Cleaner shrimp and wrasse cant "eat" the ich off fish IMHO. once ich has chosen a fish as host, it is not visible. The parasite is microscopic. What you see on the fish is a cyst the fish's body forms to isolate parasite from body. Once parasite matures it drops to substrate and the cycle begins.
They do however do a great job eliminating many other types of stray parasite that happens to enter water column.
