Cleaning laser lens; good idea?

leave it alone unless you have problems.
The old saw: "If it ain't broke don't fix it!" applies.
When you can just as easily make it WORSE than better, better to do nothing!
My way of being certain that the lens stays clean is to use a clean cosmetic blush brush on every silver disc (CD DVD) I put in. The dust stays out of the player, by keeping it OFF the discs.

Is that brush made from organic or synthetic bristles E?Thanks,Bob

A make-up brush is a great idea, although I might get the wife to buy it for me; might get some odd looks!
I would assume natural fibres would be better, as synthetic might cause a static charge on the disc and attract more dust.

I actually am not certain. I have used two different brushes. One was fine as is. the other I am pretty certain it was animal bristles, as I 'softened' the tips with a bit of emery paper as the brush felt a little harsh to my fingers. After fragmenting the tips with the emery paper, it was fine.
For the elite, may I sugest a sable fine arts paint brush. A nice wide and full bristle one would cost at LEAST $400.00
A nice synthetic sable paint brush could be had for under $100.
Cosmetic brushes range from $10 to $40.

Horse hair is used for camera lenses. make sure the bristles are not touched.
