Been using it for years.
I've been building gaming computers for over 10 years and have been using this stuff ever since. I will admit that it is pretty scary when you're removing old thermal paste that is silver based  (super conductive) because you could fry something. But that's not at the fault of the cleaners. Just be careful and this will get the old stuff right off, no matter what it is and how long it's been caked on there.
