Why is there white residue on my glassware?

This white residue is most likely a result of the hardness of the water. The Moderately Hard to Hard water found in Castle Rock contains naturally occurring calcium and magnesium ions. These minerals are not removed from the water and are actually essential minerals our bodies need. The white spots on glassware or other fixtures are caused by the calcium.  Adding a rinse aid to the dishwasher may help eliminate the white film and appliance discoloration.
