What is the best brandNo chemicals or solvents required. Just a microfiber cloth and moisture from your breath, if required. If you eat while using your phone you might want to "slightly" dampen the corner of your cloth.
I also like to take my case off very few weeks or so to remove any accumulated grit that can act as an abrasive if caught between your phone and case. It can and will actually "scuff" the finish.
