Grab that bottle of white vinegar from the back of your cabinet. White vinegar is a mild acid that absolutely loves to break down calcium deposits. It’s like kryptonite for hard water stains—but way safer and cheaper.
For a faucet or showerhead, just soak a rag in vinegar and wrap it around the buildup. Let it sit for at least 30 minutes. You can literally watch the gunk soften. Then, scrub with an old toothbrush—it’s oddly satisfying.
Got a kettle or coffee pot? Fill it halfway with equal parts water and vinegar, then boil it. Let it soak overnight, and in the morning, pour out a disgustingly satisfying sludge. Rinse twice, and you’re done. Pro tip: Your kitchen will smell like a salad dressing factory, but that smell means it’s working.
Lemon Juice: The Zesty Warrior
If vinegar’s scent makes you wince, try lemon juice. It’s just as acidic but smells like sunshine in a bottle. Plus, it doubles as a natural bleach—great for whitening grout or old stains on porcelain.
Cut a lemon in half, dip the flesh in salt, and rub it directly on the buildup. The salt acts like a gentle scrub, while the acid does the heavy lifting. It’s basically a spa day for your sink. Rinse with warm water, and you’ll wonder if you accidentally bought a new faucet.
How to Remove Hard Water Buildup From Faucets and Showerheads
For glass shower doors, mix lemon juice with a splash of water in a spray bottle. Spritz it on, let it sit for 15 minutes, then wipe with a microfiber cloth. You’ll see streak-free sparkle that makes you want to take a slow-motion shower montage.
