There is a product in Canada called "Air sponge" You can get it at the grocery store or Walmart! Comes in tub like margarine.....You'll probably need 4 or 5, depending on the size of your room..... It is a combination of charcoal and pine I think...it does not put a smell in...it only eats odours!! I rented a house one year ( when our house was being built.) It came with a separate guest house that was used by the adult daughter. Shbe smoked a lot and partied I'm sure as there was more than one kind of smoke in there!!! We had to get the smell out as we wanted to store our furniture in there....now granted it was into everything....walls rugs everything but with lots of open windows and fabreze...and the main thing ..the air sponge..... we got it smell free enough to store our stuff there!!! I have used it in old trunks and lots more !! Works!!!
