S9 Fingerprint Scanner help

[Sami444]

Yestarday, I have noticed some sort of bluish blackish inc coming onto my fingerprint scanner of my Samsung Galaxy S9. I tried wiping it off with wipes, however, it doesnt seem to come off. If someone has any explanation regarding this, please reply to this post. Thank you.
