Wow - someone who likes a clean cockpit, is borred on long flights and finds something usefull to widdle his time! Something new everyday...
I for one just carry a small brush in my bag - and borrow the vacuum cleaner on the turn-arounds... that is - if you have any

Mind it - just be carefull - powerfull vacuum cleaners have a tendency to sometimes clean buttons as well
Oh - and if you are on my side of the pond and have a spare moment - my room would need some vacuuming too!

(I have a tendency to clean up the workplace, but mess up my home)
Oh - found a link for you - maybe one of those?
