Essential oils work wonders...1little flask can last years...litterally.
Pepermint works well (smells very sweet and people think that you were sucking on a mint and not spraying away smell) but you can use musk, rose etc...just put a drop on a tissue or piece of tp...it will keep the air fresh for hours...put a drop on a hand towel when you walk in...or get a purse-size empty perfume spray bottle and mix it with water or alcohol to make your own spray.
