Glasses look awful after being washed, maybe I need maintanance

If you have hard water glasses can look spotted and cloudy even after cleaning. Sometimes changing the dishwasher detergent can help. The easiest solution to clearing up glasses that start to look cloudy is to add some vinegar to the bottom of the dishwasher before you start a cycle. Simply add 1/4 of white vinegar and it will clear up your glasses very well.
You should see marked improvement after the first time you do this. If they are not crystal clear then simply repeat the process until all of the cloudiness is gone. After that it is recommended to use a little vinegar in each cycle to maintain the clarity of the glass.
