Film can be caused by a couple of things:
- It could be from a lack of water flow within the dishwasher--go to our Dishwasher Troubleshooting section for more information.
- It also could be from hard water. If you can remove the film with vinegar, it's probably caused by hard water deposits.
- Etching--a corrosion of the glass--can be caused by using too much detergent. A rainbow hue on the glasses is the first sign of etching. Try cutting in half the amount of detergent you use.
