Thanks

IF the counter tops are "Solid Surface" (i.e. quartz, or Corian), the blemished area can be wet sanded to eliminate the blemish then polished to restore luster. All of which must be done carefully. Anything other than solid surface, leave it alone.
Good luck!

Thanks much

Your first pic shows a textured top likely Corian type??? Looks to be an actual indentation made. I would contact manufacturer. Not much chance of getting that to look good with the textured top. I say defect in the material.

Second pic try using "BioClean" AMAZON type in "Bio Clean: Eco Friendly Hard Water Stain Remover" GREAT product!!!

get a professional to look at it and give his/her opinion. as they say, "don't try this at home. "
