You can't wash or rub away a shiny spot on a cloth mousepad.

No. That smooth, shiny patch is permanent.

It’s not dirt—it’s the fibers getting compressed and polished flat from your wrist or mouse feet. Washing removes oils but can’t un-flatten the fibers. Rubbing just makes it shinier.

You might get a slight improvement with a stiff brush and detergent, but the texture will never come back. That spot will always feel different.

If it bothers you, buy a new pad. Or flip it if it’s reversible. Otherwise, just live with it—it doesn’t affect tracking as much as you’d think.
