Linear Rail damaged?

While disassembling my eva 3 i found what's looking like metal shavings on my x axis linear rail. It looks like a coating coming off.

If i move over those shaving very gently with a metal tool, there is a perfectly fine surface under it.

Should i get a new linear rail or is this fixable?

I got this printer a few days ago and it doesn't even have 2h print time.. the other linear rails are not affected.

Not easy to get a picture of the problem. I attached thr best one
