Ive unplugged everything and gently wiped it down with a cloth but it’s still stained on the wires. (Last pic is it after I gently rubbed it with a cloth)

From what I see nothing got on the motherboard or the gpu luckily but still I’m just really worried

She does normally put stuff on top of my PC but I just tell her not too as it will restrict airflow but maybe I should have been more firm 🥲

I’m not angry at her, she is my mom and it was an accident but man this really sucks and I hope it’s not permanently damaged.

Does anyone know how to clean it or what I should do next?? I don’t know how to clean the stains..
