Anybody ever clean burner head?

Has anybody ever cleaned a burner head? I have a BenQ 1655 that seems to have more and more problems reading movies that my old, slow laptop internal reads just fine. Getting many more coasters. This guy has burned about 150 - 200 dvd’s and may just be getting dirty?

Burner head???

Nope, this is a PUH.

Use a lens cleaner.
