I have a set of washable bands that I swap out weekly. Cause, ewwwww.
@Cosmichomicide
It wasn't the band. I just installed a new, metal one.
There is a lot of room for "stuff" to collect on the device itself.
Oh yeah - but I clean all my "fingers" electronics at least weekly - phone, keyboard, mouse and Fitbit .
You are clearly a better person than am I.
Do you have a keyboard that is separate from your computer?
OK, so I have 3 keyboards, not including the one I never use on the laptop. Every week they get a superficial cleaning, periodically I pull their little caps off and give them the deep cleaning love and attention they deserve.
My keyboard ritual is the traditional shake, followed by the old school compressed air (though I have a gun for that and not the disposable cans), followed by slime/goo. If anything seems like it's not responsive, I pull the key and clean or replace the switch and/or cap entirely.
And yes, folks need to clean their keyboards just to get an idea of how EWWWWW things can be.
