How to Clean Shower Doors With WD 40? (Fast & Easy Steps)

Shower doors look elegant in your modern bathroom design, but it turns into a nightmare when water spots and soap scum start to build up on the surface. You’ve probably used all types of DIY methods, but that stubborn dirt and hard water stains are still there.

The good thing is that WD 40 is here to help you out. No matter what kind of dirt or soap scum your shower door has, WD 40 can always help you remove it.

It’s the best solution, but you need to know how to clean shower doors with WD 40. We made a step-by-step guide so you can effectively remove the stubborn dirt in your shower doors.

How to Clean your Shower Doors Using WD 40

Cleaning your shower doors with the use of WD 40 is very easy and straightforward. You don’t need to be an expert and you don’t need to mix any chemicals as well. The WD 40 is ready to use so the process is very simple and easy to follow. Here are the things that you need to know:

Tools and Materials

  • Clean and dry Microfiber towel
  • WD 40
  • Safety Mask
  • Rubber Gloves (Optional)

Step 1: Safety is your Priority

You won’t get bruises or cuts by using WD 40, but it is not a good idea to inhale it because it can cause different kinds of respiratory problems. Wearing a face mask is a must because WD-40 is also a kind of chemical. If you don’t have a mask, you can tie a handkerchief or use clothing to your mouth and nose.

Make sure that you open all the doors and windows of your bathroom. This is done so the smell would not stay in an enclosed space.

You can also wear rubber gloves if you have them at home. This would be perfect if you have skin allergies. These safety precautions are very important to prevent health issues.

Step 2: Spray WD 40 on your Shower Door

You don’t need to make preparations or mix any chemicals. All you need to do is open the WD 40 and start spraying liberally on the affected areas. Remember that WD 40 will only work on the sprayed areas so you have to cover all the spots that you want to clean on the glass door.

After successfully spraying the WD-40 on the stubborn stains and dirty areas of the shower door, you have to leave the solution on the surface for about 15 to 30 minutes. This is done to make sure that the cleaner can soften the deposits and other stubborn buildups on the surface.

WD-40 can loosen their hold on the glass door and they would be dissolved during the waiting time. This would make it easier for you to just wipe off the dirt and debris on the surface without the need for serious scrubbing.

Take note that if the dirt and other buildups are still there after waiting for 30 minutes, you can wait for a few minutes more to make sure that they soften up. You don’t want to scratch your glass shower door by scrubbing the surface so you’ll have to wait for the dirt and dust to become loose.

Wipe the Glass with your Microfiber Towel

Step 3: Wipe the Glass with your Microfiber Towel

The microfiber towel is the best option if you are removing dirt and dust from the surface of your shower door. Although a cotton towel can do the trick, microfiber cloth is more effective for this kind of job. Other towels will only push the dirt and dust around the surface while microfiber can pick them up.

The WD-40 can pretty much handle all the dust and dirt buildup on the surface. It doesn’t matter if it’s been there for a long time or it’s just a new stain. If you leave the chemical on the surface for a few minutes, you can just wipe them off with your microfiber towel.

If you notice that there is still some dirt or rust stain on the surface, you can use your microfiber towel to scrub the surface gently. This is not something that a typical towel can do, which is why we recommended the use of a microfiber towel. Scrub the surface gently and clear all the moisture and dirt from the surface.

Step 4: Reapply WD-40 When Needed

If the stains have been there for a long time, you can expect that they won’t come off with just a few sprays of WD-40. Don’t be scared to reapply if needed. There won’t be any negative repercussions of doing so. Just make sure that you leave the solution on the surface for 15 to 30 minutes before you wipe it off.

Step 5: Clean the Surface of the Shower Door

Cleaning the shower door after using WD-40 can be done in two ways:

  • Use a dry microfiber towel to clean the surface of the shower door. Since WD-40 can pretty much dissolve most of the dirt and scum from the surface, a microfiber towel can remove the remaining dirt effortlessly.
  • You can rinse the surface with water if you want. Removing WD-40 with the use of a clean cloth is enough, but it’s not a bad idea to rinse the surface with water and dry it off with a clean cloth afterward.

You can also reapply WD-40 after cleaning the shower doors. This is done to give it a good shine.

Maintaining your Shower Doors

Maintaining your Shower Doors

WD-40 can handle almost any kind of dirt or accumulation of soap scum on the surface of your shower doors, but do you really want to do this all the time? Although the cleaning process is very easy, there are simpler ways to keep your doors clean and prevent stubborn dirt from ruining their appearance.

We’ve got a few maintenance tips that you can consider if you want to make sure that your shower doors always look good.

1. Drying the Shower Door After Use

Most of you probably don’t have the time to do this, especially if you’re in a rush. However, make sure that you don’t let the day pass by without cleaning the shower door. Soap scum and dirt can accumulate after a few days. If you let this happen, it would be very difficult to scrub them off the surface.

If you’re not too busy, dry the shower door after using it. This would only take a few minutes of your time. With a microfiber towel, you can easily dry the surface of the door.

For people who are busy the whole day, you can ask someone to do it for you or you can clean it when you get home from work. You’ll probably need to clean yourself before you go to bed so spend a few minutes of your time wiping the shower doors.

Do your Research Before Using Cleaning Products

2. Do your Research Before Using Cleaning Products

WD-40 is a tried and tested product for cleaning shower doors, but you might find other products that are claiming that you can use them for glass surfaces. Before you buy and use them, you have to do your research first. Look for comments from previous users if it is really effective or not.

A good recommendation is to use other alternatives instead of buying other cleaning products. Here are some of the alternative cleaning products that you can find in your kitchen:

  • Baking Soda and Hydrogen Peroxide: Use a few drops of hydrogen peroxide and mix it with three tablespoons of baking soda. Once you’ve created a paste, scrub the mixture into the glass door, particularly on the affected area.
  • White Vinegar and Baking Soda: Just like with hydrogen peroxide, you need to make a paste using baking soda and white vinegar. Add white vinegar to the baking soda and stir it to make a consistent paste. Apply to your shower door and wait for 15 minutes before you rinse it.
  • White Vinegar and Water: Combine vinegar and water and spray it on your shower door. If you use a cup of vinegar, you need to add the same amount of water and put it in a spray bottle. Leave the solution on the glass door for 15 minutes and use a soft-bristled brush before rinsing it with water.

3. Clean Signs of Mild Right Away

It’s very easy to spot the signs of mildew on the surface. It causes a musty smell and you can see a greenish hue on the surface. Don’t just clean it with soap and water. Use a mold inhibitor or use vinegar to remove it.

Use one of the alternative cleaning solutions above to completely remove the signs of mold in your shower door.


As you can see, cleaning your shower doors is not as hard as you think. You don’t have to spend so much in hiring someone who can do it for you. As long as you know how to properly use WD-40 and other alternative cleaning solutions, the dirt and soap scum from your shower doors can be removed without a hitch.
