Hi Peter, :welcome: to IceInSpace.

Do you specifically mean the mirrors, or the inside of the tube itself?

For the mirrors, check out Cleaning the Mirrors of a Newtonian Telescope (http://www.iceinspace.com.au/index.php?id=63,345,0,0,1,0).

If it's inside of the OTA, why is it dirty and what is it? Dust? Spiders?
