Discoloration can come from a few different sources. To each type of monster, a different poison.

Stains are one of the most common kinds of discoloration. They are caused by the absorption of materials into the pores of the stone causing it to have a different color from the rest of the countertop. They can either come from spills or prolonged exposure to chemicals. The good news is, once the staining agent is removed, the stain on the granite countertop is gone too.

Etches are a whole different story altogether. They are not caused by the absorption of material but rather a change in the chemical composition of the surface of the rock. They do not disappear once you remove the chemical or fixed by common granite stain removers. Most of the time it requires professional help. Etches are commonly caused by exposure to highly acidic or alkaline chemicals that cause discoloration. You will need to assess if the damage is on the finish or has reached the stone itself.
