Does Vinegar Kill Mold in Coffee Maker

2025-09-16

Yes, vinegar can kill mold in a coffee maker. White distilled vinegar is a natural cleaning agent with acetic acid, which helps eliminate mold, bacteria, and mineral buildup. Since coffee makers are warm, moist environments, they can harbor mold if not cleaned regularly. Using vinegar is one of the most effective and affordable ways to disinfect them. 

How Vinegar Works Against Mold

  • Acidity: The acetic acid in vinegar breaks down mold spores and prevents regrowth.

  • Disinfectant Action: Kills up to 82% of mold species commonly found in household appliances.

  • Residue Removal: Helps dissolve oils, mineral deposits, and biofilm inside the machine.


How to Use Vinegar to Kill Mold in a Coffee Maker

  1. Prepare Solution

    • Mix equal parts white vinegar and water.

    • For heavy mold, use full-strength vinegar.

  2. Run a Brew Cycle

    • Pour the solution into the reservoir.

    • Start a brew cycle halfway, then turn off and let it sit for 30 minutes.

    • This soaking time helps vinegar kill mold spores inside.

  3. Complete the Cycle

    • Resume the brewing process and let the mixture run through completely.

  4. Rinse Thoroughly

    • Run 2–3 full cycles of clean water to flush out any vinegar smell or taste.


Tips for Preventing Mold in Coffee Makers

  • Daily: Empty leftover water after brewing.

  • Weekly: Wash carafe and filter basket with hot soapy water.

  • Monthly: Deep clean with vinegar or other descaling agents.

  • Proper Storage: Keep lid open after use to let the reservoir dry completely.
