The concept behind the magnets is painfully simple: Display the magnet on your dishwasher, and flip the magnet to the “clean” side when the dishes are clean, and the “dirty” side when the dishes are dirty. While you might be tempted to DIY this hack, these magnets come with an adhesive metal plate to keep your magnet secure because apparently, not all dishwashers are magnetic friendly. They’re also made of durable PVC material and a high-gloss polish that won’t damage your dishwasher. Plus, they’re on sale for just $7, so save yourself the project that many customers noted they have tried and failed. To buy: $7 (was $10); amazon.com. Another happy parent says: “If you have teenagers or just sink monsters that don’t know when to empty the dishwasher, this works great. Really, there are no more excuses around here for not putting your dishes where they belong. I’m so glad such a little thing made such a big difference in our household.” Kid-free households will also benefit from the tool that customers say has “saved them countless arguments.” Available in seven different prints and fonts, grab one of these $7 magnets now.
