Therefore, this article will introduce some iPhone dust removal tips for you to easily and effectively remove dust and dirt, so that your iPhone can be restored to a new state.I. Use a soft brush to clean the screen. The screen of the iPhone is an important part of the mobile phone and one of the most easily contaminated parts. In order to keep the screen clean, we can choose to gently wipe the screen with a soft uniform brush to remove dust and dirt. When buying a brush, it is recommended to choose a brush with dense capillary, moderate softness and hardness. Please do not use a brush that is too hard and irritating to clean the mobile phone screen. II. Use an eraser to clean up the key areas. If the iPhone has been used for a long time, it is easy to accumulate dust in the headset hole, charging interface, volume button and other key areas. At this time, we can use an eraser to clean up these areas, remove dust and debris, and make the iPhone vibrant. The eraser is soft and will not cause harm to the mobile phone. At the same time, it can effectively remove sporadic stains.III. Use tape to clean the mobile phone frame. The iPhone frame is easy to be contaminated, and many people only clean the front and rear panels of the mobile phone. However, the dust on the frame will also affect the beauty of the mobile phone, and even more affect the feel. Therefore, we can bend the transparent tape into a strip and brush it back and forth along the frame of the mobile phone to remove the dust and small debris in the frame. When cleaning with tape, keep its stickiness to avoid falling off during the cleaning process. IV. Use a vacuum cleaner to remove dust. For those deeper and more difficult-to-reach locations, we can use a vacuum cleaner to clean and remove dust. But before vacuuming, please turn off the mobile phone and remove the battery to ensure that the mobile phone will not be damaged. When using the vacuum cleaner, manually adjust the suction size and choose a smaller opening of the suction mouth to get closer to the gap and depth of the mobile phone. Before vacuuming, please gently scrape off the accumulated dust with thin chopsticks and other tools, and then vacuum.V.
