You can sprinkle baking soda over affected area, and vaccum the next day,may need to repeat.Also try placing fresh coffee grounds in a cup, about a half cup, and place cup in the room. And leave the cup in the room for a few days, the coffee grounds will absorb the odor's and the room will smell slightly like a coffee shop. This method should reduce or elimanate the odor.If the results are not satisfactorty, carpet cleaning co.'s have masking chemical's that might resolve the issue, along with charge, quess a fifty dollar minimum charge. Good luck,hope this advice solves the issue.
