How to clean Logitech g430 head piece?

[all1d0isw1n]

Before all of you mention that I can remove the ear cups to wash them, I will tell you now that I know that. I'm asking about the foam piece that goes on the head. How do I get rid of odors on that piece? It's not removable so I don't know how make it smell fresh or neutral.

theres not a lot you can do other than wash it with soapy water and hope it doesnt shrink when drying.
you will need double sided sticky tape to reattach it if you remove it.
