Black Diamond Intensive Cleaner penetrates deep into stone tile and cast concrete to bring dirt and grime to the surface for easy cleaning. Most cleaners only clean the dirt from the surface without touching the stuff that has soaked deeper into the stone. Intensive Cleaner gets rid of what others leave behind without dangerous solvents. This biodegradable formula is safe to use inside or out. This labor saving cleaner starts working on contact and will not harm stone or tile. Size: 32 fl oz.
