$$$ saving tip!

While having some things checked at the beach house, the repairman from Del Mar Appliance was a wealth of information. He gave me two tips which made a ton of sense and I thought I would pass them along - just before you run your dishwasher (finally have one back in my kitchen!!) run the kitchen sink until the hot water comes out. That way the water that goes into the dishwasher is hot from the beginning. He said it takes a long time for the dishwasher to heat the water. I tried to find supporting research for this. He also said that you really only need about a teaspoon or two of detergent.
