Hi

Soon im going to get the monitor out of my Astro and was wondering what is the best way to clean the monitor ? im going to use a air duster and ESD brush for the chassis but im a little worried about the aquadag, i want it to look nice and clean but obviously dont want to ruin it ;)

Thanks

I think I've ask the same some time back...
Go with the air and the brush and use a towel and maybe some alcohol for the tube. I wouldn't wash anything with water. It doesn't take long till there is new dust.

I never washed a tube but I always wash my chassis. There is no problem as long you make sure they're 100% dry before you plug them back.

It makes it a lot easier for repairs and detect dry joints, for example.

Hydrofluoric acid bath.

Hydrofluoric acid won't eat through plastic. It will, however, dissolve metal, rock, glass, ceramic. So there's that


As quoted by Walter White :awe:

Some guy on another forum dunked his MS-2390 chassis in an ultrasonic bath :eh:

I'm sure it came out clean.

There are parts that aren't sealed and once water gets in it takes a lot of time to get out and may leave an unwanted calcareous residue which may have bad effects later:

1) LOPT/Flyback. The front block with the screen/focus trimmers. The hole where the HV lead comes out from.

2) PTC

3) CRT socket

4) Transformers/coils not fully encapsulated in resin

5) connector housings (especially if unplugged)

6) fuse holders (with fuse left in)

etc.

Now, I do wash my chassis but only after desoldering the critical parts (which I may wash and carefully dry individually with compressor and hot air and other precautions). But hosing the whole monitor in the garden and then leave it there to dry as you see in dumb youtube videos? No F***ing way.

Nothing works better than a hammer! When the tube implodes, the air displacement is sure to get rid of all the dust! :lol:
