Grab a small plastic bag—a sandwich bag works great. Fill it halfway with plain white vinegar. Not the fancy balsamic, okay? Save that for your salad.
Now, tie the bag around your faucet or showerhead so the nozzle is fully submerged in the vinegar. Use a rubber band or a twist tie to hold it in place. Let it soak for at least 30 minutes to an hour. If the buildup is ancient and stubborn, let it sit overnight. Go read a book, pet your cat, or practice your evil laugh—the vinegar is doing all the work.
After the soak, remove the bag and scrub with an old toothbrush. You’ll see the white flakes fall off like snowflakes in reverse. Rinse with water, and you’re done. It’s magic, but it’s real.
