Now turn the phone off, because you do not want to force a sudden shutdown. Dip the cloth in warm water and squeeze out as much water as you can until the cloth is simply moist, then wipe off the grime and grease from the phone’s surface. Wipe both the front and back, and be gentle when wiping the screen. Speaking of the screen, you might want to remove the screen protector to clean the actual display, and then carefully place it back to avoid those annoying empty-air spots. You might want to look for a case protector as well – the best way to keep your smartphone clean is to prevent it from ever getting dirty. After the warm water scrub, get a disinfectant and wipe the phone with it – one thing you should know is that you have to keep your smartphone germ free. After all, you spend most of the day holding it, and parts of the day sticking it to your ear, and you want to avoid any kinds of bacteria going there.
After that crack open the case – you might want to consult your user manual first, check for manufacturer advice about cleaning the inside, and be careful not to void your warranty. After you successfully open up the case, make use of the cotton buds, dip them into your chosen cleaner and gently start dabbing about the inside. Don’t forget to remove your SIM card and SD card as well so that you don’t damage them in the process. Being gentle is the key here – such devices can be very fragile and you need to take good care of them. When finished wiping, use a dry cloth to soak up any remaining liquid inside, place back the SIM and SD card, put the battery back, and close the case.
Congratulations, now you have a clean smartphone! Now you should focus on keeping it clean since you do not want to repeat this process more often than you should. And you should do it regularly, yes. Once in a month, at least. After that you will not have to worry about dirt being the problem to a broken smartphone.
