Projector Clean

[Llamatron]

The company that installs and services our projectors and interactive whiteboards is charging �160 to perform a 'deep optical clean' on one of the projectors.

What on earth is a deep optical clean?

The cynic in me is sure that they just open it up, vacuum out the dust and use a bit of Windolene on the lense.

sounds about right

[Llamatron]

Are you saying that because you know or are you just being a cynical old fart like me?

[ugly_bob]

just cynicism I think. Can't see what else they'd do though.

Maybe to properly clean up a projector it has to be done in one of those special clean rooms to make sure no dust gets inside.
Or maybe it's just a con.
