MB Stone MB-11® Touch-Up Etch Remover Marble Polishing Powder for Light to Neutral Colored Calsite Based Stone, Light to Medium Etches Only, not for Matte or Dark Stone, 8 oz Can

I have a white marble bathroom countertop and two beige bathroom countertops. All three were in bad shape, especially around the sinks. Etchings from makeup, toothpaste, various soap products, and spilled CLR made these countertops look pretty bad. Other than calling in the professionals and spending at least $600 to clean up the mess, I decided to give MB Stone MB-11 a try. The bad news is it takes a lot of rubbing using significant force to remove the stains on the countertops. The etching made by the CLR were the hardest to remove. It took multiple times applying the compound to a moist rag and rubbing the etching to remove the stains. The good news is this product saved the day. Following the directions, I was able to remove all the etchings and made the countertops look almost new. It took me the better part of 5 hours to do all three countertops, but it was well worth the effort. I did buy this product from Amazon's warehouse deal for $31, which was a great value. The next project is to seal the countertops, which is needed to prevent future stains. I would highly recommend MB-11 for a DIY project. It is not messy and doesn't require any buffing equipment (just elbow grease). It really works, but it is time-consuming, and I guarantee your hands and fingers will be sore when you are done. The powder goes a long way, I still have 2/3rds of the jar left after completing my project. I have attached a before and after picture of one of the countertops. I would recommend MB-11 and would purchase it again.

I had a terrible lemonade spill on my travertine tile floors which resulted in two very noticeable, dull etch marks. I was skeptical about any product that could fix acid damage, but I decided to try MB Stone MB-11® Touch-Up Etch Remover. I applied it to the etched areas exactly as directed. The difference after the first treatment was significant! The worst of the dullness is gone, and the marks are definitely less noticeable. While the damage isn't totally vanished, I believe a second treatment will get it much closer to perfect. If you have light etching on polished stone like travertine, this is absolutely worth the investment before calling a professional. It improved the area enough that I can easily live with it, and I'm optimistic a second round will finish the job. Highly recommended for DIY etch removal.

the product worked great. For my situation I didn’t need to rub particularly hard it was a moderate back and forth rubbing about ten times and then a circular motion. Remember to feather your pressure as you get to the end of the affected area if you are not doing the entire surface. Then I sprayed lightly with water and polished with a dry cloth. I am so pleased I thought I was going to have to call a service. Two of my bathroom vanities are back to looking fantastic. I bought the 1oz container and hardly used any product for the two countertops. Less is more in this case.

Did not work at all on the etch marks on my white Cararra marble breakfast table. It ended up being a very expensive trial product. I have most of the bottle left and there's no option to return it. I wish they offered this product in smaller bottles so you didn't have to spend so much $$ just to find out that it doesn't work on your piece.

This stuff seems to work great! It does take a lot of buffing but it did start removing the light water mark etchings on our bathroom marble counters. I also tried it on our travertine floor where someone spilt something that left a dull spot. I was able to carefully scrub the dull spot and blend it right in with the rest of the travertine finish.

This product helped a little on our marble countertop but didn't solve the problem. We were trying to fix an etched ring from vinegar. Seemed like we needed more water to make a paste than the instructions described.

My marblelite counters were a mess from several years of being unsealed. Chemicals, water, contact lens solution... we had it all. I finally tried this and it cleared up more than 50% of the stains. The others have become less visible in direct light. I used a car detailing drill brush attachment and laid into the paste for several applications (close to 45 minutes total). I imagine that newer, surface level stains could be removed by hand as they describe.

We've been to every granite shop and several different home improvement stores looking for a product that would remove the etching from our granite countertops in our bathroom. Some knucklehead from a cleaning company used toilet-bowl cleaner to clean the surface and unsurprisingly it ate away the seal on the granite and etched the finish. Lowes & Home Depot both told us to buy new granite. The "Helpful Hardware Folks" were not particularly helpful, selling us liquid cleaners that didn't come close to doing the job (don't waste your money). The granite stores all told us "you need new granite." But my wife was resolute that if the granite people polished the stone, there must be a way for us to polish it back to its original state. So she found this product. I thought it was pricey, but as compared to buying two $450 slabs of granite to replace the ruined pieces, it was worth a try. There is a YouTube video on how to use this (just search for "MB11 Touch Up" on YouTube) that shows the use of this product on a piece of marble. We followed these directions explicitly and we couldn't believe our eyes. No etching. You can't tell the polished pieces of granite from brand new now. People who sell granite do not want you to know about this great product, which is why they don't stock it I'm sure. But this stuff is a life-saver and worth every penny. Note, some elbow grease is required to make this product work, but again, I'd put forth the effort again to avoid paying for new rock.

In a cleaning frenzy I left a bottle of bleach on a marbled surface, I couldn’t un-see it and thought I’d ruined the surface with this etch. It was driving me nuts. Until I did a little research and discovered this miracle product. With very little effort it had vanished. 100% worth every cent. Please don’t be discouraged by negative reviews. THIS ABSOLUTELY WORKS! See my before and after pic. Just purchased a second tub for relatives who have tried everything else and have been quoted thousand$ for repair jobs from professionals. My tip…. Do it yourself and don’t get scammed into thinking it’s irreparable. Thank you to whoever invented this. Your degree was worth it. ONE VERY HAPPY AND RELIEVED CUSTOMER HERE 🙌🏻

This stuff SAVED my new white marble bathroom vanity. I stupidly used windex and Lysol to give it a wipe down, probably more than once, and notice a couple weeks ago it was dull looking with what looked like dried up water spots. So I took a damp cloth and wiped again, it did not shine and those “water spots” remained. After a deep dive on google a realized I “etched” the surface with cleaning products. I know bare minimum about any of this (clearly) but read some reviews and instructions on a few products and this one seemed the easiest and also promising. Well it was easy, used it according to directions but I used a regular cloth because I don’t have a microfibre one and it worked beautifully anyway. My counter is now shiny and “spot” free. I’m going to apply a sealer now and buy a pH neutral cleaner to use on it from now on! I attached pictures (it’s hard with all white) to show the dullness and “spots” before and shiny and new after.

I have watched a few Youtube etch stain removal video before buying the product. It works really well! For larger stain, you might have to work a few rounds to remove it flawlessly. Overall, very satisfied with the product! Remember to keep your gloves on while scrubbing, I was too excited with the result and forget to put my glove back after feeling the smooth surface, I had accidentally continue to scrub without my glove and my fingers felt pretty itchy after that. The etch remover is awesome, just don't do silly thing like me.

It works. My marble bench got a small etch. I used this product to touch up the marble. It worked. The itch has been removed.

I was sceptical that this produce would work as i had etch marks from orange juice. To my surprise, it worked after just 10 minutes of application and cleaning. It does leave a residue that will go away after cleaning the marble floor a few times.
