CD laser: clean the lens

If the CD player hangs again or often or does not even recognize CDs: Do not throw it away or rumkloppen it (this only works with televisions).

Unscrew the CD player and move the carriage, on which the CDs come in and out, in such a way that one reaches the laser lens (do not stare at it during operation, otherwise blindly ...).

This is best done with a bent cotton swab, which has previously dipped in distilled water (hardware store, pharmacy) (it should not drip, wet enough).

With this you rub off the lens (repeat if necessary) and let it dry completely.

It worked great for me. If not, you can still rumkloppen on it.
