People...
It's all very good cleaning up the rubbish in the flight deck, which i'm sure most of us do....
It's the crap on the floor thats the problem... dead skin, tiny bits of food, short curly hairs

, spilt coffee that you dont have the equipment to clean up properly, that get stuck in the floor in all those wee places that just attract stuff like that and build up quickly...
I never said it was an engineers job to clean out the rubbish but surely something needs to be done to fix it...???
