For the last week there's been a strong smell of Boot polish..or even possibly new paint, emanating from my husband\s office. despite me opening windows there all day the smell isn't going away. I accused my husband of causing the smell because he smokes an electronic cigarette , he refutes this..but he has literally very little sense of smell so he can't smell it himself...and he feels I'm exaggerating when I say that I can hardly breathe in that room for the smell. 3 days ago he stopped smoking his leccy cig in that room, to see if the smell would dissipate ..again I've kept the windows wide open, and even used air fresheners ..and instead of lessening, the strong smell is becoming worse.. I can smell it all the way downstairs, and even in the livingroom, although it's obvious it's coming from his office.. he doesn't use shoe polish in there, and there's been no new painting, or use of paint thinners etc in the house...so something must be causing this, and I'm getting a little concerned ...anyone any ideas?
