What Coca Cola Can Do For Your Showerhead
By JACQUELINE DELIBES

With a pH of 2.4, Coca-Cola is just as acidic as lime juice or vinegar, which have a pH of 2. This makes it just as effective in descaling hard water stains on your showerhead.

To do so, unscrew your showerhead, place it in a bag, and pour Coke on it. Close the bag with rubber bands and let it soak for an hour before cleaning it with a toothbrush.
Dirt and grime buildup in the showerhead
Use the toothbrush to loosen debris around nozzle holes and the collar. Once clean, rinse the showerhead off, reattach it, then run the shower for a moment to remove leftover soda.

For fixed showerheads, place your soda-filled freezer bag around the showerhead, secure it with multiple rubber bands around the pipe, and repeat the process.
