is it safe to use 70% isopropyl rubbing alcohol to clean thermal paste

Solution


Preferably something that won't leave any fibers behind.
Coffee filter, old t-shirt, etc.

Most people probably use pure isopropanol? No need for overpriced specific cleaning stuff, and the 70% stuff is just not quite as good.

@OP it's safe, but pure isopropanol would be better. The less pure stuff can leave a slight residue and potentially affect cooling a little afterwards.

The only "problem" with 70% is that the extra water will take a while longer to evaporate. Quicker drying time is the main motivation for using more volatile solvents. Many PCB assembly plants use water-soluble flux for assembly and mostly water as the PCB cleaning solvent. Distilled water is also fine as long as you didn't spill salt or anything else water-soluble that can make it conductive on the board.
