turn your computer off and open it up

take a paper towel dampened with ethyl (not isopropyl) alcohol and wipe down every bit of silicone in the machine and everything else you want to. Ethyl alcohol doesn't leave a residue and isn't conductive or corrosive to metals, plastics, nor rubbers. Let it dry for a minimum of 5 hours and you'll be set to go.

please note that i've done this to many computers/gaming consoles with ease and good results, but i am NOT responsible if you fuck something up somehow

and this is also how the car dealership i worked at cleaned car's ecu
