Cleaning a screen - use spray polish or microfibre?

Maybe you didn't use enough, or the cloth wasn't clean.

No, an LCD screen is not like a CRT screen, it's some sort of plastic
material, and I have since read that the manufacturers say not to use
Isopropyl alcohol on LCD screens. I just use warm water and it works
fine.
 
Isopropyl alcohol and a soft cloth. This method is safe for
CRTs, TFTs, LCDs, and every other type of monitor (and coating)
out there. It is also cheap, effective, and widely available.

I used to use this but it can leave such a dry surface that the final
polishing off can create static.
 
I hack a lugie on mine and then lean forward and wipe it dry
with my shirt sleeve being careful not to scratch it with cuff
buttons.


I dread to think how you clean your keyboard!

Isoproply alchol can disolve some plastics although not very quickly
so you could be softening up the plastic surface and searing it
slightly.

For glass I've used window cleaner for years, usually the ones that
are vinega based. [1]

I've used a dry cloth with a fine spray of window cleaner on before
fine.

Of course the easy solution to this is to get one of the plastic or
glass screen protectors and put that over the screen. Its not perfect
(as there is a slight airgap) but it keeps most of the dust off and
gives the screen a little protection.



[1] or with uric(?) acid, although wiping my screen with 2nd hand
wee-wee doesn't seem right :-)

Never use Isoprpyl alcohol on an LCD screen though. It will make it
very streaky. I tried it once and had to wash it iff with water.

Hmm. The purpose of the alcohol is to absorb all the water. The

word in question is miscible.

My Sony manuals say not to use any solvent, alcohol specifically listed as a
no-no, because it can damage the thin coating on the surface. It says to
use a soft cloth, moisened if necessary with a "mild detergent solution"
like hand soap. I've found that a tee shirt lightly moisened with water
works well.

Hooray---I can't believe all of the suggestions on this thread. You're on
the right track though. Why all of the fuss? After seeing my optician
carefully wipe a new pair of glasses with paper towel (dry), I just use
paper towel, dampened in one corner with wet fingertips. Run the dampened
portion across the screen until all is covered, then use the rest of the
towel (folded) to wipe it dry. Works for me.

Two bits of advice:

1.) Find a new optician - one who know and cares.

2.) Stop using wood-based paper towels.

Doesn't the combo of soap and hard water (in some areas) leave a
visible smear of calium stearate scum?

It certainly does around here as I alluded to earlier:

'Citric Acid' - doh!

My teenaged son and his friends are always running their fingers on
his monitor screen - fingers shiny from the gook they put on their
hair to achieve that boy-band look. I tried plain water, industrial
spirit (ethanol-methanol), window cleaner fluid, household detergent,
plain soap. Nothing worked, they just spread the gel over the entire
screen.

Then I got an inspiration : Clean, dry soft cloth. It works. Needs
some vigorous rubbing though, and that can't be too good for the
coating. Maybe I'll try the vinegar stuff next time. But I wonder if
the acid might do some harm with regular use.

Its worked fine for me for years now using varying things from the
cheap local shop stuff to more expensive brands. Citric acid, e.g. a
drop of lemon juice will also work well as a degreasant.

I don't care what the purpose is, it made the LCD screen streaky. You
going to argue with the facts?

Yes, citrus cleaners work well and are safer for the environment. When
I worked in the printing trade we used a citrus hand cleaner to get
the ink off (smelled like oranges which was pleasant) and it worked
really well and didn't dry out your skin like some of the other
industrial cleaners do.

The scum forms when calcium sulphate reacts with sodium in the soap, I've
never had this problem in any of the places I lived. I don't touch my
screen and I stopped smoking years ago, so I rarely need to clean my
monitor. If I had to clean it often I would probably use a cleaning spray,
but dish soap and water works fine for me, you do need to dry the screen
with a paper towel afterward.

Try it on your son's head <g>.

My son is six. When he touches the screen, it is not something from
his hair that gets left on the screen, but his nose (yuck).

Kids eh?

Sometimes I just have to touch the glass screen of my VDU to work
through some data. Yeah, I know it's not a good way of keeping the
screen clean.
How do you guys keep the screen clean after it has got greasy? I
used to think using a microfiber to life the grease off the screen
was best. All the microfiber advertising suggested it was the very
best.
But now I am coming round to thinking that the old way of using a
spray furniture polish or spray glass cleaner is better than
microfibre.

Matches my experience.
There are also some proprietary screen cleaner out there (not wipes
but sprays) and I wonder if anyone can say how they compare to the
other methods.

Yes. I have one from "vivanco" (blue stuff in platic bottle).
Works incredibly well on CRT and LCD. Wipe dry with paper
hanky (Tempo is preferred, other brands suck).
Finally there is general purpose denatured alcohol (methylated
spirits in the UK) but I am not so sure about using this method.

O.k. for CRT, mediocre cleaning result. Don't use on LCDs.

For screens (and windows) rather than a paper (or cloth) towel, use a
squeegee (sp?) (memo to self: too many ()s)

It's hard to get glass completely clean with a cloth or paper towel; a
lot of the dirt just gets smeared around. The squeegee strips away the
water/solvent/soap/gunk from the glass where it can be removed from the
rubber blade with a paper towel.

Look for the little 3-inch wide models. Very, very handy for doing the
insides of car windows, as well.

Note: Be careful if using it on a monitor screen. A film of water that
doesn't run/drip by itself will collect in front of the squeegee blade
into a small puddle that *will* run/drip. Work from bottom to top and
keep the angle of the blade tilted towards the vertical mid-line of the
screen where the overflow can be caught with that handy paper towel.
 
yes graham paper towels and the monitor screen damage thing is like
the Colorado carving the grand canyon not in your life time...
