How To Remove Hard Water Buildup From Glass Pebbles?
8 Answers
I put some glass pebbles in my desk fountain, but eventually they turn white from what I guess is hard water buildup. What's a good way to remove the buildup? I've tried dunking them in water and vinegar, but it just shows back up after letting them sit for a few minutes!

Are you sure that the shiny,smooth surface of the pebbles is actually coated with carbonate deposit? Will it scrape off with a penknife blade? I think that the surface of the pebbles may have eroded slightly.... which would make them milky- looking.
