While you can't wash the earbuds themselves, you can clean the silicone ear tips -- just pop them off, rinse, dry thoroughly, and pop them back on. (While the ear tips are off, it might be wise to take a dry cloth to the speaker area, too.)
I bought three sets the last time round: Marley (with the green ear tips), Bliss, and the orange City Lights. Of the three, I preferred the Bliss. I have tiny ear canals as well and even the smallest ear tips on the other two were snug and uncomfortable and prone to sliding out, but the smallest size on the Bliss (x-small) fit like a dream and I can forget they're in, and they stay in place regardless of what I do. Plus the sounds quality is fantastic for a pair of $5 earbuds. (Surprisingly, the bass also kicks.)
In fact, just bought three more of them--one to give away and two as backup. The only thing I don't like is the design of the jack area which is too long and rigid and could easily snag (and I could definitely see it breaking). That area is much better designed on the Marley earbuds--instead of going straight down it curves to one side and has a lower profile.
The controls on the Marley will adjust volume, but the Bliss only mute/unmute/accept calls.
EDIT: obviously I need a nap because I only just now realized that cleaning question was purely rhetorical. :facepalm:
