professional or disassemble it yourself to directly wipe off the lens with an isopropyl alcohol damp cotton swab.
