How to clean out ice maker trays

How to clean out ice maker trays After 6 months of trying to figure out the problem I finally caught the icemaker in the act! It turned and dumped partial pieces of ice cubes. When it turned back and filled I reached into the tray and felt partial pieces of ice cubes thereby causing the ice tray to overfill and drip down into the bucket freezing the collected ice and making a solid block. Any ideas as to how to demineralize the ice tray so all of the cubes drop? It's been so frustrating!
