Mira Dust polishing powder was designed to enhance the shine of natural stone and terrazzo. Mira Dust will remove light scratches, water ring and acid etch marks. Mira Dust does not change the surface composition of the stone. Mira Dust is safe and easy to use, and, unlike most traditional polishing powders, does not contain oxalic acid. Unlike recrystallization, Mira Dust does not alter the surface composition of the stone. Great for on-going maintenance or spot repairs. 1 lb. Container. Miracle Sealants
