I just did a tile and grout cleaning job and in the kitchen by the dish washer there was about 6 tiles that have been changed out. There was no visible water lines in the tile before cleaning but onlly in the tile that was changed out there is water marks after cleaning. I have not gone back to see if it dried out and disappeared yet. I have only seen this happen on mexican tile. I useed extreme carpet pre spray ph of 10 and some oxy booster. I have cleaned 100's of jobs with this same pre spray. Has anyone else had this happen? thanks Kyle
