I have visited several residences in the last few days and noticed a strong smell of smoke. People wanted to sell nice expensive furniture and from experience I knew even few charities would take it.
You can wash china and get rid of the stains and smells. You can wash clothes and linens and often get rid of the smell. You can not get rid of the smell in wood or “stuffed” furniture or mattresses.
I hate being the bearer of bad news but if you are hoping to sell furniture that has a smoke smell it is more difficult now than it was a few years ago.
