Question MSI GE63 8RE Laptop Corrosion - Should I clean it? or safe to leave it as is..?

[n0kia99]

MSI RMA service center came back to me with these pictures. Safe to leave it? or should I clean it with something? tips?

Side question..
On the last picture.. the thermal paste looks white.. I re-pasted before with grizzly thermal kryonaut. I don't remember it ever looking that white and runny like poop.
Anyone else use grizzly and does it look like that on yours?

I would clean it with isopropyl alcohol. The corrosion could be conductive and cause issues.

3rd pic looks like water corrosion had this so many times on a motherboard. I always used isoprophyl alchoho +90% like previous poster said and dipped clean toothbrush into alcohol and gently scrubbed it away. Sometimes only Q-tip is not enugh to get under chips and corrosion , just dont use too much force with toothbrush and softest head you can find for it.
