So I was having a problem with standing water after washing dishes in my dishwasher. I'd come to the conclusion that it was clogged up because of how crappy of a job (none) I do pre-washing the dishes.
I thought to myself, "Hmm... what about running a cycle of Drain-o?" and immediately hit myself with a 2x4 for such lunacy. Who wants Drain-o on their dishes for eternity? Not this guy, that's for sure.
So I went to my pantry and looked at what solutions I had that would be dishwasher-safe. The first thing that caught my eye was a 20 oz bottle of white vinegar (why I had it, I will never know), so I dumped about half the bottle into the standing water and ran a normal cycle sans dishes. Well let me just tell you it worked like a charm and I have been clog-free since.
White vinegar folks, git you some.
