What Is WD-40®?

WD-40® is a popular multi-use product known for its water-displacing properties and lubricant abilities. It was invented in the 1950s to protect machinery from rust and corrosion, but it’s become a common household staple, often used for tasks such as loosening stuck bolts, removing adhesive residues, and even quieting squeaky hinges. However, its versatility has also led people to experiment with unconventional uses, including cleaning car windshields.

What Are the Benefits of Using WD-40® on a Windshield?

WD-40® is touted for its ability to remove tough grime and sticky residues on most surfaces, which could seem like a quick fix for automotive glass problems. Some of the claims that make WD-40® attractive for windshield cleaning include:

Removing sticky substances such as bugs, sap, and sticker adhesives
Cleaning without streaks when applied and wiped correctly
Assisting with frost and ice removal, acting as a temporary shield against build-up

How to Use WD-40® on a Windshield

While the claims of WD-40®’s cleaning capabilities may sound appealing, you must use caution if you’re going to apply it to your windshield. Keep these things in mind:

Spot Test First – Before covering your entire windshield with WD-40®, test an inconspicuous area on the window first to see how it responds.
Apply to a Microfibre Cloth – If the test spot remains clean and clear, spray WD-40® onto a cloth to clean the windshield instead of directly on the glass.
Use It Minimally – Don’t use too much. A little goes a long way.
Wipe Clean – Use a clean, dry microfibre cloth to clean the windshield thoroughly. Any leftover residue may cause a glare or leave a haze.

Risks of Using WD-40® on Windshields

Despite its benefits in other applications, WD-40® is not the best choice for cleaning windshields, and it’s important to consider these risks before you make this the go-to choice for your vehicle:

Greasy Residue – WD-40® leaves a greasy film that can be challenging to remove. While initially the glass may appear clear, the residue can collect dust and dirt over time if it’s not completely wiped clean, making your windshield grimier than before.
Streaking Issues – If any WD-40® remains, streaks across the glass are another possible issue, which worsens visibility rather than improves it.
Hazy Film – Overapplication of WD-40® can result in a hazy appearance on your windshield, affecting clarity.
Risk to Vehicle Finish – If WD-40® comes into contact with your car’s paint, it can harm the finish over time. You’d need to take extra precautions to avoid accidental overspray.
Wiper Damage – WD-40® on windshield wipers can remove the graphite or Teflon layer and dry out the rubber, requiring more frequent replacement.

Safer Alternatives for Windshield Maintenance

If you want to ensure your windshield remains clean without risking damage to your vehicle, here are some better options to consider:

Auto Glass Cleaners – These are specifically designed to tackle road grime, grease, and bugs without leaving streaks or harming the glass. Always use ammonia-free products to avoid damaging tint or rubber seals.
White Vinegar and Distilled Water – This safe and effective homemade method will cut through dirt and grease without leaving a harmful residue.
Windex – Glass cleaners like Windex will clear dirt and clean your windows. However, unlike auto-specific glass cleaners, they’re less effective in combating road grime for lasting results.
Auto Glass Solutions – Our water repellent for windshields helps repel rain, sleet, and snow, as well as the dust and dirt that comes with them, for extended protection. Ensuring your windshield wipers are in good condition will also keep your windshield cleaner.
