Quick tip for removing Chillz Blox ice cubes: After you twist the tray, use your finger to push the ice cube out of the mold by pushing from the bottom of the tray. The cubes should pop out easily and they are a great presentation in any beverage!
If you suffer from hard-water, this can leave spots on your silicone products after dishwashing. We have this problem and have to hand-wash ours then immediately hand-dry them to remove any remaining water. If that didn't remove the spots, try soaking the item in a solution of half white vinegar and half hot water for about a half hour. Then hand wash and immediately hand dry. Hope this helps, if it applies to you.
