Q:

How do you clean your phone screen of breakout causing build up regularly?

I would first like to clarify that I believe my question is not a dupe of: How can I remove skin oil from my phone's screen? as I am specifically asking about a sensible solution to help prevent breakouts.
I have read that you should wipe down your phone twice a day using anti-bac wipes if you are suffering from breakouts on your cheeks. 
However, I don't like the idea of being that wasteful as these wipes are not usually bio-degradable. Using a homemade solution on a cloth is also not a viable option as I need to keep it at my desk at work.
I know you can buy bio-degradable anti-bac wipes but they are not often made for use on a phone so are much too large - which again seems wasteful.
Does anyone have any ingenious, cost and environmental efficient, solutions?

A:

In the spirit of an XY Problem
, let me offer an alternative solution:
You want to prevent breakouts caused by bacteria on the phone being transferred to your skin 1. The answer: Don’t let the phone touch your skin. 
Instead of holding the device up to your ear, use a headset (or the loudspeaker, if privacy isn’t an issue) for your phone conversations. Bonus: you may even free your hand, if you are sitting at your desk.
Cost: 
Maybe a headset was part of your phone package, otherwise it’s an initial investment without recurring costs.
And of course don’t prop up your head in your hand during the call and in general don’t touch your skin with your hands unless necessary.

1 And I am not arguing with the premise - you don’t want to transfer anything, independent of the question whether it may or may not trigger breakouts. That’s enough for me.

A:

You need 

a disinfectant (rubbing alcohol will do, or some other sanitizing liquid), 
a way to apply it and 
a way to remove it again.

Either use a spray bottle (reusable, use what you have around) to spray the screen, then wipe it off with a piece of cloth (lint-free, washable) or tissue paper (although less sustainable, but at least biodegradable), or moisten the cloth with the liquid and wipe the screen.
Cost: minimal. 
A bottle of rubbing alcohol is cheap (a dedicated sanitizer may or may not be more expensive, but you don’t need a “kill-even-the-worst-germs-and-fungi” substance to wipe down a hard and smooth surface like a phone screen anyway) and you probably have a washable cleaning cloth around - in a pinch, recycle some soft cotton clothing, like a t-shirt, or grab a dishcloth.
