All I can say is yes, in my case any way ;)
I use Audiclean on my ears regularly and also my daughter. My boy has very long, hairy, sweaty, waxy ears that I do pluck, but he still gets the itches and the smell. I started using it last year on him and it has dramatically improved. No more itching and the ear canal is clean, pink and sweet smelling. It does say on the bottle "for babies from 6 months" if it is gentle enough to use on babies, then.........:)
Think of it this way, does your dog go in the sea? Mine does, and they get sea water in their ears, in my experience, it has never done any harm, apart from the shaking of very wet head and ears that is :P The sea is not very clean, but in most cases has no damaging effects, so sterile salt water can't be any worse.
