I have a LEGO Deathstar and have already built stage one of four. However, I haven't been able to get to it lately and it has become rather dusty. How should I clean it? And I travel a lot, so is there any way I can carry it with me by flight without dismantling it?
Which Death Star?
Either way, I can't imagine trying to travel with either Death Star model that LEGO has produced.
Removing dust can be done with a mini-vacuum or some sort of blower, like a hair drier. Canned air is advised against as it has icky propellants that get on your bricks.
