MB-11 Marble Polishing Powder with Microfiber Cloth and Gloves - Spot Polish Water Stains, Rings or Etches to Restore Marble, Travertine, Limestone or Onyx

This is the stuff! I had several water rings/etch marks in my bathroom vanity marble top. I don't normally like to name other priducts but feel compelled in this case --- i tried Lustro Italiano, and with quite a bit of time and effort I had some decent success. I ran out of it and decided to try something else. WOW! Night and day as far as effectiveness. It takes some rubbing, ( follow the instructions) but it's MUCH easier than the other stuff and works better. The vanity top looks better than the day I bought it. All the marks came out and it left a beautiful shine.

This product did an excellent job of removing etching and minor scratched from a marble countertop. Just a little elbow grease and patience is all you need

Removed most of the water marks/stains (from using harsh cleanser) on my quarts counter tops and shower wall. The surface looks much better.

I used CRL in an attempt to remove some hard water spots / etching from the guest bathroom counterrop in my recently purchased home, an apparently very expensive brown marble. Those of you dumb enough to do the same will know what it looked like / how I felt. The MB11 powder made me gag, required a lot of elbow grease and about 3 applications, but it did work, and I am grateful for that. I'd say I spent an hour to get the sink from RUINED to better than it was when I bought the house. When I build up the nerve, I may get a mask and do one last application to make it even betterer. OR I will quit while I am ahead. You all know what I mean.

Good product and compatible with the presentation
