I am not among those who use a dishwasher. I am used to hand washing my dishes, not in running water but in water held in two large containers after the soaping/scrubbing session(psst…frankly, I do not even know the technique and the optimal dish washer loading patterns…lol). I wrote about my dish washer dilemma >here
I can very well understand if you are among the dishwasher users. I found this article taking about how pre rinsing doesn’t help. Do read through and may be it will save time, energy and resources.
