OK, here is a bizarre technique that iI learned way back,when I was in
high school, and I was working in a body shop.
We had just repaired a 61 Caddy, and it had  some electrical fire
damage, and it stunk to high heaven!
The boss sent me to an apple orchard, and I was to buy, two bushel's of
apples.
When I got back to the shop, I was instructed to place the apples all
over the inside of the car, and close the doors.
Those apples were left in there for 1 week, and they shriveled up to
nothing.
I then was told to remove them, and the inside of the car didn't smell
like there was ever a fire in there! It seems that the apples absorbed
all the smoke smell!
It smelled like apples, and the customer was ecstatic!
Sounds weird, but it works!

Later,
