# Your showerhead is spraying bacteria: a $2 fix What you think is clean might actually be threatening your health. - **Source:** [Trendir](https://brifing.si/source/fa0937ee-5bfe-4107-bbbb-30be072b2212) - **Published:** 2026-07-18 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/9c6b2875-2c1b-4049-a9b9-de2e1d790539 ## The hidden danger of showerheads Research shows bacterial colonies form inside showerheads. A University of Colorado study of 656 showerheads found NTM bacteria to be the most common type. These bacteria thrive in warm, moist environments. ## How bacteria spread Shower steam carries bacteria into your respiratory system. The CDC states swallowing these germs is harmless but inhaling them may pose risks. This is particularly dangerous for immunocompromised individuals. ## Who's at risk? People over 50, infants under 6 months, smokers, and those with chronic lung conditions face higher risks. Immunocompromised individuals are advised to clean showerheads regularly. ## New showerheads aren't the solution Bacteria actually live in water pipes, not the showerhead itself. Buying a new unit doesn't solve the problem as the source remains. Mineral deposits create ideal surfaces for bacterial growth. ## The $2 miracle solution White vinegar is CDC's recommended method for showerhead cleaning. Its acidic nature dissolves mineral buildup, eliminating bacterial attachment surfaces. ## Cleaning instructions Fill a plastic bag halfway with white vinegar and soak your showerhead for 6-12 hours. Rinse thoroughly in the morning. This process will also improve your water pressure. ## Regular maintenance matters Showerhead cleaning is crucial, especially for vulnerable groups. This simple, inexpensive method protects your health while improving shower performance. The CDC recommends cleaning every 3 months. ## Sources covering this story - https://www.trendir.com/most-people-dont-know-their-shower-is-spraying-bacteria-dont-buy-a-new-one-a-2-fix-works-instead/ — --- _Summary written by Brifing from the original reporting.
