Most Scotch‑Brite sponge heads and refills are made from cellulose or from foam.
Some listings note scrubbing fibers made from 100% recycled content or recycled plastic, and certain items highlight reduced plastic packaging or "recycled scrubbing" claims.
Hold the dishwand with the head facing up, push the tab away from the handle and slide the old refill off. Slide a new head onto the handle until it clicks. For soap‑control/dispensing heads, remove the soap stopper through the back if instructed to enable soap flow.
Many sponges use an S‑wave or S‑shaped profile for a comfortable, secure grip and better reach into tight corners. Some also include scrubbing dots, flexible shapes or textured scrubbing surfaces to help access tricky areas.
Product details repeatedly state these sponges or heads can be sanitized and cleaned in the dishwasher up to 20 times.
Odor Resist uses an antibacterial treatment that helps the sponge resist bacterial odors for up to three weeks of use. Listings also note it does not protect users from food‑borne or disease‑causing bacteria; they recommend rinsing the sponge and allowing it to dry between uses.
