You don’t need to pre-wash dishes before they go in the sink, beyond a basic scrapping of the plate into the garbage. Pre-washing dishes degrades the performance of the dishwasher. This is due to the use of enzymes in modern detergent formulations. I’ve sent dozens of people the Technology Connections video on this topic to rave reviews: this video
If you have soap residue: - Try running the dishwasher a second time with no soap, or on a rinse cycle - If you use soap pods, try putting it not in the soap tray, but directly in with the dishes. [0] [0] This video (starting at 11:40) explains how soap is used in a dishwasher. This guy (who has an excellent channel) gives tips to maximize soap exposure in your dishwasher, but you can do the opposite to minimize it instead. If you have a good machine, your dishes might still come out clean. this video
Article is wrong. Tablets/pods are silly. The most important thing to improve dishwasher performance is to put detergent in the prewash compartment as well as the main compartment, which you can't do with pods. Second most important (maybe North America-specific) is to run the hot water in the sink to flush the cold water out of the hot water line before starting, so the first fill of the dishwasher uses hot water. More than you ever wanted to know: this video
Hate to be that guy, but I'm not sure this is an HN worthy article to be honest. It's a listsicle that covers the title for a minority of its points. Perhaps one could look at this recent Technology Connections video and its accompanying blog for a more insightful look: this video Alternatively, perhaps a direct link to the video from this article is in order?
> I was minimizing time so spent while she was minimizing number of washes I'm probably just slow, but I'm not following. Do you mean because you went fast, you had to run another cycle to clean everything properly? If you haven't already, you should watch the Technology Connections series on dishwashers. this video
