There would be nothing left of the Ducati if you jet washed it then sent it off on the salty seasBe in rotterdam waiting on papers
When I considered Aus a few years ago you had to have the bikes scrupulously clean for entry, it was suggested the best way was to get a crate from an importer to package up but as long as the whole thing is jet washed with no dirt in tyres etc. that side is OK
