We talked earlier about eliminating artificial air fresheners and replacing with a natural air neutralizer, but you still want to be sure to eliminate the causes of any bad odours. This means absolutely no smoking inside the house (or in a connecting garage), avoid cooking foods with strong odours such as garlic, onions, and curry, and keep pets and pet areas clean. By opening the windows for a few minutes daily, regardless of the season, you’ll also help to remove any stale odours that are lingering.
