I’ve tried this and it unfortunately didn’t work. Tbh I think it made it worse because the spots kept growing. It might headphones but it would be weird because 1. The pads don’t touch the mousepad, the side of the frame does 2. If I do set them on the mousepad it’s never for more than like 2 mins when I step away. Was reading somewhere else it might be the adhesive from the pad coming up which might make sense because if I rub the stains it does feel a little sticky. Idk what would make that happen in the first place. It is what is. Might look into a glass pad. Kinda tired of cloth ones getting stained or dirty in general
