Baking soda and dish soap paste works best for deep stains.

Yes, but it takes elbow grease and patience. Make a thick paste of baking soda and a little dish soap (Dawn or similar). Apply it to the stained area, rub it in gently with a soft brush or your fingers, then let it sit for 15–20 minutes. Rinse with cold water and repeat if needed.

No bleach needed. The abrasiveness of baking soda lifts the stain physically, and the dish soap cuts through oils. For really stubborn marks, a soak in white vinegar and water (1:3) after scrubbing can help. Sunlight also works as a natural bleach alternative if you leave it damp in the sun.

Just don’t use hot water—it can set some stains. And if the stain is from ink or dye, you might be out of luck. White mousepads are not a lifetime commitment.
