Learn how to use a laundry scent booster correctly for fresh-smelling clothes that last. Get dosage tips, common mistakes to avoid, and why pairing with compatible detergent boosts fragrance.

Quick answer

Add the scent booster directly into the washing machine drum before adding clothes, then run a standard cycle with your usual detergent. For best results, pair it with a matching or complementary laundry detergent.

Why use a scent booster instead of extra detergent

A scent booster is designed to deposit fragrance onto fabrics during the rinse and spin cycles, not to clean clothes. Adding more detergent won't give you lasting scent—it can leave residue and cause buildup. A dedicated booster works in the final rinse to lock in a garden-inspired fragrance that can last for weeks, even in storage.

Scent booster vs. fabric softener: what you need to know

Fabric softener coats fibers to reduce static and soften feel, but it can also reduce absorbency and trap odors over time. A scent booster adds fragrance without coating fibers, so towels stay absorbent and activewear breathes. If you prefer a natural approach and want your laundry to smell fresh without compromising performance, a booster is the better choice.

How to use scent booster for best results

1. Measure the right amount: Check the product label for the recommended dosage—typically one scoop for a standard load. Using too much can leave a powdery residue on dark clothes; using too little won't give lasting fragrance. Start with the suggested amount and adjust based on load size. For a medium load, use one full scoop. For a large or heavily soiled load, you can add a second scoop.
2. Add booster to the drum first: Sprinkle the booster directly into the empty washing machine drum before adding clothes. Do not put it in the detergent drawer or softener compartment—it needs to dissolve in the wash water early to distribute evenly. A common mistake is adding it to the dispenser, where it may not dissolve fully and can clog the machine.
3. Add clothes and detergent: Place your laundry on top of the booster, then add your usual laundry detergent to the dispenser or drum as directed. Use a compatible detergent—like a garden-inspired or natural formula—to boost the fragrance without conflicting scents. Pairing with a strong-scented detergent can overpower the booster's fragrance, so choose a mild or matching scent.
4. Run a standard wash cycle: Select a normal or heavy-duty cycle with warm or cold water. Hot water can cause the booster to dissolve too quickly, reducing its effectiveness. Ensure the cycle includes a proper rinse and spin to remove any excess powder. Avoid quick-wash or delicate cycles—they may not have enough water or time for the booster to fully dissolve and distribute.
5. Dry as usual and enjoy lasting freshness: After washing, dry your clothes as normal—line drying or machine drying. The scent booster's fragrance is designed to last through drying and storage, so you'll notice the fresh smell even weeks later when you pull out that item. If you use dryer sheets or fabric softener, their fragrance may compete with the booster. For maximum scent longevity, skip additional fragrances in the dryer.
