Neither will ethanol (which is what meths is made of - not

Chlorinated solvents will to some extent (as you suggested), but PP
is really very difficult to dissolve. Hexane will soften it, which
may help in removing it.

I have just a look in a couple of old text books. Apparently hot
toluene or other non-polar solvents will work with extend exposure
(IIRC petrol is fairly not polar) I don't think you will be able to get
hold of toluene or hexane (both quite nasty).


Forget it - you will not get polypropylene off with solvents, for
mundane purposes it's inert.

Why not just light the fire, scrape off as much as you can when it
starts to melt, and let the rest burn off? It's not hard to ignite once
it's warm.

To cover the mark, you could do what great-grandma did and blacklead the
stove. I wouldn't bother until the cold weather's over, but YMMV.
