Dear Queenie,
I never could understand why my wife always used to wash the dishes before she put them in the dishwasher, but after she died and I had to do the dishes myself I could understand better.
Queenie, can you recommend a dishwasher detergent that will really get the dishes clean?—Recent Widower
Dear Widower,
My condolences on the loss of your wife.
If your wife had been using the same dishwasher for many years, the problem may be that it (too) is getting older and older. If all the detergents you have tried are not getting the job done, it probably is time for you to get a new dishwasher.
And even so, it is usually a good idea to rinse the dishes off before putting them in the dishwasher.
