Worked great to clean up old paste and prep the CPU and heatsink for new grease
This two-part system works great and well work having. I used ArctiClean 1 to remove the 9-10 year old dried up paste in two of my old PCs, and it did a great job. All that was left after cleaning and removing the old paste was a little bit of black residue on the aluminum heat sink, and that was removed by using ArctiClean 2. I used some new carbon-based thermal paste and reassembled my PCs, and both are working good and the CPU in each machine is running cool.<br /><br />If anyone is planning to do what I did and replace old paste on the CPU, and the CPU heatsink fins have any dirt or dust that can't be brushed or vacuumed away, I would highly recommend cleaning the heatsink fins with a cleaner safe for aluminum and a soft brush. I used a spray cleaner specifically made for A/C coil cleaning, as many household cleaners will cause aluminum to start to corrode after being exposed to them. I applied the cleaner to the heatsink, brushed the fins, then rinsed with water and let the heatsink dry before putting it back in the computer.  I also wore an ESD control wrist strap and line clipped to the chassis when I worked on my PCs.
