Kaboom Bathroom Cleaner for Nicotine on Walls

I have tried most of the solutions posted on different websites, and none have worked. I was convinced that I would have to use a stain blocker and then repaint the whole room. Then, while cleaning the bathroom with Kaboom foaming bathroom cleaner (the one that starts out purple then changes to white), I wondered if this might work.

I sprayed it on a small section of the wall, waited for it to change color then used a kitchen sponge mop to wipe down the section I had sprayed. Well to my surprise, it worked. Since it's a foam, you don't have to worry about it running down the wall. I then wiped down the wall with a water, dish soap (Dawn), and lemon juice mixture to remove any residue and odor that was left behind. I used two buckets, one with the cleaning mixture and one with just water to rinse out the mop head.

Give it a try, it just might save you the time removing furniture and the expense of the paint.
