Thank you, Eve, for picking up a three-pack of Downy Rinse & Refresh, Cool Cotton scent. It may help to know this product isn't a traditional fabric softener, but is a low-pH rinse aid that works to remove odors and residues left behind on items you wear and use, like bath towels. These residues if left untreated can build up and lead to odor that can be difficult to remove, even with washing. You can use as much, or as little as you need to 'reset' your laundry, getting it as fresh as possible. It's possible you may notice your laundry will exit the washing machine feeling and smelling its best if you add more product to your washer. If you'd like more help with this, we're here Mondays through Fridays, from 9 AM to 6 PM, EST, and Saturdays and Sundays, from 9 AM to 5:30 PM, EST. Our number is 1 (800) 688-7638.
