If you have a home with dishwasher, it probably save you loads of time on hand-washing. But dishwashers, as quick and thorough as they are, can also wreak havoc on your kitchenware when they’re not used thoughtfully. That said, there’s one simple thing you should do before you start it: Shake both racks to make sure nothing can jiggle around and break. This is key, whether you’re running either a partial or a very full load. If stuff has room to jiggle around, it will definitely jiggle around once the water starts streaming in. And then you run the risk of things breaking or getting damaged. Just give the racks a shake. If things shift around or bump into each other, you’ll need to rearrange some pieces or even take some things out to hold for the next load or to wash by hand. Yes, it’s a slightly delicate balancing act, but checking off this step is sure to be less annoying than cleaning out broken glass from your dishwasher.
