So, I was doing a routine cleaning on my MacBook Pro and I notice something on my palm rest that seem disconcerting. I don't think I noticed it before because of all the junk that's surrounding the laptop (papers, books, etc) but this just looks weird. The palm rest is smooth. I tried cleaning it using Soap and Water but didn't work. Tried Magic Eraser, didn't work. My last bet now is to visit the Apple Store and see what they can do. However, I'm wondering, how would Apple respond to this? Would they try to blame this on me saying I caused it somehow? The rest is completely smooth.
