How to Remove Scratches from Glass: Top DIY Methods

We definitely know that frustrating feeling one gets when there's a visible scratch on a glass surface that is used every single day! But don't worry! If the scratch is not deep, you may be able to fix it yourself - whether it's on your window, glass stove, or glass table.

So, the first step is to check how deep the scratch is and what kind of glass you'll be working on. Then, you can try some DIY fixes, which we'll discuss below. If they don't work, you'll have to get professional help.

As such, if you want to learn how to remove scratches from glass, keep reading!

Key Takeaways

• Test how deep the scratch is with your fingernail and identify your glass type (tempered, coated, etc.) to choose the correct method.
• Use household items like baking soda, toothpaste, or nail polish to buff out light surface scratches.
• For deep scratches or special glass, try commercial products or seek professional help to avoid further damage.

How Deep Is the Scratch?

Before you decide which method to use to remove scratches from glass, check how deep the scratch is. Run your fingernail over the scratch - if it slides smoothly, it's likely a surface scratch you can easily buff out with DIY remedies mentioned below.

If your nail catches on the scratch, you'll likely have to use a specialized polishing compound or a commercial scratch removal kit.

If the scratch is so deep that it weakens the glass or starts spreading, it's usually beyond DIY repair. You probably won't be able to fix these by yourself. So, if your glass surface has a very deep scratch, you should call a professional to prevent further damage to the glass.

What Glass Type Are We Talking About?

Before you choose a method to remove scratches from glass, assess what type of glass you're dealing with. Below, you'll find a comprehensive list of different types of glass with tips and precautions for each.

1. Tempered Glass

Characteristics:

• It is used in windows, car windshields, shower doors.
• Tempered glass is heat-treated for strength and shatters into small, less dangerous pieces when broken.
• It’s more resistant to impact than regular glass but can still develop scratches.

Risks & considerations:

• Tempered glass can have minor scratches buffed out using appropriate techniques, but this must be done with extreme caution; buffing too much can weaken its surface integrity.
• If a corner or edge is damaged, the entire glass can shatter instantly because of built-up tension.
• Small surface scratches won’t usually lead to breakage, but deep cracks or scratches near the edges are riskier.
• Best method: use a glass polishing compound and a dampened microfiber cloth; avoid abrasive cleaners like steel wool.

2. Laminated Glass

Characteristics:

• It is used in car windshields, windows, and skylights.
• Made of two glass layers with a plastic interlayer (usually PVB); more durable than other glass types.
• If cracked, laminated glass pieces are kept together by the plastic interlayer.

Risks & considerations:

• Surface scratches can be polished out, but deeper ones may expose the plastic interlayer, weakening the glass.
• Do NOT use strong abrasives; you risk damaging the outer layer and reducing clarity.
• Best method: use a glass polishing compound or a mild abrasive like baking soda or toothpaste.

3. Coated or Tinted Glass

Characteristics:

• It is used in Low-E windows, privacy glass, car windows.
• It has a thin coating to reduce UV rays, glare, or heat.
• It is common in energy-efficient windows and automotive glass.

Risks & considerations:

• Scratches on coated glass cannot be polished out; you risk removing the coating entirely.
• Using abrasives, like baking soda, toothpaste, or steel wool, and sharp objects, like plastic scrapers or razor blades, is a BIG NO—they’ll ruin the finish.
• Best method: use a gentle glass cleaner and lint-free cloth; if damage is severe, you may need to replace the glass.

4. Standard Annealed Glass

Characteristics:

• It is used in windows, mirrors, and picture frames.
• It is regular glass that breaks into large, sharp shards when shattered.
• It is most forgiving when it comes to scratch removal—light scratches can be buffed out.

Risks & considerations:

• It can be polished, but too much pressure may cause cracks.
• Best method: use toothpaste, baking soda, or glass polishing compounds.

5. Textured or Frosted Glass

Characteristics:

• It is used in decorative or privacy windows and bathroom doors.
• It has an etched or patterned surface, making scratches harder to see.

Risks & Considerations:

• Scratches are harder to fix because polishing may remove the textured effect.
• Best method: gentle cleaning with a microfiber cloth and non-abrasive polish; don't use anything rough.

Effective DIY Methods for Removing Scratches from Glass

DIY solutions can be surprisingly effective for minor scratches on glass - whether it's on a window, glass stove top, or another glass surface. Plus, you'll need readily available household items. You probably already have everything you need to get the job done, so let's get started!

1. Baking Soda Paste Method

Baking soda is a gentle abrasive and it can help you buff out minor scratches. Here's how to use it:

• Mix two parts baking soda with one part water to create a thick paste.
• Use a clean microfiber cloth to apply the baking soda paste to the scratched area.
• Rub the paste gently in circular motions for about 30 seconds. The circular motion ensures even application and helps smooth out the scratch. Be careful not to press too hard - baking soda is, after all, mildly abrasive, and too much force could make things worse.
• Use a damp cloth to wipe away the excess paste and check if the scratch is still visible.
• If the scratch is still visible, repeat the process.

Just be patient. This method might take a few tries to yield results, but the effort is totally worth it!

2. Toothpaste Method

If you don't have baking soda or you've already tried the baking soda paste method and it didn't work, grab some toothpaste. It's generally recommended to use non-gel toothpaste because it contains mild abrasives.

Here's how to remove scratches from glass windows or glass cooktops with toothpaste:

• Put a small amount of toothpaste onto a damp microfiber cloth.
• Rub the scratched area in circular motions for 30 seconds to a minute. The mild abrasives in the toothpaste will gradually smooth out the scratch. You can also use a plastic scraper to gently scrape along the scratch.
• Then, wipe off the excess toothpaste with a clean, damp cloth and check the results.
• If needed, repeat until the scratch is barely noticeable.

