How to clean the tape residue from cpu case. I had big sticker sticked by the manufacturer on it. I removed and still the part is sticky and looks ugly. I tried to wipe that out with a cloth. But the minor threads stucked on it and the same is no more visible. It looks ugly. I want a complete empty clean surface. What can I do to wipe this out. I tried a number of things here, but that does not work. I am planing to purchase some simple cleaning kit, but I am not sure what to use. It should wipe out the paint or design on cpu case.
