reddit handles code pasting weirdly and I don't know if it highlights code so here is pastebin to my ifIsEven generator.

have fun looking into this poorly but at least man-made code, that generates even worse code.

(previous 2 versions on pastebin named exactly the same are older and weren't fully working and were not formatted as I wanted them to be.)

I saw weird gray stains appear on the tool’s black coating and it just looks like some dirt to clean out but nothing is working soap water isopropyl alcohol 85% and 99.5% ordinary pencil rubber.

Is it just damaged like under the diamond file when it rubs against it etc and I should just leave it or I don’t know how to clean it and that’s all?

Also how do I clean diamond file it’s troublesome to get everything out.
