It works very well, better than isopropyl alcohol.
I needed to clean my CPU and considered using isopropyl alcohol to do it. However, when I used it, I wasn't really satisfied by the result. I could still see residue of thermal material. So I tried this instead and it worked on all CPUs since. It cleans very thoroughly for best results and has a capacity to be used at least more than 6 times. My only problem with it is that the white canister liquid makes me get headaches and nauseated so don't breath too much of it in.
