Put Vinegar in Your Dishwasher. Here’s Why (And Why Technicians Rarely Mention It)
Your dishwasher may look clean on the inside, but over time it quietly builds up limescale, grease, soap residue, and odors—especially if you live in a hard-water area. What many people don’t realize is that one simple kitchen staple can help solve all of that: white vinegar.
It’s cheap, natural, and surprisingly effective. And while appliance technicians don’t usually advertise this trick, homeowners who use it swear by the results.
What Vinegar Does Inside Your Dishwasher
1. Removes Limescale and Mineral Buildup
Hard water leaves behind calcium and magnesium deposits that clog spray arms and coat internal parts. Vinegar’s mild acidity dissolves these minerals naturally, improving performance.
2. Eliminates Grease and Soap Residue
Detergent residue and grease slowly coat the inside of your dishwasher. Vinegar breaks this film down, leaving surfaces clean and fresh.
3. Neutralizes Bad Odors
That musty or sour smell? Vinegar neutralizes odor-causing bacteria instead of masking them.
4. Improves Cleaning Performance
A cleaner dishwasher sprays water more efficiently—meaning cleaner dishes, clearer glasses, and fewer water spots.
