Dirt, grit, and sand inside phone cases can cause scratches
While plastic cases are meant to protect your phone from scratches, dirt, grit, and sand inside phone cases can cause scratches on your phone. This happens when debris like sand, dust, or dirt gets trapped inside the case and rubs against the phone, causing scratches over time. To prevent this, it is important to regularly clean your phone case and the phone itself.
It is recommended to take your phone out of its case and clean it at least once a month, or more frequently if you spend a lot of time outdoors or keep your phone in a bag with other items. You can use a microfiber cloth to gently wipe down your phone and remove any smudges or specks. For tougher dirt or sticky substances, you can dampen the cloth with a little water and gently work out the spots.
Similarly, you can wash most phone cases with a light dish soap solution to remove any built-up dirt, grit, or sand. If your case is difficult to take off, you may need to do this less frequently, but regular cleaning will help prevent scratches on your phone caused by trapped debris.
In addition to regular cleaning, you can also opt for phone cases that are specifically designed to keep out dirt, grit, and sand. Cases like Lifeproof or Otterbox are known for their ability to seal out debris and provide a higher level of protection for your phone. By investing in a high-quality case and maintaining a regular cleaning routine, you can help keep your phone looking like new and prevent scratches caused by trapped dirt, grit, or sand.

Phone cases do not actively scratch phones
Phone cases are designed to protect your phone from scratches, cracks, and fall damage. However, some people have reported that their phones have been scratched by their cases. So, do phone cases actively scratch phones? The answer is no—phone cases do not actively scratch phones.
Phone cases can contribute to scratches on your phone, but only when dirt, grit, sand, or other grime gets inside the case. Over time, small bits of dust and dirt can get trapped inside your phone case, and when your phone moves inside the case, the dirt can rub against the phone and cause scratches. Additionally, if your phone case is made of a soft material that can be easily scratched, such as silicone or leather, dirt and dust can get trapped in the scratches and cause scratches on your phone.
To avoid scratches on your phone, it is important to clean your phone case regularly. Wipe down your phone case with a lint-free cloth every few weeks to remove any dirt, dust, or grime that may have accumulated. If you frequently take your phone to the beach or engage in outdoor activities, it is especially important to wipe down your phone case regularly. Allow your phone case to dry completely before putting it back on your phone to avoid trapping moisture inside the case.
By taking proper care of your phone case and cleaning it regularly, you can help prevent scratches on your phone and maintain the pristine condition of your device.

Phone cases can be cleaned to prevent scratches
Phone cases can get scratched over time, even the most durable ones. This can expose your phone to damage and ruin its appearance. Scratches can occur when small grains of dirt get into the gaps between the phone and the case.
In addition to cleaning, there are other ways to prevent scratches on your phone case. One way is to choose a scratch-resistant case made from materials like polycarbonate, TPU, or silicone, which offer durability and resistance to scratches. You can also use a pouch or sleeve specifically designed to store and protect your phone case, providing an extra layer of protection from other objects that could cause scratches. It is also recommended to avoid placing your phone case on rough surfaces or keeping it in the same place as your keys to prevent unnecessary scratches.
By combining regular cleaning with other preventative measures, you can effectively protect your phone case from scratches and maintain its appearance and longevity.

Vinyl skins can be used to prevent scratches
While plastic cases are a common way to protect your phone from scratches, they can sometimes cause scratches themselves. Small grains of dirt can get into the gaps between the phone and the case, and the case can then scratch the phone.
Liquid Armor, sold by Dynaflo, is another option for protecting your phone from scratches. It promises to protect your screen without the bubbles or creases that can sometimes plague vinyl protectors. It forms a "nano-shield" that absorbs scratches.
If you want to stick with a plastic case, there are a few things you can do to prevent scratches. Firstly, make sure to clean your phone cover regularly to avoid scratches caused by dirt and debris. You can also opt for a soft TPU case with a hard plastic band on the outside, which may be less likely to scratch your phone than a case made of hard plastic.

Some cases are more prone to scratching than others
Some phone case materials are more prone to scratching than others. The susceptibility of a material to scratches depends on its hardness. Softer materials like plastic, wood, or rubber are more susceptible to scratches when exposed to harder objects. On the other hand, harder materials like metal, glass, or ceramics tend to resist scratches. The Mohs hardness scale is often used to quantify this property, ranking materials based on their ability to withstand abrasion.
For example, the original Apple bumper case for the iPhone 4 and 4s had a hard plastic interior that scratched the phone. Similarly, the Otterbox case has been known to cause scratching on phones, leaving micro-scratches on the bezel of a Motorola Droid and the silver sides of an iPhone.
To avoid scratching your phone, it is recommended to clean your phone cover regularly and ensure no dirt or debris gets trapped between the phone and the case, as this can also cause scratches over time.
