How do you get cigarette smell out of rubber?

Answer 1

Submerging the piece in undiluted white vinegar will help rid an rubber or plastic item of the smoke smell. Leave submerged for however long removes the smell then rinse and dry. Any vinegar smell will disperse in a matter of minutes/hour.

Or you can try submerging in baking powder which will draw the smokey smell.

Finally, even leaving in a freezer overnight can also reduce the smell.
