Hello everyone, I purchased the white version of the m17 R2 a while ago, and with time and use, it started darkening in the parts where I let my hands rest the most while typing and somewhere also behind the screen. I tried cleaning it with water but because it's caused by skin oils it was to no avail. I read that using Isopropyl Alcohol would fix it, however since I am not 100% sure of the materials the chassis is made out of, I wanted to make sure I won't be melting away the paint if I were to clean it with that. Any suggestions?

Thanks in beforehand!
