How to Clean Shower Doors with WD-40

Is your shower door covered with ugly hard water spots and soap scum? You’re not alone. In fact, a foggy, stained glass shower door is every homeowner’s problem. Even if you devote enough time to cleaning shower doors, they still get dirty eventually.

If only there was an effective cleaning solution that could help prevent shower door stains and spots for the long haul.

The good news is, there is such a product. If you haven’t heard about it yet, WD-40 could change how you clean and maintain your glass shower doors. While your usual quality bathroom cleaning spray can break down soap scum and kill mold in the shower, WD-40 could be a game-changer for shower doors because it displaces water.

If you’re tired of trying to clean water spots and stains on glass shower doors to no avail, find out how WD-40 can clean even the most stubborn water stains and more. But there’s a secret – you have to know how to apply WD-40 on the shower door a certain way.


Can You Clean Shower Glass with WD-40?

A clean glass door can make the shower area look and feel more hygienic as it should. And yes, WD-40 can keep your shower glass free of common stains in the shower, from soap scum to hard water spots.

WD-40 is a multipurpose cleaning product that works faster and easier than your typical shower cleaning solutions. It can almost instantly remove anything from dirt and grime buildup, soap scum, water spots, and rust stains on a glass door.

Overall, WD-40 offers quick and convenient removal of almost anything staining your shower glass, keeping it sparkling clean for much longer. Even better, WD-40 is not as harsh as many other cleaning chemicals used in the shower.

Does WD-40 Get Rid of Hard Water Stains on Shower Doors?

Yes, absolutely. WD-40 works on any hard or stubborn stains, including the residue from hard water in your shower. It can eliminate mineral stains inside out and works quickly at dissolving hard water stains as well.

WD-40 contains an abundance of alkane compounds, which boost its effectiveness, especially when it comes to dry cleaning and spot removal. This is why this cleaning product is effective against getting rid of even the most stubborn hard water stains on a glass shower door.

What’s even better is that using WD-40 to clean a shower door of limescale will also help prevent water stains from appearing in the glass for at least a couple of months.

Is WD-40 Safe for Shower Glass?

WD-40 is an all-around cleaner, and it’s safe to use on your shower glass. It’s one of the easiest solutions to maintain a clean and shiny glass door. The alkaline content of WD-40 isn’t enough to break the molecular bonds of the glass.

Still, it doesn’t mean that you can use it on your shower glass without any precautions. Leaving WD-40 on the shower door for too long wouldn’t be a good idea since it could cause more spots and stains to appear.

How to Clean a Shower Door with WD-40

Cleaning shower doors with WD-40 is pretty quick and easy. You can follow these three simple steps when using WD-40 to obtain spot-free and shiny shower doors – spray, wipe, rinse.

Step 1. Spray WD-40 on the Shower Door

No preparations are necessary. Start off by directly spraying an ample amount of the cleaner on the affected areas of your shower door. Remember that WD-40 will only work on places it comes in contact with, so make sure you cover every spot on the glass that needs to be cleaned.

After spraying WD-40 on all stained areas of your shower door, leave the solution alone to work on your stains for 15 to 30 minutes. This will allow the cleaner to work through hard water deposits and stubborn buildups, loosening their bonds and dissolving them in the process.

Step 2. Wipe the Glass with Clean Cloth

Generally, it’s important to give the WD-40 solution ample time to do its work. But that doesn’t mean it’s a spray it and leave it kind of cleaning solution. 

Once you’ve given it enough time to work its magic on the hard water stains and soap scum, always wipe the solution away using a clean microfiber cloth. But if there is still some stain residue, don’t hesitate to reapply the solution and use a scrubbing brush instead.

Reapply and scrub affected areas as many times as necessary until the soap scum and hard water stains on the glass disappear completely.

Step 3. Shine the Shower Door with a Final Coat of WD-40

Once you make sure that there are no remaining stains on the glass door, the final step is to wash away the loose dirt. With a bucket full of clean water or by using the showerhead, rinse the shower door thoroughly. Although this step might not be necessary in most cases, as WD-40 doesn’t need any rinsing, you might want to wash off any loose dirt and limescale deposits.

And don’t forget to dry out the shower door with a clean, dry towel to avoid any more water spots. You can also apply a final coat of WD-40 on the shower door, then wipe it again with a clean cloth to give the glass a good shine.

Safety Tips When Cleaning Shower Doors with WD-40

When using WD-40 for cleaning shower doors, keep these safety tips in mind:

  • Keep the shower or bathroom area well-ventilated before spraying WD-40 on the shower door. Open the shower door and window or turn the bathroom fan on to ensure maximum ventilation.

  • Put a face mask on before using this cleaning product. You can also use a handkerchief to cover both your mouth and nose to avoid inhaling toxic fumes.

  • Wear rubber gloves when handling this product.

  • Avoid using rough, hard, or abrasive items when cleaning or scrubbing the shower doors to avoid any damage to the glass surface. Use a microfiber cloth or a brush with soft bristles instead.

Final Thoughts

So, now you know how to clean shower doors with WD-40. Following these three steps – spray, wipe, and shine – through this method, you can get rid of almost any dirt or stains on glass shower doors, including soap scum, rust stains, and hard water deposits.
