OK, so I got the O-Cedar H2prO Flat Mop to wash down the walls. Stop laughing at me, I am not a nut. I have 3 cats for some reason, and I noticed some cat hair up in the corner of the back bedroom. My duster just didn't quite reach it. Then I noticed that nasty cigarette smell. A friend who smokes had just stayed with us. After looking everywhere, I settled on the standby Vinegar and water cleaner. The system worked better than I hoped, and the smell is gone. Toss these pads in the washer and they are good as new.
