When it comes to cleaning your screen, it's a very simple process. You can use microfiber cloth and Windex. Simply spray Windex onto your cloth first and do a wipe down of your screen when needed. You will not need to do this very often, but once in a while, take a look at your screen. If there's large dust accumulations, you can go ahead and use that method. You can also use a vacuum brush tool to remove the dust from your screen. If you have slight oils because someone maybe have touched the modules without gloves, you can use a microfiber to remove that oil that has been placed on the modules. Do not spray water or liquids directly onto your screen. You'll want to apply liquids to a cloth first before wiping down.
