1. Spend 2 hours -- in a full sweat -- watching soap suds and water pour out of your dishwasher as you run from laundry room to kitchen with towels, buckets, rags and mops trying to keep up with the mess and maintain your sanity. At which point you will realize you have gotten nowhere.
2. Put 1 tablespoon of fabric softener in your dishwasher, close the lid, and wait for 60 seconds. At which point you will find not a sud in sight. True story.
