As touch screens and smartphones become more and more popular, screen scratches are not uncommon. Depending on the severity and location, these scratches can sometimes only be unsightly, but sometimes damage the whole device. While the worst scratches usually require a screen replacement, mild or moderate cases can be handled at home. You can try polishing with toothpaste (if it’s a plastic screen) or a glass polish (if it’s a glass screen). After the treatment is complete, you should use it carefully to prevent future scratches.
Steps
Use toothpaste (for plastic screens)

Prepare toothpaste. Toothpaste is a basic ingredient in the family medicine cabinet and indispensable in the morning. Because of its abrasive nature, toothpaste can erase scratches on plastic in a similar way to cleaning teeth. Toothpaste is often available at home without having to buy it, so it is often recommended to repair scratches on plastic. It is important to use cream toothpaste, as opposed to gel toothpaste. [1] X Research Source To be effective on scratches, toothpaste must be abrasive. Check the toothpaste box if you’re not sure what kind of toothpaste it is.
- Baking soda is just as abrasive as toothpaste. If you like using baking soda, you can mix it into a cream and use it as toothpaste.
Apply toothpaste with a suitable material. [2] X Research Resources This is a home solution, so there are no set rules for what materials to use. A soft cloth, paper towel, cotton ball or toothbrush can all be used. When dipping toothpaste, you should only take a pea-sized amount. More cream will make your phone dirty.
Apply toothpaste to the scratch. After dabbing the toothpaste, rub it gently in a circular motion. Continue scrubbing until the scratch is almost gone. Toothpaste is inherently abrasive, so you don’t need to rub it hard. Continue scrubbing until you start to see progress. Even if the scratch is so deep that it cannot be completely removed, the abrasive nature of the toothpaste will help smooth the scratches. [3] X Research Sources
- Toothpaste can’t remove deep scratches, but it will at least fade most scratches.
Wipe the phone clean. When the scratch has faded as desired, simply wipe off the toothpaste. The first step is to use a slightly damp cloth to wipe the toothpaste, [4] X The next source of research is to use a polishing cloth to wipe away dirt or oil from the screen. This way, you’ll refresh the look of your screen, and hopefully your phone will look even better than it did before it was scratched.
Use glass polish (for glass screens)

Buy cerium oxide glass polish. With a glass (instead of plastic) screen, you’ll have to use a stronger mixture than toothpaste or baking soda to remove scratches. In this case, you should use a cerium oxide polish. [5] X Source of Research This polish is available as a water-soluble powder, or as a premix. While pre-mixed products are obviously more convenient, it’s much more economical to buy the powder form.
- 100g of cerium oxide powder is more than enough for phone screen polishing. [6] X Research Source However, you may need to buy more just in case you have to deal with scratches later.
Mix the dough into a cream. [7] X Research Source If you buy cerium oxide powder, you will need to mix the mixture yourself first. Luckily this step is easy and well worth the money you save. Pour some flour (about 50-100g) into a small bowl. Slowly add more water until the mixture has a creamy consistency. Mix well by hand when pouring the water to ensure the correct consistency.
- The polish doesn’t need to be in exact proportions, as long as there is enough water to allow the polish to penetrate the material used to apply the screen.
- Skip this step if you purchased a pre-mixed polish.
Use adhesive tape to cover vulnerable spots. [8] X Research Source Cerium oxide polish can cause a number of problems for devices when it leaks into phone openings, including speakers, headphone jacks, or phone charging slots. This substance can also damage the camera lens. Therefore, you should isolate the place to be polished with adhesive tape, covering all vulnerable parts when in contact with the polish.
- Gluing the tape before wiping may seem a bit too careful, but it’s highly recommended that you do this before proceeding to prevent accidental damage to the phone.
Apply polish to the scratch. Dip a polishing cloth into the cerium oxide mixture and rub vigorously over the scratch with a circular motion. [9] X Research Source Regularly check for scratches while scrubbing. Every 30 seconds, you should use the other end of the towel to wipe off the mixture, add a new amount and repeat the process for maximum effectiveness.
- When using abrasive polishing products, you need to scrub harder than you would with a normal wipe. However, you also need to make sure not to scrub too hard. There is nothing worse than creating new cracks when you are trying to fix old ones.
Wipe again. After you’ve treated the scratch and wiped away the polish, it doesn’t hurt to use a polishing cloth for a quick wipe again. This way, you will clean away the grit that appears during the polishing process. Peel off the tape you applied before polishing and cleaning the phone. This step takes less than a minute or two, but you’ll be amazed at how beautiful your phone is once the smudges are removed.
- You should regularly clean the phone screen. Wiping twice a day may seem like a lot, but it only takes a few seconds to ensure the screen is clean.
Prevent scratches

Buy a screen protector. Mobile phones have never been as fragile and easily scratched as they are today. Screen protectors are an accessory you should think about if you’re worried about damage to your device. Regular phone stickers don’t cost much and will be much more economical than replacing the screen if unfortunately the screen is badly damaged. High-end ones are nearly unbreakable, regular ones at least help prevent damage.
- Between the plastic screen protector and the tempered one, it’s best to buy the latter. Tempered protectors are more durable, easier to see, and more pleasant to the touch. [10] X Research Source

Clean the screen regularly. Small scratches will appear if you leave the grit on the screen. It is recommended to clean the phone screen with a microfiber or silk cloth twice a day to maintain the best condition. [11] X Research Source If your phone has a touch screen, cleaning the screen is even more advisable, as oil and fingerprint build-up will stain and dim the screen.
- Clothing fabrics such as shirt sleeves, even dishcloths can also make screen wipes, although it’s best to use a softer material like silk or microfiber to protect your phone’s screen.

Keep your phone in a safe place. Phones often get scratched or damaged when you take them somewhere. It is important that you think about why the scratch appeared. Store your phone in a separate compartment instead of with a bunch of keys or coins. If possible, put your phone in a zippered pocket in case it falls out.
- Do not put your phone in your back pocket. In addition to the risk of cracking the phone screen if you accidentally sit on it, there is also the risk of neurological problems due to the phone putting pressure on the buttocks. [12] X Research Source
Advice
- Scratched phones are a very common problem, so there are many professional services that can help fix this problem quickly. If the scratch is quite severe or if you don’t have time to fix it yourself, you can search online for a phone repair shop near you. Note that some places charge quite a bit, so you should try to handle it yourself first.
- Although plastic or glass screens can be distinguished by different sensations to the touch, it is recommended that you check your phone model (read online or in your manual) to see what material is appropriate. . [13] X Research Source
- There are new and upcoming phones that are advertised as “self-healing” devices. The plastic of these phones is self-healing to average scratches. If you scratch your phone a lot but want it to stay shiny, maybe you should look into “self-healing” models the next time you shop. [14] X Research Source
Warning
- If you choose to use a strong polish, you may lose the protective coating on the screen. Screen coatings (such as peophobic) reduce friction and increase comfort when using the device. You need to remember this and weigh the pros and cons of screen polishing.
