This question already has an answer here:

I have a large airplane build that I haven't touched in quite a while, and it has built up quite a large amount of dust. I've tried using a wet washcloth to wipe off the dust, but when cleaning that way I can accidentally break off large chunks of the build. So, how can I clean off dust in the most efficient way?
