Hi Flyaways. Putting aside legalities and wages balanced against hours et al, as Pilot DAR hinted, there are icky jobs and this sounds like one of 'em. That said, I wonder if you are being tested in some way? Y'know, you pull the plug after a few days and you'll have your card marked as someone who couldn't stand the icky jobs to eventually make progress or was simply 'above himself'. The answer to this puzzle is to ask to see if there is definitely going to be light at the end of the tunnel.
Icky jobs will come later too! Pilot DAR's local kids won't get on their backs under the aircraft to clean and you'll get that to that stage too, imagine what it's like in winter lying on wet ashphalt with freezing water running up your arm to your armpit!
Even further, some 'plum' jobs have their fair share of not-so-nice aspects. All part of the world of work I'm afraid! Whatever you choose to do, I and I'm sure others here wish you well.
