What should I clean my Nikon with?

I recently bought a Nikon D500 and my screen/lens are bit dirty. I just wanna know what's the best way to clean them without getting my lens/screen scratched?

A micro fiber lens cleaning cloth. Available where ever cameras are sold. NO LIQUIDS!

A microfiber cloth will be fine for the lens. If that doesn't do it then buy a good liquid cleaner (http://www.calumetphoto.com/eng/product/calumet_optical_glass_cleaning_kit/cq1020) for example.

The lcd on the back can get the same treatment, if dry cleaning is not enough then a good quality screen cleaner can help.
