Bob,

We are using a wood stove in our basement to supplement heat
and I have started to notice a "plastic like smell" especially
when I've rekindled a fire and got it going nice and hot.

Anthony, Did you get any answers?

That was an old post from a few years ago, and I don't remember hearing a
reasonable explanation for the plastic smell.

Thankfully, the plastic smell eventually went away on it's own, as
inexplicably as it started.

Anthony
