Showerhead De-Clogger Recipe Clean shower heads that have been clogged with mineral deposits with undiluted white vinegar. Place 1/4 to 1/2 cup vinegar in a plastic food storage bag, and secure the bag to the shower head with a rubber band or twist ties. Let stand for 2 hours to overnight, then rinse and buff the fixture to a shiny finish. Add sparkle to your shower head by spraying with plain baking soda and buffing it with a paper towel when you're done.
