The Dish on Spotty Dishes, Rinse Aids, and Hard Water
What is dish washer rinse aid, and why do you need it? Or do you?
Despite its name, rinse aid actually doesn't have anything to do with rinsing your dishes. Instead, it helps remove water from flatware, plates, bowls, and glasses. Really, it's more of a drying aid. Why don't they call it "Dry Aid?" We don't know, but it would have been a lot more accurate.
Rinse aids contain chemicals called surfactants which lower the surface tension of water. So instead of forming droplets, the water spreads into thinner sheets that roll right off your dishes. If you’ve ever used Rain-X on your car’s windshield, you'll have a good idea of what this looks like. Ultimately, this means that your dishes will dry much more quickly.
The other perk is that rinse aid's hydrophobic—or water repellent—properties prevent your dried dishes from showing water spots, which are caused by minerals left behind as water evaporates off a surface. In a perfect world, the water in our pipes would be pure and free of minerals, but in the real world even water that isn’t considered “hard” still contains trace amounts of limestone or chalk.
So, what is 'hard water', anyway?
Hard water is water that has high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone and chalk which are largely made up of calcium and magnesium carbonates. If your water isn't particularly hard, you might not have as much of an issue with spotty dishes as a friend who has hard water. Hence the fact that I have customers who say, "I have never used a rinse agent and my dishes come out just fine."

The following can all be possible symptoms of hard water:
Strange stains in sinks, showers, and toilets (brown/reddish)
Excessive soap scum
Clogged shower heads
Difficulty in making a good lather during handwashing/bathing
Difficulty getting laundry truly clean
Skin irritation/aggravation of eczema
Appliances wearing out too soon
Of course, these symptoms are not caused ONLY by hard water, but if a few of them pertain to you, you may have an issue.
Evaluating Rinse Aid Products
The Environmental Working Group grades household products on safety for humans and the environment. Most grocery store brands of rinse aid fail miserably (http://www.ewg.org/guides/subcategories/26-RinseAid).
However, be wary of 'natural' and 'green' websites and blogs telling you to use straight vinegar in your dishwasher’s rinse aid compartment. Yes, it's inexpensive and easy to use. In the long run, however, this might cost you a lot more money than you bargained for! The rinse aid compartments on newer dishwashers have rubber components that aren’t really compatible with the acidity of straight vinegar. Putting vinegar in the dispenser on a regular basis can erode or cause the seal in the dispenser to disintegrate!
