6 Reasons Why People Spray WD-40 Up a Faucet

Why People Spray WD-40 Up a Faucet

WD-40, a popular lubricant and penetrating oil, has various uses that extend beyond its original purpose of preventing rust and degrading metal.

One such unconventional application is spraying it up a faucet. But why would anyone do that? Simply put, they do so to address issues like annoying squeaks, hard-to-turn handles, or loosen mineral deposits that may obstruct the water flow. Stay tuned as we delve deeper into these uses.

Preventing and Fixing Faucet Issues

1. Lubricating O-rings and Gaskets

Let me share a little story with you. I remember being pretty stressed about an incessantly leaking faucet in my kitchen.

A friend suggested using WD-40, and voila! It sealed the deal! The O-rings and gaskets inside your faucet can become dry and brittle over time, causing leaks.

A quick spray of WD-40 can lubricate and revive these components, preventing further leaks and adding longevity to your faucet’s performance.

2. Addressing Stiff Handles

I once visited my grandmother and noticed her struggling to turn on the faucet. It was clearly a stiff-handle issue.

Having experience with this, I grabbed my trusty can of WD-40. A little spray in the right places, and the faucet handle was turning smoothly again.

WD-40 is excellent for easing stiff or hard-to-turn handles. It penetrates and loosens any corrosion or mineral build-up that might be causing the stiffness, making it easier for everyone to use the faucet.

3. Quieting Noisy Faucets

There’s nothing quite as disruptive as a noisy faucet, especially if you’re a light sleeper like me. It was during a peaceful night when a dripping sound interrupted my slumber.

It was the bathroom faucet. Remembering my trusty friend, WD-40, I quickly sprayed the noisy culprit. To my relief, the annoying sound vanished.

WD-40 can help quiet noisy faucets by lubricating the components inside the faucet, reducing the friction contributing to those irritating noises.

Dealing with Rust and Corrosion

4. Preventing Rust Buildup

I’ve always believed in the saying, “Prevention is better than cure.” This also applies to our faucets. To prevent rust buildup, I habitually wipe down my faucets with a soft, dry cloth after every use.

Moisture is a chief contributor to rust, so I minimize the chance of rust formation by doing so. Also, I occasionally apply a thin layer of car wax on the metal surface, which is an extra barrier against moisture and, ultimately, rust.

5. Removing Existing Rust

I noticed an unsightly rust stain on my bathroom faucet one fine afternoon. I could have ignored it, but I decided to tackle it head-on.

I used a simple home remedy, mixing equal parts of lemon juice and baking soda to create a paste. I applied the paste to the rusty area and left it for several hours.

After scrubbing gently with an old toothbrush, the rust stain had completely disappeared!

6. Extending Faucet Lifespan

Taking care of our faucets is akin to preserving an investment. I remember my father’s advice about maintaining things to extend their lifespan – advice I apply to my faucets.

I repair any leaks promptly, as continuous water exposure can expedite rust formation and corrosion.

I also avoid over-tightening the faucet handles, which can stress the components and lead to premature wear and tear.

Lastly, I schedule regular check-ups with a professional plumber to ensure my faucets’ internal components are in good shape.

I’ve significantly extended my faucet’s life by taking these preventative measures.


In this journey, we’ve explored a myriad of reasons to use WD-40 on our faucets. From preventative measures to restorative applications, this mighty helper has proven to be a staple in our home maintenance toolkit.

Whether it’s to silence creaky hinges, prevent rust, clean stubborn stains, or even lubricate the faucet’s internal components, WD-40 has stood up to the task splendidly.

I recall a day when a stubborn rusty component threatened to ruin a family gathering, but a quick application of WD-40 saved the day, to the amazement of my guests.

But the utility of WD-40 goes beyond faucets. In my home, it has become an indispensable tool for a variety of tasks. The squeaky door that used to wake up the baby?

A thing of the past, thanks to WD-40. The sticky drawer in the kitchen? Operates like a dream now. It has proven its worth time and again in alleviating common household woes, making it a must-have item in my home.

While WD-40 is indeed a remarkable aid, I’d like to stress the importance of using it responsibly. Always remember to use protective gear like gloves and eye protection, and ensure your work area is well-ventilated.

Keep it out of reach of children and pets, and remember, it’s not a toy. With these precautions, you can safely enjoy the benefits of WD-40, just as I have. Here’s hoping to a squeak-free, rust-free future!