3. Nail Polish Method

Clear nail polish is excellent for minor scratches, as it literally fills them, making them almost invisible. Here's how to remove scratches from glass with nail polish:

• Apply a thin layer of clear nail polish over the scratch with the applicator brush.
• Cover the entire scratch evenly. Don't worry about the surrounding surface - we'll get to it.
• Let the nail polish dry completely. It may take a few hours.
• Once dry, use nail polish remover and a soft cloth to gently wipe away the excess polish around the scratch.

4. Metal Polish or Jeweler’s Rouge Method

If the scratch is slightly deeper and you can't remove it with baking soda, toothpaste, or nail polish, try a fine metal polish or jeweler's rouge. These products contain fine abrasives that work on both glass and metal. However, keep in mind that not all metal polishes can be used on glass. Some may contain chemicals or abrasives that are too harsh and could further damage the surface. It's best to use a product specifically labeled as safe for glass.

Here's how to remove scratches from glass using this method:

• Apply a small amount of polish on a soft cloth.
• Gently rub the scratched area in circular motions. This smooths out the scratch by wearing down its edges.
• After a few minutes, wipe the area clean and inspect the results.
• If necessary, repeat the process. However, don't overdo it, or you could leave the glass cloudy.

5. Steel Wool

You can also use steel wool to remove scratches from glass, but it's extremely important to choose super fine-grade #0000 steel wool. Otherwise, you risk making things worse.

However, even #0000 steel wool can irreparably damage certain glass types, such as coated, tinted, or tempered glass. Therefore, this method should be considered a last resort for uncoated annealed glass only and tested in an inconspicuous area first. If you don't notice any visible scratches after applying a bit of pressure, you can use it on the scratch you want to remove:

• Clean the glass first. Use a mild glass cleaner and a microfiber cloth to remove any dirt or debris that could cause additional scratches.
• You can apply a mild soapy solution to the surface before using steel wool. This can minimize the risk of additional scratches.
• Gently buff the scratch. Use light pressure and move the steel wool in circular motions over the scratched area. Continue for 30-60 seconds.
• Wipe the area with a clean microfiber cloth and check if scratch is gone.
• If necessary, repeat the process, but make sure not to overdo it.

6. Commercial Products for Scratch Removal

If you can't remove the scratch with DIY methods, try some commercial products. They are designed specifically to remove scratches. These products usually come in kits that contain everything you need for this process.

Commercial glass repair kits typically contain cerium oxide, which is the preferred professional compound for glass polishing. These kits are substantially more effective than household methods for moderate scratches but may still not work on deep scratches. Either way, it's extremely important to follow the manufacturer's instructions to avoid damaging the glass.

Typically, you'll have to apply a polishing compound to a buffing pad and then rub it over the scratch in circular motions. After polishing, wipe away any excess with a clean cloth and check the results.

You can also use a glass filler kit designed specifically to make glass scratches disappear! These kits contain everything you need to fill the scratch with durable resin.

Preventing Scratches on Glass

To prevent scratches on glass, follow these tips:

• Use a microfiber cloth and gentle cleaning methods instead of abrasive materials. Always avoid harsh chemicals on surfaces that are not scratch-proof.
• Avoid using paper towels or rough sponges, which can cause micro-abrasions that build up over time and lead to more scratches.
• Regularly clean hard water stains, as mineral buildup can etch the glass and cause damage over time.
• Apply scratch-resistant technologies such as glass protectants. They can create a barrier against potential scratches and can be incredibly useful for surfaces that are used on a regular basis - e.g. windows that are opened and closed often, glass stovetops, and glasses - properly protecting these against those annoying scratches.
• If you're worried about small scratches on glass tables, which are the easiest glass surfaces to scratch, use coasters or mats to protect the glass. If you're worried about scratches on glass top stoves, make sure to use specialized cooktop cleaning solutions and avoid using cookware like uncoated cast iron on them.

When to Seek Professional Help

DIY methods work well for minor scratches, but you may still require professional repair in some cases. For example, if a scratch is too deep, affects visibility, or turns into a crack, it’s best to get expert help.

Professionals have the right tools and techniques to repair severe damage, especially on tempered or coated glass. In other words, if you're not sure how to handle it, don’t risk making things worse—let a professional handle it. In some situations, you may have to replace the glass surface altogether. For example, if the glass-ceramic stove top is severely scratched, it's risky to continue using it, as it may crack or shatter.

Frequently Asked Questions

Can you take scratches out of glass?

Yes, you can take scratches out of glass, but it depends on how deep the scratch is. You may be able to buff out light surface scratches with DIY fixes like toothpaste or baking soda. If the scratch is deep enough that you can feel it with your fingernail, you might need professional repair or even glass replacement.

Does baking soda actually remove scratches from glass?

Baking soda is mildly abrasive, so when mixed with water to form a paste, it can help remove surface scratches from glass. But don’t expect miracles—if the scratch is deep, baking soda won’t make much of a difference. Also, be careful not to rub too hard, or you might end up making the glass even hazier.

Does toothpaste remove scratches from glass?

Yes, toothpaste can remove surface scratches from glass but only if it’s a non-gel, white toothpaste (the gritty kind). It works similarly to a mild polish - it smooths out tiny surface scratches.

Does WD 40 remove scratches from glass?

WD-40 is a lubricant, so it does not remove scratches from glass. But it can make them look less noticeable. Once it wears off, the scratch will still be there.

When should I seek professional help for scratched glass?

You should seek professional help if the scratch is deep, impacting visibility, or if you're seeing cracks. It's especially important for tempered or coated glass, as it requires specialized repair.
