First things first - fresh-smelling laundry starts with a detergent that cleans away odor-causing residue instead of masking it. That is it - you do not require a paraphernalia of items to achieve clean smelling laundry. If you have to buy scent boosters, you are probably buying the wrong detergent. That said, fragrant mists could enhance the fragrance for the times when you feel the fabric does not need a wash yet.
