Should have. It's actually a solution for softening and removing
ear wax--dunno what it's called though. My dad uses it--you
basically pour the solution into a small plastic cup, tilt your
head sideways so your ear opening covers the cup, straighten your
head with the cup still pressing against your ear, then rock your
head from side to side to allow the solution to enter the ear canal
and flush out the wax.
Don't know if it will help with the itching, though...
