BMC M1-300 Polishing Powder for Marble and Limestone, 300 g Bag, for Treating Dull, Light Corrosion Stains on Mirror-Polished Surfaces. for Manual Application

I am quite pleased with this polishing powder. It works great. Also I am very impressed with the high gloss shine.

It is acidic powder so it can smooth the surface of the dull marble and makes it look shiny again. It works at our dull marble countertop. You need to use buffering pad to really buffer this powder on the countertop.

I’m so happy to see this product on Amazon! I rent and my kitchen marble countertops are covered in water stains, acidic stains and anything else you can imagine. This product is the only thing that can help remove those things and polished marble to a shiny finish. You do have to put some effort into polishing and it can get messy since if you use a buffer, it will throw the powder and little pebbles around but, it works. The only thing is that you have to then seal the marble to avoid future stains, which, in my case, I was unable to do since I did not yet find a good seal.

I used a car buffer and rubbed this over marble stains that were on a black bathroom vanity top that is real marble and it took some time and I made a mess slinging cleaner on the walls that had to be wiped off but it was easy and took a little time to polish it out but totally worth the cost of the product and effort. Buy this if you have marble that you paid a fortune for and it looks kind of crappy.
