Cleaning Silicone Kitchenware? - silicone kitchenware

Hello to all!

I bought some silicone trays Ice Cube. I ran across dishwashser a few times, but apparently still leave white residue on the glass platelets. What's the deal? I chose silicone cups, because our dear maintained cracks in the plastic. Any tips?

Thank you!
