Technology Connections’ video on dishwashers will change your life. [VIDEO] Ever since I switched to powdered detergent and started throwing a pinch of powder in the bottom of the tub in addition to filling up the main dispenser halfway, I have not had a single dish come out with a piece of food on it. I also recommend disabling any “auto” features of dishwasher has. The only caveat to this video: don’t fill up the detergent dispenser all the way with powder, go about halfway. He corrects this mistake in his follow-up video, which I also recommend.

I love this video: [VIDEO] Dishwasher pods are heavily marketed in the US and actually wash more poorly compared to plain powder. With pods the pre-wash ends up running without detergent, so rinsing off dishes becomes necessary.
