Just want to mention, that my WB disappeared when I took it OFF!! Easy to pop into the ultrasound or use one of those cute brushes-to-go, but if you're WEARING it you won't lose it. I remember a gal from work put her clothes in a locker for a spa massage, but forgot to take her rings off, so she put them in the robe pocket forgot them and GONE! Same thing happened to me with my Return to Tiffany bracelet at a Ritz Carlton Spa - I wish I'd dealt with cleaning oil off it vs losing it!
