What to do when the top ball of the belly barbell becomes old and yellowing?

Question

Is there a way to clean it? I know its not on the surface so rubbing it doesnt help. I think its actually molding inside. Thanks for helping!

Answer 1

It sounds like it is time to buy a new one. Its healthy to change them out ever so often anyway because if not it can get build up with bacteria. Try soaking it in peroxide. That will get the bacteria out of it.
