I had baby oil on my fingers when I used to my keyboard on my MBP. I noticed it immediately, and it only got on two keys. I tried to wipe it up, and got most of it off. I don't think that any of it went inside under the keys though. The keys still work, and I'm using the MBP now. Since it's not a problem now, could it become one later? When I googled this, I actually found that some people clean their keyboards using baby oil, so does that mean its safe? However, if by chance, it did get under the keys, what would happen, and would it be serious? What should I do?
