Are the screens on the DNA40 really made of glass?? I (ignorantly) assumed they were made of plastic. I want to clean the (unprotected) screen on my Flask more often, but I am afraid of scratching it all up.
BNEAT,
I don't know if they are glass or plastic but they are coated with some optical medium so be carful with what you use to clean it. I have had great luck with a soft cotton tip swap (not the six inch stick type) and the cleaner they sell for cleaning TV screens. I wouldn't even use tap water because where I live the water is so hard it has rocks in it and Windex has ammonia which can play havoc with the optical coating.
Soft cotton swabs and no scratches - so far.
