I do believe in keeping benches clear after a job is completed. Its good policy.
Otherwise the mess grows over time. And the last thing I need is a scratch on a customers equipment because a nut or bolt got left on the surface. Never mind copper wire strands or solder shorting tracks on a pcb under test.. Nightmare. So, its a clean bench policy for me, after every job, i brush it down an quickly put hand tools away ready for the next job.
Its nice, starting a job with a clean bench.
Or, it could just be my slight case of OCD..
