"Strange but true?" Our home experiment

For the past few months our dishwasher has been deteriorating. It's been leaving more and more particles on the dishes after being washed. We've tried different detergents and that worked for a while. We tried rinse agents and that worked to a point too. Now it's to the point that nothing is working. I've run empty loads to try and flush whatever out. I've run empty loads with vinegar. Nothing. Then our friend told us to try putting Tang in our dishwasher. Huh? I guess the Vitamin C and the acidic value to the Tang helps to flush things out in the pipes. Our friend said it might take 2 or 3 loads for it to work, but he swears by it. Right now as I type the house has a lovely orange space-aged scent to it. I'll keep you updated on if it worked or not.
