LCD Cleaning gone bad... please HELP!

I get those marks on mine, but they aren't permenant. I use a damp cloth, immediately followed by a very soft, dry cloth to buff it out. Once it dries though, the marks are there, have to get it wet again to remove them.

He's saying that the marks are not permanent, but if, after lightly buffing, marks remain, you'll need to repeat the process: damp cloth followed by gentle buffing with soft dry cloth before the screen dries completely.

I use kgbeezr1's method to clean my screen, too. However, I've never spayed air onto it, so never had liquid like you describe, on my own screen. Not sure what sort of liquid would shoot out of a can of compressed air. Propellant?

Good luck.

sounds like the a FREON type agent inside the canned air. I've used canned air for years and every can has that cool blast of moist air come out if you tilt or shake the can in the slightest while using it. I wouldn't use it on my monitor, I bought a soft artist paint brush for that (wal mart craft dept) and use only monitor wipes for the actual screen.

That 'freon' (if that is what comse out) is a godsend to those of us who overclock. I've had a CPU get so hot to the touch that I thought it was gonna fry and a quick blast with that arctic moisture and it turns the heatsink into ice. Not so sure how good that is for any overspray that might hit other compenents, but it's saved me from frying a cpu a time or 2.

When using a can of compressed air, the liquid residue left behind is water and it comes from air...as in what's in the atmosphere, not what's in the can.

The can's contents are rarely breathable air (which is actually mostly nitrogen).

The compressed gas inside the can is actually a liquid because it's compressed at high pressure. It's *NOT* water. Water is a liquid at room temperature and can't be compressed. The compressed gas then has a very low boiling point meaning that it vaporizes at room temperature. More to the point, if the compressed gas were not compressed it wouldn't shoot out the can when released.

In other news, as a compressed gas is released into the atmosphere it expands since atmospheric pressure is way lower than the pressure inside the can and as soon as the compressed gas hits the atmosphere it boils. Now as a compressed gas expands it cools down and as compressed gas cools down it can condense any gaseous substance suspended in the air (like water molecules) into liquid water or into solid ice depending on such variables as relative humidity as there must be adequate gaseous water molecules to condense, the type of compressed gas, and naturally the temperature differential caused by the release of the compressed gas.

That's why it's possible to take a can of compressed air, shake it vigorously, turn it upside down and freeze stuff with the escaping gas.

It's worth noting that there's a serious danger of frostbite and property damage if doing this.

The Stain may be inside the monitor and the LCD glossy cover. if so you will need
to remove the clear protector over the LCD and clean inside.
If its not inside use a Micro Fiber Cleaning cloth like the ones used on
sunglasses.
clean the screen with LCD cleaner.
Its a foam so it will not get into you screen

It's never a good idea to disassemble an LCD...any dust that gets onto the backside of the LCD glass where the CCFL backlighting shines through will show up as real annoying dark specks.
