Looked at a 3 month old marble shower installation (light emperador) with 11&#39; high walls installed with a sanded grout.  Everything above the 6&#39; level has a heavy dried sand grit on the marble face and lots of heavy streaks running down the face as well, bottom 6&#39; not much better but no streaking and less sand grit present.  Looks like a very poor clean up job.  Testing with alkaline cleaner was negative.  Any suggestions on how to remove and salvage?  Homeowner is NOT happy with contractor, and looking for solution short of tear down.<div>
