it works...and it works well.
the stone polish is a product that will rejuvinate the color and the luster of a granite countertop, especially if the home owner hasn't done much to it for a while. it will make it smooth , slightly darker and shiner. and btw it is also a
sealer, so they don't have to worry about resealing it evey year or so.
the way we sell it is to compare it to Pledge for wood, the only thing is this is for granite...
they wouldn't use it every day but just every couple of weeks (if they use the kitchen to eat and cook) or right before a visit of sombody that they are willing to impress with their new countertop.
for every other use they will use the "daily" cleaner.
