OxiClean gets sweat stains out of white mousepads.

Soak it in OxiClean and warm water for an hour, then rinse. That’s it.

Bleach is risky—it can yellow white fabrics over time or damage the printed surface. Hydrogen peroxide works too, but OxiClean (sodium percarbonate) is gentler and lifts oil and sweat without scrubbing. For a really nasty spot, make a paste of OxiClean and water, rub it in, let it sit 15 minutes, then soak.

Rinse thoroughly and blot dry with a towel. Don’t wring or scrub aggressively—you’ll ruin the cloth or the adhesive backing. Air dry flat.

Test a tiny corner first if you’re nervous. Future You will thank Present You for not turning it into a tie-dye project.
