Plexiglass (also known as acrylic) is a versatile, durable material used in everything from windows to furniture and protective barriers. It’s lightweight and shatter-resistant, but despite its toughness, plexiglass is prone to scratching.
If you’ve ever noticed unsightly scratches on your plexiglass surfaces, you might think the damage is permanent. But the good news is that most scratches can be buffed out, restoring your plexiglass to its original, clear state.
To remove scratches from plexiglass, clean the surface, then use fine-grit sandpaper or plastic polish to buff out the scratches. For deeper scratches, sanding and polishing in stages may be necessary to achieve a smooth, clear finish.

Why Does Plexiglass Get Scratched?
Even though plexiglass is stronger than glass, it scratches more easily. This is because the material, while durable, is softer than traditional glass, making it vulnerable to scratches from regular wear and tear. Common reasons for scratches include:
- Improper cleaning: Using harsh or abrasive cleaning cloths or chemicals can scratch the surface.
- Accidental contact: Bumping or sliding objects across plexiglass can create scratches.
- Environmental factors: Plexiglass installed outdoors may experience scratches from dirt, debris, or exposure to extreme weather conditions.
Knowing how to properly care for and restore plexiglass is essential if you want to keep it looking its best. The good news is, with the right tools and methods, you can remove most scratches and get your plexiglass surfaces back to their crystal-clear appearance.
Step-by-Step Guide to Remove Scratches from Plexiglass
Depending on the depth of the scratch, you can often remove or significantly reduce its appearance using basic tools and materials. Here’s a comprehensive guide on how to remove scratches from plexiglass, covering everything from light scuffs to deeper marks.
Step 1: Clean the Plexiglass
Before attempting to remove the scratch, make sure the surface is free of dirt and debris. If you try to buff out a scratch on a dirty surface, you risk creating more scratches.
- Use a gentle cleaner: Choose a mild soap or a plastic cleaner that is specifically formulated for acrylic surfaces. Avoid harsh chemicals like ammonia or window cleaner, as these can damage plexiglass.
- Wipe with a microfiber cloth: Gently clean the scratched area using a microfiber cloth. Avoid using paper towels or rough fabrics, as these can cause further damage.
- Dry thoroughly: Once clean, dry the area completely with another soft microfiber cloth. Now the surface is ready for repair.
Step 2: Assess the Scratch
Before deciding on the best method for scratch removal, determine how deep the scratch is. Here’s a quick way to assess:
- Light scratches: These are surface-level marks that are visible but cannot be felt when you run your finger over them.
- Deeper scratches: If you can feel the scratch when you lightly drag your fingernail across it, it’s a deeper scratch, which may require more effort to repair.
Step 3: Use a Plastic Polish for Light Scratches
For light, surface-level scratches, a plastic polish can work wonders. These products are designed to smooth out and fill in minor scratches, restoring the clarity of your plexiglass.
- Apply plastic polish: Use a high-quality plastic polish (such as Novus or Plexus) that’s made for acrylic surfaces. Apply a small amount to a soft cloth and rub it onto the scratched area in small, circular motions. Focus on the scratch but blend the polish around the surrounding area to maintain an even appearance.
- Buff gently: Continue rubbing in circles, applying gentle pressure. After a few minutes, you’ll start to see the scratch fade. Wipe away any excess polish with a clean microfiber cloth and check the results. If needed, reapply the polish until the scratch is no longer visible.
Pro Tip: Make sure to read the instructions on the plastic polish for optimal results, as different brands may have slightly different usage directions.
Step 4: Use Fine-Grit Sandpaper for Deeper Scratches
If the scratch is deeper and can’t be removed with polish alone, you’ll need to use a sanding method. Sanding may sound extreme, but when done carefully, it can help restore plexiglass surfaces to their original clarity.
- Start with fine-grit sandpaper: Begin with a fine grit, such as 600-grit sandpaper, to gently sand out the deeper scratches. Wet the sandpaper and the plexiglass surface to reduce friction, then sand the scratched area lightly in straight, consistent strokes. Keep the pressure even and don’t rush the process—this is key to avoiding further damage.
- Move to higher grits: Once the scratch is less visible, move to higher grits (800, 1000, and eventually 2000 grit). This process will smooth the surface and prepare it for final polishing. Wet sanding helps prevent overheating and makes for a smoother finish, so continue using water as you sand.
- Polish after sanding: After sanding with high-grit paper, follow up with a plastic polish as outlined in Step 3 to restore the glossy finish. The sanding process will have removed the deeper scratch, but polishing will bring back the shine and clarity.
Pro Tip: Be patient! Sanding too aggressively can cause cloudiness in the plexiglass, so it’s better to go slow and check your progress frequently.
Step 5: Buff with a Polishing Compound for a Professional Finish
For a final touch, buffing with a polishing compound can enhance the clarity and shine of your plexiglass surface.
- Apply the compound: Using a clean, soft cloth, apply a small amount of polishing compound to the surface. You can also use a buffing pad for larger areas. Again, work in circular motions to distribute the compound evenly.
- Buff until clear: Buff the surface gently but thoroughly until the polish is absorbed, and the area looks smooth and clear. This step ensures that any fine scratches or cloudiness left from the sanding process are polished away.
When to Call a Professional to Remove Scratches
In some cases, scratches might be too deep to fully repair at home, especially if the plexiglass has been gouged or cracked. If sanding and polishing don’t fully restore the surface, or if the damage is extensive, it may be time to call in a professional.
Experts can often remove even the most stubborn scratches using specialized tools and techniques, or they may recommend replacing the damaged piece entirely.
Preventing Future Scratches on Plexiglass
Now that you’ve restored your plexiglass to its original clarity, it’s important to protect it from future damage. Here are some tips to keep it scratch-free:
Use the Right Cleaning Materials
Always use a soft microfiber cloth when cleaning plexiglass. Harsh cleaning materials like paper towels or scouring pads can cause scratches.
Choose Plexiglass-Safe Cleaners
Avoid ammonia-based cleaners, like standard window cleaners, which can cause the plexiglass to become cloudy and increase the risk of scratching. Use products specifically made for acrylic or mild soap and water instead.
Handle with Care
Be mindful when placing heavy or sharp objects near plexiglass surfaces. Avoid dragging anything across the surface that could cause scratches, and place protective covers or pads on plexiglass furniture or windows if necessary.
Apply a Protective Coating
Consider using a protective wax or coating on your plexiglass surfaces. These products add an extra layer of protection against minor scratches and can keep the material looking clear and shiny for longer.
Final Words
Scratches in glass don’t have to be permanent. With a few simple tools—such as plastic polish, fine-grit sandpaper, and a microfiber cloth—you can easily buff out light to moderate scratches and restore your plexiglass surfaces to their former clarity. For deeper scratches, sanding in stages and polishing afterward can make a world of difference.
Remember, the key to a successful scratch removal is patience. Take your time with each step, and you’ll be rewarded with a smooth, scratch-free plexiglass surface. And once your plexiglass is restored, following a few preventive tips will help keep it looking new for years to come.
