how do the lungs get rid of solid stuff I inhale? (like dusts for instance)

The cells in the linings of the trachea and the bronchi have very small hairs called cilia. Furthermore, there are goblet cells in the lining which produce mucus. All the stuff that gets into the lungs gets trapped in the mucus. The cilia then move the mucus up to your throat where you then swallow it or spit it out. The carrying of the mucus to your stomach is a process which is happening all the time without you knowing.
