Hi,

I just bought a Beocenter 1 and the screen has a lot of grime and fingerprints and the anti reflective coating is not in the best condition.  How do I clean away the grime and oils without further deteriorating the anti reflective screen?

Can the anti reflective screen be restored in any way after cleaning?  Or does that involve completely removing it first and then re-applying with some product?

Hallo Friends,

the Beocenter 1 is from 2004 ...i believe there is no chance to get a new one Wink

 

Cheers,

treat this recommendation cautiously but on my Avant 55 I have cleaned it with a chemical free 'add water only' cleaning cloth. Something like this: https://www.amazon.co.uk/Minky-M-Cloth-Glass-Window/dp/B00J4LAC22

the cloth slightly damp on one side can clean the glass screen and then used the dry side to carefully buff/dry to a streak free finish. It seems to work quite well and not damage the finish due to the lack of chemicals.

If your coating is removing I'm not sure what to suggest sadly. but maybe the above gives you a starting point.

So I got some warm water and put some mild washing up liquid in it (just a tiny amount), and used one microfiber cloth to wash it down on both sides (had to disassemble the tv of course and remove the front glass, front plastic cover and back cover).

 

Once washed, I buffed it with a dry microfiber cloth.  Seems to be ok.  I cannot see that it has damaged the coating any more and all the mould is gone and the grime.  Now, the tiny spots where the coating has deteriorated are more easily visible because it's clean, but they have not gone worse.

 

Anyone know how to completely remove the rubber coating on the back case?  It was probably once quite a nice finish, but it's gone sticky with age.  I got a bottle of isopropanol but it's probably not pure, so it didn't do much.  If IPA is the only way to go, then i'll have to order a bottle of 99% pure.
