I work in a timber yard and my 12th gen Framework accompanies me there. There is a lot of saw dust around. I am ready to open it up and tidy the thing.
Is there a guide I can follow about what is/isn’t worth doing in this regard? Ought I fully remove the keyboard, for example?
I have air duster, 80% alcohol hand sanitiser and some contact cleaner. I am fairly patient and not completely terrified of electronic stuff.
Cheers
Thanks very much for the thoughtful response. ‘Air duster’ is a marketing term here for a can of compressed gas you spray in tight spaces with a little plastic tube. I will try the paint brush that’s a great idea. Popping the input cover following those guides seems straightforward enough 
I hope I find what you did – a nice clean interior! Cheers
It would be a good idea to jam the little straw in the fan blades and blast the dust out. BUT - if you do this, be sure to jam something against the fan blades to keep them from spinning. It’s a little comical to spin the fan blades up this way but you can exceed the maximum speed the bearing can take and you may damage the bearing.
Awesome, will do that 
blast the fan… but no spin.
