I have a ceramic airstone in a fresh-water aquarium. How can I clean it?

soak it overnight in hydrogen peroxide. Yesterday I was at our local drug
store picking up a prescription and there was a guy buying a 4 liter jug of
isopropyl alcohol. I heard him mention to the person at the counter that he
uses it to clean his airstones on his fish tanks.
