I grew up with eight brothers and two sisters all younger than me, and now I live alone I am just glad that everything is where I last left it dust and all. I only take extreme care with any optical surfaces. A bit of dust, finger print or dew anywhere else can easily be cleaned.
After an all nighter I now put a towel on the OTA's since one morning while making coffee just after dawn there was a very large magpie perched on the 100ED. Yes he did leave his mark!
You should only be fastidious with optical surfaces, the others you should treat in such a way you are happy with. Otherwise you will not really get the benefit of using your gear for what it was designed to do.
