What's the purpose of cleaning machinery?

Hi all,

I see that tractors and other stuff get really dirty overtime, and that you can wash them at the fuel station but... what for? I mean, what is the practical gain of cleaning them?

Thanks,
Cluny

I've honestly not seen a reason beyond making them look nice again.

Just for cleaning the dirty machines, nothing else I think.

Ah, OK. So it's just an entertainment, but nothing you really have to do...

Thanks
