Gain Aroma Boost 洗衣液 Original 香型 — 107 次洗涤，留香长达 6 周！限时 $15.99 加元（省 20%）

Gain Original Scent is the one that built the brand — a crisp blend of citrus and mountain florals that smells clean without being overpowering. The Aroma Boost formula uses microcapsule technology to lock in freshness for up to 6 weeks from wash to wear, releasing scent gradually as fabric moves throughout the day.

On the cleaning side, Gain's odor-fighting ingredients handle everyday smells like sweat and kitchen grease reliably. The concentrated formula delivers 107 loads from a single 4.55L bottle — at a few washes per week, that's over half a year of laundry. Fully compatible with both regular and HE machines, and effective in cold water.

Ranked #10 in Liquid Laundry Detergent with over 27,000 reviews at 4.8 stars, this is about as safe a household staple pick as you'll find on Amazon. If you're already a Gain fan, pairing it with their fabric softener and scent beads takes the longevity up another notch.
