Toothbrush Sanitizer Diagram My Sonicare Electric Toothbrush Smells Strange?

My Sonicare electric toothbrush smells strange? - toothbrush sanitizer diagram

The current treatment feels hurt a little. I take it and clean it every week, say for the directions. I can also brush head more often than necessary (the brush itself does not smell).

Has anyone else this problem and someone has a solution? I know that I am a UV Sanitizer, but I do not, because I heard that these are really not sure that race can and super (such as hand disinfectants, etc..) So, other suggestions? Thank you!
