Magnavox 51mp392h screen cleaning

does anyone know how to clean or is there any special cleaning
products for a Magnavox 51mp392h projection tv, it seems to have some
type of mesh covering on it, what i have been doing is taking a wet
cloth and cleaning each indviual spot. i have 3 small kids and as you
can imagine they are always get little drops of liquid on it. this has
been working but it takes a long time to clean each spot, i have
searched on the internet but no luck so far, any help you can offer
would be nice. also i seem to have one speaker blown, i have surround
sound hooked up so its no big deal just wondering if there was some way
to change the speaker.

thanks Blazer
