Machine washing your extended mousepad is a gamble on delamination.

Probably, and the risk goes up with heat, spin, and cheap build. The rubber base and fabric top are glued together, and a washing machine is great at breaking that bond.

The delamination happens when the agitation or heat pulls the layers apart. It’s more common on budget pads where the adhesive is weak. Even on quality ones (like a SteelSeries or Razer), a hot wash and high spin cycle can toast it. Cold water, gentle cycle, no spin? Might survive. But why roll the dice?

Hand wash with mild dish soap, scrub gently, rinse well, and air dry flat. Takes ten minutes, zero risk of ruining a $30–50 pad. If you absolutely must machine wash, put it in a pillowcase or delicates bag, cold water, no spin, no dryer.

Your mouse pad is not a towel. Treat it like a hat you don’t want to shrink.
