How to Remove Wiper Scratches from Your Windshield



Windshield scratch repair is not just about aesthetics – it is about ensuring optimal driving conditions. Scratches, often caused by worn wiper blades, can even weaken the glass. Sun glare bouncing off scratches can significantly hinder visibility, and rainwater pooling in the grooves can leave your wipers struggling to keep up.
The good news? Minor scratches are often fixable without a complete windshield replacement. While severe damage calls for a professional’s touch, you can try using auto glass repair kits to fix minor windshield scratches.
Wondering how to remove wiper scratches from the windshield? We will discuss effective methods for restoring clarity to your windshield, whether the damage is minor or more severe. By implementing appropriate repair solutions, you can eliminate imperfections and reclaim a clear line of sight for a safer driving experience.

Identifying Wiper Scratches: Tips

Determining the source and extent of the damage is essential to successfully repair windshield scratches. With this knowledge, you may decide the best course of action to ensure a clean view and the optimum driving circumstances.
Before beginning any scratch repair work, clean your windshield thoroughly on the inside as well as on the outside. Occasionally, what seems to be a scary scrape is just a build-up of grit or residue.
Let us now address the matter at hand. Do we have a chip or crack here, or is it just a scratch? The key to identifying scratches lies in their feel. Run your fingernail gently across the suspected imperfection. If your fingernail catches a snag, it is likely a scratch.
Deeper scratches will cause your fingernail to dig in more noticeably. Unfortunately, these deeper blemishes might require more involved repair methods, and some home remedies might not be as effective.

A Guide to Repairing Windshield Scratches

There are two main approaches to repairing windshield scratches: filling it in or polishing it out.
1. Filling the Scratch (Making it Less Noticeable)

  • Wax it Up: Apply a small amount of paste wax to the scratch and surrounding area and buff it off with a cloth after it hazes. Repeat, building thin layers until the scratch is less visible. Remember, the wax only fills the gap; it does not erase the scratch itself. Reapply every few months for lasting results.
  • Clear Nail Polish (for Shallow Scratches): Apply a thin layer of clear nail polish over the scratch. Similar to wax, this fills the scratch to make it less noticeable. You can add more layers for deeper scratches, but keep them thin to avoid a bumpy finish. Don’t like the results? Nail polish remover can take it all off.

2. Polishing the Scratch (Removing the Edges)
This method involves using a store-bought wiper scratch remover or an abrasive compound to buff down the scratch’s raised edges, essentially making them disappear. 

  1. Clean Up: Start with a clean slate. Use glass cleaner and a cloth to remove any dirt or debris from the area.
  2. Apply & Buff: Apply a small amount of the chosen compound (cerium oxide, plastic scratch remover, or even toothpaste if you’re in a pinch) to the scratch. Using a cloth, buff in a circular motion with gentle pressure. As the compound dries, keep it moist with a light mist of water while continuing to buff.
  3. Power Up (Optional): Consider using a buffer attached to a drill to polish windshield glass. Maintain control and keep it focused on the scratch. Avoid overheating the glass with high speeds; aim for 1,000 rpm or less. Longer scratches might benefit from an orbital polisher with a small pad.
  4. Check & Repeat: Regularly pause to clean off residue and assess your progress. The goal is to gently smooth the scratched edges until your fingernail no longer catches in it. Repeat buffing as needed.
  5. Clean & Inspect: Once satisfied, clean the glass thoroughly. If the scratch is still present, it might be time for professional help or a windshield replacement. These fixes work best for minor scratches.

Seeking Professional Help for Major Windshield Scratches

While minor imperfections can be tackled with a trusty wiper scratch remover, more extensive damage requires the expertise of a professional.
Seek Professional Help When:

  • Scratches Impede Visibility: Scratches that severely block your eyesight, especially those within your direct line of sight, can become a safety hazard. Professionals can analyze the severity of the damage and offer the best course of action, be it repair or replacement.
  • Scratches are Deep or Extensive: Deep scratches that gouge the glass surface require specialist procedures and tools outside the realm of DIY efforts. Professionals have the training and equipment to effectively address these deeper blemishes.

Professional Solutions

  • Windshield Repair: Windshield repair could be a viable choice for certain instances, like minor cracks or chips. Professionals use specific resins and methods to repair the structural strength of the windshield.
  • Windshield Replacement: If the scratch is extensive or affects the overall strength of the windshield, a full windshield replacement may be needed. Experts ensure the new windshield is correctly installed, guaranteeing ideal visibility and structural integrity.

Preventive Measures to Avoid Windshield Scratches

A clear windshield is crucial for safe driving. Here are some proactive steps you can take to keep those pesky scratches at bay:

  • Wiper Care: Always wet your windshield before using the wipers to avoid grinding dust like sandpaper. Remember, wiper blades wear out, especially in hot climates. Replacing them regularly (consult your car’s manual for recommended intervals) is a small investment that pays off in maintaining a clear view.
  • Top Up the Reservoir: Ensuring a full wiper fluid reservoir is a simple yet effective way to prevent scratches. A good quality wiper fluid eliminates dirt and debris while lubricating the wiper blades and minimizing friction against the glass.
  • Cleaning Cautions: Improper cleaning can introduce scratches on your windshield. Always use a soft microfiber cloth for wiping down the glass, and thoroughly rinse it with water to remove any loose dirt or debris before you start cleaning. Avoid using cleaners with ammonia, as this can dehydrate the glass and lead to cracks over time.
  • Parking Smart: Your windshield is exposed to environmental factors such as dust, leaves, and flying debris while your automobile is parked outside. These elements can build up over time, resulting in tiny scrapes. These scrapes may get worse with time and impair your eyesight. To reduce exposure to these factors, keep your automobile in a garage or an enclosed location whenever possible. If you cannot access a closed parking spot, use a cover to protect your vehicle.
  • Early Intervention: Address any minor scratches you notice promptly by seeking professional repair from a reputable car care service. A higher-quality service might save you money over time by avoiding the need for a windshield replacement.
