    Is there a decided best way of dealing with this?

    My primary problem seems to be the front edge of the laptop in front of the trackpad, since I commonly rest my thumb there, but of course, anywhere I touch it consistently will have some level of this problem.

    The last one I sold, the guy emailed me and asked if I spilled acid on it or something. (I took closeup photographs of it in the listing, but he was just curious how I could have done that.) I assume it's bacteriological. I tried wiping the places down with alcohol daily when I noticed it starting, but it didn't do anything to slow it down.

    My replacement MBP 2016 (that decided to not charge or turn on anymore after a couple weeks of use) will be arriving soon, and I'd like to get a head start on the pitting problem if I can.

    Don't eat or drink while using your laptop. Also, if you use medications or skin products they can effect your skin's pH.

    It's not a food/drink issue. It's a skin issue for a lot of people. I do this to anything metallic that I touch on a regular basis. Aluminum at least.

    I'm working under the assumption that the skin issue is still not well understood (just from previous research), and even if it were, not a feasible approach to a solution.

    i.e. I'm asking about films/skins/coatings/etc that can be used. Or something similar that Apple doesn't recommend against already.

    In theory you could cut a large screen protector to fit the area but the trouble with that is you don't know if the glue would cause issues.

    Maybe something like the BestSkinsEver MBP skin might work?

    Thinking about getting it for mine to prevent stractches/dings around the edges and wrist area.

    Sweat/oils on hands are slightly acidic iirc. Forensics 101, every time you put hands on keyboard (anything) you put a little of yourself on it and you get a little of it on you.

    Not to mention, watch bands, bracelets, rings.

    Was just about to say the same, I work in Printable Electronics and the acidic levels from sweat/oils can cause "damage" to metals over time, we even interleave with acid free paper for packaging purposes to avoid the same types of issues.

    I would also advise some type of protective skin to cover the inside of the laptop as that should stop this happening.... or you could always wear gloves lol

    Biology 101, we leave far more than ourselves on things we touch at all :) (And take a lot of other things obviously. A common first semester biology lab assignment is swabbing keyboards to demonstrate-to/horrify the students.)

    Either I'm a xenomorph or my bacterial cloud if you will generates more acidity than normal. I know it's one of those; I'm just not sure which. I just know it's drastically out of the normal range, because anytime someone sees what I do to metal, they ask the same kind of question "Did you spill some kind of acid on this?"

    Anyway, a film seemed the obvious approach, but I thought I've read where Apple recommends against such things.

    Considering the worst location is that little indent on the front of the base, a film would be a difficult solution. I wonder if there's an acceptable liquid/paintable film. i.e. a thin clear coat at least for that location. Normal films for the sides next to the trackpad seem obvious, but again, I feel like I've read from Apple that's typically a bad idea. Screen damage etc. Maybe I'm thinking of something else like keyboard covers though.

    My primary reason for being concerned with this isn't cosmetic so much as resale. I generally sell my previous laptop when I get a new one every 2-3 years, and it's not fun having to say basically: I swear by whatever your value equivalent to an immortal soul is, I didn't spill anything on this. This is just from my touching it >.<

    I used a Moshi pad to halt the pitting on my old 2011 MBP.
