The dishwasher was invented to save you time and make it easier for you to clean your dishes. It really should be quite simple actually. Just load the dishwasher, add some detergent and run a cycle. But for as long as dishwashers have been around there has been a problem with dishes coming out spotty, cloudy or covered in a white film. Many people think they need a rinse agent or even a new dishwasher to solve this problem. The real problem is actually the water that is going into the dishwasher. Almost 90% of the country has some degree of hard water and when that water is heated up in the dishwasher it dries with a white, chalky residue.
Since the recent ban on phosphates in our detergent the hard water problem has gotten even worse. Although the ban on phosphates is good for the environment it is not good for the look of your dishes. It helped clear up some of the hard water residue and now that it is banned dishes will look cloudier than ever.
So if you have to hand wash all your dishes after you take them out of the dishwasher you are simply just wasting time.
Possible Solutions:
Rinse agents help when dealing with water spots when drying but cannot clear up hard water residue.
You can rinse your dishwasher with vinegar but that will only help clean the inside and not prevent the problem in the future.
The Dishwasher Filtration System from Difi at www.dishwasherfilter.com is the perfect solution. It filters the hard minerals out of your water before they even enter your dishwasher. Even with the ban on phosphates your dishes with this system will come out spotless every time.
