How do you clean the thermal paste on the CPU?

Im planning to buy a Zalman 9500LED cpu cooler but I have one question before i go and buy it. Right now I have the Intel stock heatsink/fan from the E6750. So if i take out the Intel stock one, the thermalpaste will be left over on the cpu. I heard a lot of ppl say use the nail polish to clean it but will it damage the CPU? Cause I thought any water that touches the CPU will damage it? or?

A small amount of Isoprophyl alcohol and a soft cloth will work fine. The actual chip is protected by the housing you will be cleaning.

So is the nail polish stuff Isoprophyl alcohol? or where can i get Isoprophyl alcohol?

No nail polish is not alcohol. Walmart, costs about a dollar for a large bottle of 75%.

Rubbing alcohol will evaporate real quick like, so you don't need to worry. Use a 100% lint free cloth (like 100% cotton) so that lint doesn't get on the cpu which will decrease surface area and so on. Clean both the cpu and the heatsink properly before applying new paste.

I just wipe it off with a paper towel, there is no need to get all anti-septic on it.
But if you have something that needs a bit more strength use 90% Isopropyl.

I keep a box of alcohol pads in my tool box as well as some cotton swabs in a bag with AS5.

The artic clean 1 + 2 combo works pretty good, but it's a bit more expensive than rubbing alcohol, which works fine also.

don't use acetone it will melt your PCB board if you happen to get some on it
