a guy was here today fixing my tv and he opened it up. I looked inside and noticed that the tubes and mirror had dust on them. not that much, but a certain amount, that surely will accumulate over time.

my assuption is that this will interfere with the video quality, causing grainy-ness.

any ideas as to whether it is a good idea to clean and how?

thanks,
ravi

Could you not used some good compressed air, that is what I use on my LCD projector in the even dust blobs start forming?

Just make sure you keep the can upright.

the mirror is quite fragile so i would go in there with a papertowel or something as you could scratch it. Personaly i wouldnt touch it. You should be alright cleaning the lenses though.

Aaaaag! Not Not NOT a paper towel! Unless you want to scratch it. Any of it... The microfibre cloths used for cleaning eyeglasses and such should be fine, I would think.

I'm really, really glad you meant to say it... and you didn't think a paper towel was proper for the job!

i'll side with sirquack here. i think that pressurized air in a can that you use for cleaning the insides of a computer would work well in this instance.
random thought- would some of that electronics-specific Endust be good for this situation?

WATCH WITH "BLOW CANS"... if it siphons and you blow liquid on it, it'll leave a film.

As a glasses wearer (and a frequent cleaner of scanner mirrors when I smoked in my last house), the best cloth for cleaning lenses and mirrors is actually a well-used but clean tea towel (don't use fabric softener).

If you have a local camera store, buy some lens cleaning tissue or a lens cloth. I wouldnt use anything else when optics are involved.
