I searched this (I know cleaning threads are frequent, so please hang in there with me) and found a lot of helpful information but I have questions that don't primarily focus on what to clean with (although it will work its way in), more so concerns when I am cleaning. I have a water filter at my dwelling and I use the filtered water and a microfiber cloth to clean the screen, aluminum base, trackpad, and keys. This is not really the point, but please inform me if my method isn't good, if you would be so kind. My concern is when cleaning the keys, although using a very, very barely damp microfiber and a gentle brushing method, I fear that some liquid may get in between the keys. I realize that if using such and this does in fact happen, the water that gets in there will be less than microscopic, but I'm wondering if I should be concerned with how sensitive something like that is to liquid. I think this is just over-exaggeration if anything but if someone has experienced this or heard about something like this happening, any information provided would be appreciated. Also, there is a moderate amount of ish suspected to be under my keys. What can I use to get this out - and there is a way to get rid of possible dust build-up within the machine, if any exists? I'm sure it does on account of the air vents. I know that everyone will suggest canned air for these two points, but I really don't know about that stuff. It's like ice when you spray it and I feel like that would mess with my machine. Not true? This is all most likely paranoia but I am just trying to be sure that I am taking as much care of my laptop as I can be! Thank you to anyone that offers any helpful information.
