Put vinegar in your dishwasher. Here’s why. This is something technicians will never tell you (Page 2 ) | November 1, 2025

1. The Secret Cleaning Power of Vinegar
Vinegar is renowned for its ability to cut through grease and grime, making it an ideal cleaning agent for dishwashers. Its acidic nature allows it to dissolve mineral deposits, soap scum, and food particles that can accumulate over time. By adding one cup of vinegar to the bottom of your dishwasher and running a hot water cycle, you can effectively clean the interior of the appliance.
Moreover, vinegar’s natural deodorizing properties help eliminate unpleasant odors that may linger in your dishwasher. This is particularly beneficial after washing dishes with strong-smelling foods. A simple vinegar rinse can leave your dishwasher smelling fresh and clean.
2. How Vinegar Enhances Dishwasher Performance
Using vinegar in your dishwasher not only cleans the appliance but also enhances its performance. Over time, mineral deposits from hard water can clog the spray arms and filters, reducing the efficiency of your dishwasher. By running a vinegar cycle once a month, you can prevent these buildups, ensuring that water flows freely and dishes come out sparkling clean.
Additionally, vinegar can help improve the drying performance of your dishwasher. By breaking down residue and preventing water spots, vinegar ensures that your dishes are not only clean but also dry and ready to use straight from the dishwasher.
3. The Science Behind Vinegar’s Effectiveness
The effectiveness of vinegar as a cleaning agent can be attributed to its acetic acid content, which typically ranges from 4% to 8% in white distilled vinegar. This acid is strong enough to dissolve mineral deposits and organic material without being corrosive to the dishwasher’s components.
