On flat screens and plain water

Take a piece of white cotton cloth, dip in water, wring it till no water drips off..i.e. it is just about moist. Switch off your laptop or LCD monitor. Start at the top left corner or any convenient point and in a slow circular motion very very very gently caress the screen. Repeat till you have whole of the screen covered. Now we have all the smudges and marks off the screen. Run time for the whole process - (15 - 45) mins.
Pros - Can save you the frustration caused when you log onto your computer and look at the modern art for a brief while, while the computer loads.
Cons - Time consuming and doesn't work for oily smudges.
Conclusion - To be attempted when frustration reaches its peak and/or when there r lots of free time.
