Screen scratches

So after a year of usage, my M6 has shown wearing, and scratches on the screen. Are there any remedies to remove or treat the scratches? I know theres something like this for glasses, but I'm not sure if it works or not.

Hello there! Using the search function, I found my old posts about how to remove scratches:
how to remove scratches?

I also wrote a good amount of stuff in that thread on how to prevent scratches. I definitely recommend you consider taking my advice if you plan on getting a Meizu M8 device.

In case you didn't catch it.

Either way, what about the metal back? Anything to remove scratches off that?
