Query: OK ball, horrible odor!

The ball works OK, but it has a horrible, absolutely horrible odor. It has a very strong chemicals+BO smell and I can smell if from the other side of my bedroom. I'm trying to replace it with my office chair, but I really can't stand the small. I washed it soap in the shower, which made it slightly better, but not quite useable yet. I will leave it in the basement for the next few days and see if it goes away. Also, there are lots of scratches and peeled-off patches on the surface, and I wonder if someday it will pop.
