If your clothes, towels, or bedding come out of the wash smelling less than fresh, or if stubborn odors like sweat and mildew linger no matter how much detergent you use, a laundry scent booster might be the simple addition you're looking for. Products like ARM & HAMMER Odor Blasters Laundry Scent Booster in Fresh Burst scent are designed to work alongside your regular detergent, targeting odors that standard washing alone may not fully eliminate.

What Is a Laundry Scent Booster, and How Does It Work?

A laundry scent booster is a product made from small scent crystals or beads that dissolve during the wash cycle. Unlike fabric softener, which coats fibers, scent boosters are designed to penetrate fabric and neutralize odors while adding fragrance. They're meant to be added directly to the washing machine before you add your clothes and detergent.

ARM & HAMMER Odor Blasters Fresh Burst comes in a 45 oz container and works in both standard and high-efficiency (HE) machines. The product dissolves in cold water, so you don't need to adjust your washing temperature, and it's safe for all fabric colors and types. The formula uses fresh floral notes to create what the brand calls a "vibrant burst of fragrance" that's meant to last through drying and beyond.

When to Use a Scent Booster in Your Laundry Routine

Scent boosters are particularly useful for specific laundry challenges. If you have gym clothes, activewear, or athletic socks that retain sweat smell even after washing, a scent booster can help. Similarly, if your towels start to smell musty after a few days, or if bedding develops odors between washes, adding a booster to those loads makes sense.

They're also worth considering if someone in your household has particularly stubborn body odor issues, or if you've noticed that your regular detergent alone isn't keeping clothes fresh-smelling for as long as you'd like. Scent boosters are not a replacement for detergent—they work in addition to your regular washing routine.

Common Questions About Using ARM & HAMMER Odor Blasters Fresh Burst

Do I need to use it on every load? No. Use scent boosters only on loads that need extra odor-fighting or fragrance. Many people reserve them for athletic wear, towels, and heavily soiled items rather than everyday clothing.

How much should I add per load? The product label will specify the recommended amount based on your load size and how strong you want the fragrance. Start with the lower recommended amount if you're unsure, as you can always increase it next time.

Will it work in my machine type? ARM & HAMMER Odor Blasters Fresh Burst is formulated for both standard and HE machines, so compatibility isn't usually an issue. Just follow the label instructions for your specific machine.

Is the scent strong? Scent boosters typically deliver noticeable fragrance. If you prefer lightly scented laundry, use less product or skip the booster on sensitive loads. Those with fragrance sensitivities should test on one load first.

Storage and Container Size

The 45 oz size is a standard household container. How long it lasts depends on how frequently you use it and how much you add per load. Keep the container sealed between uses to preserve the scent crystals. The product comes in a recyclable plastic bottle made from 50% recycled materials, so the packaging itself has a lower environmental impact than some alternatives.

Pairing With Other Products

ARM & HAMMER offers a coordinated Fresh Burst line that includes matching dryer sheets and laundry detergent. You don't need to buy all three to use the scent booster effectively—many people successfully use it with any standard detergent they already prefer. However, if you want a completely coordinated fragrance experience from wash to dry, the matching products are available.

Scent boosters are a practical addition to your laundry toolkit if standard detergent isn't keeping your clothes smelling fresh long enough, or if you're dealing with persistent odors that washing alone doesn't solve. ARM & HAMMER Odor Blasters Laundry Scent Booster in Fresh Burst scent offers a straightforward approach: add it to your machine, wash normally, and let the scent crystals do their work.
