You're starting out with CPU maintenance and have a limited option: disinfectant containing 2% Chlorhexidine gluconate and 70% isopropyl alcohol. It's best to use it cautiously, as both ingredients have specific purposes and safety considerations. Always follow the manufacturer's guidelines and ensure proper ventilation when working with these substances. If you're unsure, consider consulting a professional or more reliable source.
When testing on different materials like cardboard boxes or jar lids, check for any remaining residue after evaporation. Iso alcohol is preferred because it evaporates completely without leaving anything behind. Other disinfectants or hand sanitizers often leave a film that can block the thermal paste from reaching the surface properly.
I wouldn't do it. If the remaining 30% were just water, it might have been fine with a bit more attention and drying time, but other additives could cause some leftovers.
It also mentions "2% Chlorhexidine gluconate." That's the issue. When purchasing XX% IPA (not the alcoholic beverage), it contains XX% pure IPA with the remainder being water; no additional ingredients. The alcohol tends to evaporate almost right away after wiping, while the water takes longer. That's why experts suggest using over 70% and usually favor over 95%. The lower the water content, the quicker everything dries and the reduced risk of water damage when parts are accidentally soaked.
