The grout sealer (I forget the brand) says to clean with some product before sealing. I don’t have any of the product, and we are just doing 1/16″ grout lines on 12 X 12 tile in a little entry way and powder room. Is it really necessary to clean the grout? What is it accomplishing?

If you don't clean it (i) whatever dirt/stains are there now will just be sealed in place and (ii) the sealer might not cover properly, e.g., if there are oily spots.
Just use a good detergent, elbow grease and rinse well.
With my mouth I will give great thanks to the Lord; I will praise Him in the midst of the throng. For He stands at the right hand of the needy, to save them from those who would condemn them to death.

sounds like this is new work, so avoid the detergents or chemicals that are non-proprietary to the sealer manufacturer just pull a cleanup w water and a grout sponge, get all grout haze off allow to dry thoroughly before using a good sealer
