I am very sensitive to smoke smells, and I don't think you can ever get them out 100%. But washing the walls and ceiling will help - sounds tedious but there you go, the only surface you haven't washed! Also some smoke is embedded in the carpet underpad... you could try baking soda or xeolite powder in the carpet leave it on a while so it works it's way into the fibers and down into the pad, before vacuuming up. Get a few of those bags of xeolite volcanic rocks they are good odor absorbers and place them around the house. You might have to replace the carpet and underpad - I hope you had a very large security deposit! We had a guest stay for a week and he was a smoker he was never allowed to smoke in our house he went outside but as soon as he left, the smell from his clothes and clinging to him was still detectable. I washed everything that could be washed on the allergen cycle, and steamed every hard surface with the steam mop/steamer. I opened all the windows and doors for the entire day, and finally the smell was gone. Good luck!

If I were in your situation, first I would call the landlord and have him/her deal with it. If I owned the house, I would start by getting a black light and using it to see where on the carpeting the dog has urinated. I would also check the corners of the room to see if the dog has been spraying on the walls. You can buy them at Petsmart and Petco. Then I would get a gallon of an enzyme cleaner and apply it heavily onto the rug using a $15 hand pump sprayer Not just a light spray, but to the point of soaking so that it reaches the padding. Then you let it dry - no rinsing. I have always used Nature's Miracle, but there are other brands that people say are better. In the end, new padding and carpet may be necessary. If you go that route, after the padding is removed, apply a sealer to the wood flooring, as the urine may have soaked through.

Musty odor in fireplace after rain...I read something about cleaning logs.should I remove logs when I shut the pilot light off? Should I buy new logs? Or is it the vent?

Use Kilz paint after you wash the walls thoroughly, I would use Nature's Miracle for cleaning everything, the stuff is awesome. Other members may have a cheaper solution than the Nature's Miracle, I swear by it, it removed all the cig smoke from a love seat that was given to me.
