1994 Hyundai Elantra getting started with OBD

Computer problem
1994 Hyundai Elantra 4 cyl Two Wheel Drive Automatic

Hi there, I'm sorry for posting this question as a "car repair question" but I couldn't find another more general section.
I've just started getting started repairing my Hyundai Elantra, and in order to do that, I take my laptop near the car (over a table) but you know, as I start getting down to work, my hands get dirty quickly and often, and since I'm new to this, I have to go back to my laptop and take a look at the manuals (pdf), troubleshootings or terms definitions over the internet, so I have to wash my hands every 5 minutes. That's kind of annoying and impractical. I'm sure I'm not the 1st having this problem, so I'm asking for suggestions about what the best rugged bag/cover for keyboard/touchpad haha whatever the best option is, so I can work with my "dirty hands" without worrying about my laptop.

Thank you and merry Christmas!
