No, but in the midst of war, polishing the chrome on your ship is the least of your worries. For Lando, it was another thing. He is a businessman, and getting people to invest in your company or buy your product is all about presentation. That's why Bespin was so clean by comparison. It's for show and for the sake of "first impressions." He's not directly fighting in the war although he is affected by it.

This is why the ships are no longer clean in Ep III as opposed to Eps I and II. In those, the war hadn't really begun in full scale yet. Ships are clean. Now you're in a war and you are fighting and your only concern is the maintenance of the ships to make sure they work. Beauty takes a backseat to functionality.

Do you really think the soldiers in Iraq are polishing the chrome on their Humvees?
