Stuart,

As long as it's not an epoxy grout, I typically use Stone Pro Stone and Glass Scrub with a hogs pad and Makita. In most cases, 2 quick passes and done. Works great.

A recently installed shower wall has a grout haze on it. The haze is not evenly distributed across the marble tiles. It is thicker in some areas and thinner in other areas.  To remove the haze, in the past,  we have done this mechanically with DIP’s, however I am looking for a chemical solution in order not to alter the factory polish of the stone.  It may have to be a combination of mechanical and chemical process. Any ideas?
