When 'sucking', you have to be careful not to suck up any of those little original labels that often come unstuck from the chassis itself or other components, and go unnoticed into the cleaner. I find when blowing, that I generally spot them flying off and can retrieve them before they blow away and get lost altogether. After the main, more 'distant' blowing out, I then get up closer with the soft paint brush. Unregulated compressed air is really too harsh for delicate cleaning, so an ordinary old vacuum cleaner on blow is the best option if you've got one, or perhaps one of those air pumps as previously mentioned by someone.
