2015 Guides On How to Clean Your Dirty Smartphone Screen Like an Engineer.

 In Today's world, Cell Phones have been found to be one of the
 most dirtiest things we regularly touch. Recently, studies shows that
 cell phones have more germs than a toilet seats. Where you surprised? And guess you wouldn't want to rub your palm on a toilet seat. So it's very important to always clean up your smartphone because of the day-to-day
interpersonal relationships we constantly have.
 The materials needed are:
 1. Cotton swabs
 2. Distilled water
 3. Alcohol
 Why do we need them?

1. Cotton Swabs: cotton swabs is easy on Smartphones because
 the shafts won’t be as flimsy as the cheap off brands.
 2. Distilled water: The water that drips out of an Air conditioner(Ac) is distilled and can be used, and this can be used this is for cleaning your screen and
 camera lens. I recommend you get distilled water,
 because it won’t have the chemicals that
 won’t leave a film if it drys.
 3. This is for cleaning
 your keypad and hard plastic.
 Now let's get started.
 Cleaning Your Phone:
 Start by turning off your phone you could do that with any default that came with your phone
 or finding an option in the phone to turn off or swap the
 battery.
 You should also remove any case or cover on your phone if
 you use one.
 If it's within your reach, remove your battery from the phone
 before cleaning.
 'Be careful when removing a screen protector because the
 peeling action can cause cracks to spread'. If you have major
 screen cracks it is recommended you leave the screen
 protector on because it will help keep moisture out of the
 phone and hold the screen together until you can buy a
 replacement.

 If you have a keyboard or keypad start cleaning it with a
 cotton swab dipped in diluted rubbing alcohol. Be careful
 not to rub too hard and not to get any rubbing alcohol
 inside the phone or under the keyboard.
 Next move to the rest of the phone plastics. For large areas
 like the battery cover it is fine to use rubbing alcohol.

 Use
 light pressure when cleaning plastic so you don’t remove
 any rubber coating or clear finish.
 If you have metal trim on your phone, use a water
 dampened cotton swab instead of rubbing alcohol.

 Once the outside is clean, use a dry cotton swab to clean
 out any dust under the battery cover. If you have
 any stubborn areas under the battery cover, use a very small
 amount of distilled water to clean it. Immediately dry any
 parts you clean with water so nothing gets inside the
 phone.

 Dampen a cotton swab with water and clean your camera
 lens and flash using a spinning motion. Once the lens is
 clean quickly dry it with the other side of the cotton swab
 so that water doesn’t dry on the lens.
 Now that the major portions of the phone have been
 cleaned, flip the screen over and dampen your lint free
 microfiber cloth.

 You don’t want the cloth dripping wet; the
 dampness will help remove crusted on streaks.
 Clean the screen in single strokes from the ear piece down to
 the microphone.

 This motion will keep from spreading dirt
 into your ear piece. Don’t use circular motions because this
 can cause circular scratches.
 Be very careful if you have a cracked screen because
 removing a screen protector or wiping the screen with
 pressure can cause the crack to spread.

 You may also want
 to forgo the damp cloth and just use a dry one to prevent
 any moisture from getting under the screen.
 Some low end and older phones have plastic screens which
 can easily scratch.

 Make sure you use light pressure when
 cleaning your screen to stop scratches from forming. Most
 new Android phones and iPhones have hardened glass
 screens which won’t scratch as easily.

 If you removed your screen protector, follow the directions
 that came with the protector to apply a new one after
 cleaning.
 If you have an iPhone 4, remember that the front and back
 are made of glass so clean both sides the same way.
 The iPhone 3GS, iPhone 4, iPad, Google Nexus S, and quite a
 few other phones have an oleophobic (literally meaning
 “fear of oil”) coating which repels oil from your hands and
 face. This coating will wear over time so make sure you
 don’t rub too hard or use rubbing alcohol or you might
 speed up the wear process.
 Give the phone a few minutes to dry, then re-assemble and
 turn it back on. You should now have a clean phone without
 those nasty germs.

 Clean Your Case:
 If you use a plastic phone cover/case use diluted
 alcohol and cotton swabs to clean the inside and outside.
 Allow the case air dry before putting it back on the phone.
 If you use a leather case or pouch you can use leather
 cleaner designed to clean and moisturize leather, for better result.
