Most products are added directly to the washer drum: pour or toss the beads into the empty drum, add your clothes on top, and run the wash cycle as usual.
In addition to adding scent, several products advertise odor‑control or deodorizing performance (for example, odor‑blocking or odor‑defense technology) to help neutralize unwanted smells in laundry.
Scent intensity is typically adjustable by the amount you use: add a small quantity for a light scent or more for stronger fragrance. Follow the product instructions for recommended amounts.
Many listings state the products are bleach‑free. Some light or 'light scent' formulas explicitly advertise no heavy perfumes, no dyes, and no phosphates. Check individual product labels for exact ingredient claims.
Review summaries indicate several scent boosters are perceived as gentle and suitable for baby laundry or sensitive skin, and some product descriptions specifically target baby use. Always check the product label for baby‑safe or sensitive‑skin wording and consider testing a small item first.
