Visually repair a scratched surface of PLA

[Neukyhm 2]

So I have finished printing a very big piece. I had trouble separating it from the cristal base, I used a spatula for that, but I scratched the surface:

 

Is there anything I can do to fix it? I have thought about heating that area through a piece of glass.

Heating is not so good, it will deform quicker than you can fix the surface.

I would sand it a little bit and if you use 1000 or 2000 in the end, it should get quite nice.

Sand it down and put a touch of moisturiser on it if it goes lighter. Colorfabb sands quite well not sure what filament you are using?

Yup I second the moisturiser. I use Johnsons baby oil, a lot cheaper than getting caught with the lady's designer moisturiser ?
