I got my dads hand me down a few months ago. We put a new head on and I was happy. Well, I decided to see what was underneath the screw on head... oh my god. I nearly threw up. it was black. I had no idea this happens, and I'm very disgusted. I cleaned it out using really really hot water and q tips and shaking it around under the hot water. I can't believe what came out.
Does this happen to all of them?
Is there any way to keep them clean without having to wash it out every day?
I feel so nasty thinking that I put something that was connected to that into my mouth, twice a day, for the last few months....
