Whether you just purchased a new car from a smoker or you're trying to freshen up your own habit, green living blog Yahoo! Green suggests tossing a layer of used coffee grounds into your car's ashtray to get rid of the scent of cigarettes.
As we've seen before, coffee grounds are a great deodoriser for drains, but they also work remarkably well at removing odour of all kinds, including the smell of tobacco from cars, which is especially handy it you're a non-smoker who has just purchased a used car from someone who smoked in it. You can find a whole collection of other tips for using coffee grounds over at Yahoo! Green.
