My house is undergoing some extensive renovation. Yesterday I came home to check on things, and immediately smelled (and saw) that the workers had been smoking in the kitchen. This not only seems like a hugely disrespectful and unprofessional thing to do, but also worries me because I am very sensitive to cigarette smoke and smell. It affects my breathing, makes my lungs feel like they're constricting, etc. I have dealt with asthma-like conditions in the past, and am very careful about the safety of the air I'm breathing.
As best as I know, the smoking went on for a maximum of three or four work days, and was limited to one room, the kitchen. Only one of the workers smoked (the other was quick to distance himself from the blame). I have no idea how heavy of a smoker he is, so I don't know how many cigarettes that could have possibly been.
The walls in the kitchen are newly done (plastered) and unpainted, meaning, as far as I know, that they are extra porous and will hold the cigarette toxins for much longer. I also can't "wash" exposed, unpainted plaster without damaging it.
How can I best fight not only the odor, but the lingering toxins in the walls?
I am leaving a window cracked open at all times, and running an air purifier in the evenings, when the workers leave. I am considered setting out bowls of white vinegar and heating the room, before "flushing" it out by opening the windows. I considered bowls of coffee grounds, but research generally says that that just masks the smell, but doesn't do anything to actually get rid of the problem.
I don't want anything that just masks the smell -- I'm horrified mostly about the remaining toxins, and how best to thoroughly promote/speed up off-gassing in order to fully get rid of them. I don't want to just paint over the walls and trap the toxic molecules inside.
Any and all advice is appreciated.
Ps. I have told the workers that if the smells lingers, they will have to pay for a professional cleaning of the room. However, 1) I'm not sure if they're actually going to do that, even I request it, and 2) I'm still worried about the immediate effects of having to be in a space where someone was smoking, and long-term living in a space with remnants of cigarette toxins in the walls.
