I spent the best part of a shift yeterday cleaning the cocpit of the aircraft I am currently working on. The aircraft is in Heavy maintenance for one of the more in depth checks we carry out. Here is the process I went through
-Remove all debris... crumbs, skin flakes, dust from around the instrument panels
-scrub all the ground in crap off all control knobs and switches with a stiff bristled brush and mild soap.
-scrub all the coffee spills and human finger oils off the control panels with mild detregent.
If this cocpit doesnt impress the flight crew... then I think nothing short of a brand new aircraft will!
(Customer aircraft.... we have to keep them comming back for more ;-)
