You Should Put a Bowl of Vinegar in Your Dishwasher—Here’s Why
White vinegar is the darling of homemade cleaning supplies. From window-washing and mopping to disinfecting the sink and removing soap scum, trusty old vinegar can be counted on again and again. Here’s yet another reason to love it (and to keep it under your kitchen sink). White vinegar can be used as a rinse aid in the dishwasher, especially to combat hard water staining.
Speaking from personal experience, it’s extremely frustrating to run the dishwasher only to open it to dishes that are far from sparkling. Hard water stains leave spots on dishes and can make glasses cloudy. It’s embarrassing to set the table with those, especially when you feel compelled to reassure any guests that “the dishes are clean; it’s just the hard water.”
How to Put Vinegar in Your Dishwasher
Some people put vinegar in the rinse aid compartment, but the vinegar could compromise the integrity of the compartment’s gaskets. To be on the safe side, put the vinegar in a dishwasher-safe bowl on the top rack of your dishwasher. (This also helps the vinegar reach the dishes most affected by hard water marks.)
What a relief—and a simple joy in life that I have learned to appreciate—to pull actually clean-looking dishes out of the dishwasher!
One more tip:
You can also put white vinegar to work to clean your dishwasher itself. The process is quick and simple and involves no scrubbing on your part (yes!).
After cleaning out the drain to remove any crud captured there, run a cycle with a vinegar rinse: Place a cup of white vinegar on the top rack of the dishwasher and set your dishwasher on a hot water cycle. This will clean out any lingering grease or grime that’s clinging to your machine and will also help prevent musty odors from forming.
