Lenor Unstoppables is an in-wash scent booster that keeps going where current freshness fades, letting you experience up to 12 weeks of boosted freshness (in storage). That's because Lenor Unstoppables goes in at the beginning of the wash so more scent infuses into the fabric slowly over time. Lenor Unstoppables should be added to you laundry routine before every wash. Throw the scent booster directly into the washing drum. Add your laundry detergent. Add your fabric conditioner for softness.
