The fact the internet actually works at all is nuts.

80% isopropyl alcohol. Use a soft brush wet with some of the alcohol. Brush around the affected areas. Let it dry and that’s all for me.

I wouldn’t recommend dousing electronics in less than 90%. Feels sketchy. But I have nothing to back that up besides “electronics cleaner” being 99% iso.

Practice, imo. You can begin interactions with the mindset of “I want to make friends” and get used to that idea.
