About Kirkland Signature Ultra Fresh
Kirkland Signature Ultra Fresh In-Wash Scent Booster is Costco's private label answer to premium in-wash scent boosters like Downy Unstopables — delivering comparable long-lasting freshness at a significantly lower cost per ounce. The Ultra Fresh formula uses scent booster beads that dissolve in the wash to infuse fabrics with a clean, crisp Fresh fragrance that lasts from the wash cycle through drying, wearing, and storage. At $0.61/oz, it delivers exceptional value compared to Downy Unstopables ($1.00/oz) while providing the same long-lasting scent boost experience. The 45.9 oz (2.87 LB) bulk bottle is ideal for large households and high-volume laundry use. Made in USA. Distributed by Costco Wholesale Corporation.
Frequently Asked Questions
- How does Kirkland Ultra Fresh compare to Downy Unstopables?
- Kirkland Signature Ultra Fresh In-Wash Scent Booster and Downy Unstopables use the same in-wash scent booster bead technology — both go directly into the washer drum before clothes to infuse fabrics with long-lasting fragrance. Kirkland Ultra Fresh delivers comparable fresh scent performance at $0.61/oz vs. Downy Unstopables Fresh at $1.00/oz — a savings of 39% per ounce. The Kirkland Ultra Fresh bottle is also larger (45.9 oz vs. 39.9 oz), providing more loads per purchase.
- Can Kirkland Ultra Fresh be used with any detergent?
- Yes. Kirkland Signature Ultra Fresh In-Wash Scent Booster is compatible with any laundry detergent — liquid, powder, or pac format — and any fabric softener. Simply shake the beads into the cap, add directly to the washer drum before your clothes, then add your regular detergent as usual. The scent booster works independently of your detergent and does not affect cleaning performance. DO NOT put in your liquid dispenser or dryer.
- How long does the Ultra Fresh scent last on clothes?
- Kirkland Signature Ultra Fresh is designed to deliver long-lasting fragrance that lasts from the wash cycle through drying and wearing. The exact duration varies depending on the amount used, fabric type, storage conditions, and individual sensitivity to fragrance. For maximum scent longevity, use a generous amount (more beads = stronger, longer-lasting scent) and store freshly washed clothes in a closed drawer or wardrobe to preserve the fragrance.
