Mucous clearing out of lungs

@kyleb5953 That feeling of junk in the lungs sure can be troublesome. Is this a new issue for you? When figuring out how to manage it, it is helpful to know what underlying issues you have like asthma, allergies, COPD, chronic sinusitis, etc. Each would indicate a different management strategy.
Have you seen a doctor about it?
Mullein can be helpful fot thinning mucus for some people, but doesn't necessarily reduce the quantity. And in some cases, people are actually allergic to it.
What other things have you tried?

@sueinmn I am a smoker, but have no other issues... 40+ years of this nasty habit, and I guess it's catching up with me. This has been going on now for just over a year, and all of a sudden. I know quitting smoking could stop the continuation, but is it possible to get what's been accumulating over the years out of my lungs....?

@kyleb5953 You could try saline nebulizer. It works pretty good at getting the phlegm up. I would consult a doctor to make sure that you don't have any underlying issues other than the fact that you smoke though.

@kyleb5953 Step one - see a doc to have your lungs checked!l Any major change needs to be evaluated to find out if there is a treatable underlying cause.
Have you done this?
Step two, of course is to quit smoking, and not replace it with raping or smokeless tobacco. What have you tried so far?

I know 3 people, 2 of which were heavy smokers for many years who quit after reading Allen Carr's book "The Easy Way to Quit Smoking". He has a very interesting, different approach. Couldn't hurt to try it. If you are not fond of reading, it is also available through seminars or podcasts.
