At what stages of Ick will cleaner shrimp clean?

Sorry didn't know where to post this question. I have one cleaner shrimp, and I never see him cleaning my fish. As I can see none of my fish have ick now, but should they get it will my shrimp start to eat the ick? Or maybe will he just stick to the regular fish food he finds? Just wondering.

Thanks, I just thought my cleaner was weird, probably no one has wanted his services.

Some fish will look for help from shrimp others such as my Royal Gramma will have nothing to do with them. Luckily they seem happy to eat leftover food so they seldom starve to death.
