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 requires a lot of elbow grease, but if you're willing to put in the time and effort, this product makes old dull marble shine.

This is the absolute worst thing! It absolutely did nothing on my marble table! I’m so upset and I’ve already opened it and tried it 😡 I’m so upset about this! I want my money back! Never ever buy this !

Used in a light cream marble. Very successful in blending out water stains.Also shined up some deeper chemical etches making them far less apparent (ie you have to know they are there and look for them with the light at just the right angle).I was really surprised at how effective this product is.I just wish there was a product for shining a whole area using a polishing machine.

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.

The product worked but the plastic container lid was broken so the cloth, gloves, container and plastic bag were covered with the powder from the can. It was a mess but after cleaning it all up I taped the lid as I needed to use the product right away. So product would get a higher rating but the product was not protected enough in the package. A box would have been better.

This polishing powder is very effective. I was not able to get the marks out of a damaged countertop with it, but after I did that with some polishing pads, I used this powder to shine the dull surface and it worked very well. I applied it by hand with a microfibre cloth and it really didn't take that long at all to get good results.

I had a dull looking bathroom floor from years of heavy traffic and the wrong cleaning products. MB marble polish restored its shiny finish. Thank you

It seems to kind of work but takes way to much effort. I spent several hours trying to fix a bunch of etched spots. They're maybe a bit better, but definitely not gone. It might work better for small spots it of you have a polishing attachment for a drill.
