just use any clean cloth, wet it, only a little bit and then wipe your monitor, I've done that over 20 times on my LCD and it work fine and makes it completely clean. There is no need to waste money on any cleaning product.
I don't have to spend one penny on anything. The antistatic cloths you toss into a clothes dryer are great for seeing dust wiped from various things like you tv set as well as an lcd monitor.
When using liquids then you start seeing smears on the screen no matter what is used it seems. There will always be some streaks of one type or another.
Maybe not, but if you knew me, you'd know how cheap I am. Well cheap in some ways. Always trying to save myself some money, I am. That way I have more money to spend when it counts.
