Washing walls..

I would try a solution of tsp and water, wash the walls down with that then rinse with clean water. If you see streaks, repeat the process

Here are a couple of articles talking about products to use and methods to make sure you use as well to get it all out. If I were you, once the smell is out I would repaint all the walls, as well.

White vinegar and water 50/50

Thank you!!

I used the all purpose cleaner found in the gallon containers in the automotive section. It's usually purple or pink or green. It's very concentrated, so follow directions. Start at the top of a wall --wash, rinse and dry with old towel. Have several sponges, as you'll have to change when they get too dirty. My paint came out looking like new. Need to rinse if you do want to repaint, to remove traces of soap. Sounds like a lot of work but the results are worth it, and the room will smell noticeably better!

My mom ued to tell us to start at bottom of wall and wash up or streaks form and can't be washed away. Murphy's Oil soap is really good natural cleaner, no rinsing required. Smells nice and non toxic.

When I had to clean my mom's heavy-smoker'd walls, ammonia took care of all the deposits. I used straight ammonia (lemon-scented) from the bottle on the worst places. It's cheap and easy. You'll want to make sure and wear protective goggles/gloves and have the windows open for ventilation, but I'm sure you'll be thrilled with the results.
