Best Projection TVs

How do I clean the lenses on the inside of a projection screen tv, I got a used tv and have cleaned everything else but there is a lot of dust on the lenses themselves, is there any way to clean them without screwing up my tv?
The dust is inside the lenses themselves, can I take them apart without messing them up?

I don’t want it dusted, I want fingerprints off of it.

There is a really annoying really really small black spot on my rear projection screen and I think it is on the inside of the screen. It does not appear to be a nick on the front so I am guessing it must be something stuck to it from the inside…hmmm I want it gone.
10 points to anyone who knows any cool pointers.

I have been told you are supposed to use special clothes and not to use windex on it. I need to know what kind of clothes these are and where to get them. What is the “technique” to wash a big screen tv? Thanks!

i have already taken the screen off, and the dust is under the lens and everything looks sealed, but my picture is so bad and you can see a lot of dust in there…. help, also i took one bolt off and some oily stuff came out whats that?
