Dear Members

My 2021 Me thought that it is a good idead to use Thermal Grizzly Conductonaut instead of normal Thermal paste, don't ask why.. I have taken apart this system about a year ago and never managed to take care of the the parts.

There is stuck conductonaut on the copper plate of my ASUS LC360 Aio and also on my i9 10900KF CPU. Does anyone have any recommendation how to clean it off so I can reuse the system for a second PC?

What I have tried so far:
– isopropanol 99%
– an old plastic debit card

Would it be okay to jzst slap thermal paste on it to make it work again if I can't get the liquid metal off?

Thanks in advance.
