So I bought this MacBook 13 M3 in midnight color in November 2024. Mid use, I only use it once or twice a week. Lately I’ve been seeing this big grease stain where I put my hand to work and I can’t clean it with anything. I’ve tried diluted alcohol and a tiny bit of soap in a cotton bud, nothing works. What should I do? Also I’ve been thinking of getting this clear cases but they say they are bad for the screen, should I get it?
