Minor Scratches

• If you want to get rid of minor scratches on the body, or case, of your iPhone, you will need a microfiber cloth and a mildly abrasive cleaner, such as toothpaste, Brasso or iDrops. You will only need a small amount of these cleaners. If you have only a few minor scratches, rub the cleaner over those spots alone; otherwise, rub the cleaner over the whole body of the phone, being sure to avoid the screen. Buff the scratches gently until they disappear, but take care not to remove the iPhone's outer scratch-resistant coating.
  
  

Deep Scratches

• If a scratch penetrates the iPhone's outer scratch-resistant coating, you will not be able to remove it with a simple cleaner. Removing these scratches requires a complicated sanding process that actually removes the entire outer coating. A combination of wet-sanding and dry-sanding blast away everything on the case of the iPhone, including the Apple logo and the writing beneath it. You can send your phone to a specialist for this process, but it may be more economical simply to purchase a case.
  
  

Screen Scratches

• If you ever scratch your iPhone's screen, you will probably not be able to fix it. Rather, you will have to have the screen entirely replaced, and this is almost as costly as purchasing a new phone. The screen is actually a complex layering of special materials designed to detect and transmit the electrical current of your touch, so you can't simply fill in the scratch or buff it out. These materials are also very difficult to manufacture, which is why replacing them is so costly. Some users report success by rubbing the screen with sandpaper, but you should only attempt this at your own risk. Fortunately, the screen is made of very hard glass, so it cannot scratch easily.
  
  

Prevention

• The best way to prevent scratches is to put your iPhone in a hard, protective case. A hard case will also protect your iPhone from harm if it is ever dropped, and some will even protect the device from water damage.
  
  To protect your screen, you can purchase a special clear film that adheres to the surface and transmits your touch through to the actual screen. This film is also fingerprint resistant, so it can keep your iPhone cleaner.
