hello and welcome the forums.......The microban stuff is fantastic stuff for w/tops as well but isn,t fully water/stain proof....
If you feel a bit more ambitious and want a fully stainproof grouting job then you can try this...quite easy to work with compared to the older epoxy types...

tile grout specifically formulated to resist chemical attack and to provide a durable, abrasion-resistant, waterproof finish.
