Cleaning alcohol for GPU/CPU

I want to reapply the thermal compound on my graphic card since the temp is getting higher and higher by time. I found out before reapplying the thermal compound, cleaning alcohol was used to clean the surface of the gpu chip. Is this alcohol same as the one that normally found in the pharmacy?

i recommend what i use, Arctic Silver ArctiClean 2

Thanks for the info guys... I think I would just use the alcohol from the pharmacy since it is more easy to find.
