MB Stone MB-11® Touch-Up Etch Remover Marble Polishing Powder for Light to Medium Etches Only, use with Neutral Colored Calcite-Based, 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.

This stuff works! We are in a rental and the previous tenants took poor care of the marble countertops. Alltough some etching didn’t budge, it did a great job taking off some of it. Our counters are sparkling! Beware smell is strong and it did make me a little lightheaded. Open the window when using, and wear a mask.

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.

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.

I used this product on my bathroom sink (white marble) and it worked really well. I accidentally spilt some apple cider vinegar on the sink and it etched the marble pretty bad (it went from polished to dull spots that would not come out). You have to rub it in fairly well to get the polished look back but it did work. It looks 100 times better than before. It's not 100% perfect though: it will leave slight buff marks behind, which I believe is the powdery substance interacting with your original smooth marble finish (keep in mind this stuff is for buffing out the dull marble to get it glossy again) and so it's nothing huge or significant that you will notice, it's just barely there. I'm glad I bought this stuff because the wife would have killed me if she had seen it (I managed to buff it out and tell her afterward! Lol...Thank God for two day shipping!)

Works incredibly well on polished marble, works okay on honed as well even though it's not supposed to be as good for that I think

So easy to use and completely removed the etching from cat vomit. Have also used their stain reeper for shampoo drip on shower wall..Completely removed it as well. I have a newly remodeled home with opal marble..very porous.. called MB stone and they told me exactly what to do. Great products!

This is just about perfect as far as polishing compounds go for polished light colored natural marble. It is not a magic bullet, this is a chemical that does the job for you - it’s a compound that requires real elbow grease and some degree of technique to do a job that otherwise can’t be done. It removed a hazy circle from an area that was polished with a compound that was too abrasive in a way none of the other four items I tried could. It takes effort and maybe even a little practice, but if you want to remove etch marks, haze or just restore a brilliant shine to polished natural marble it’s worth the money.

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 🙌🏻

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.

I was skeptical about this product because I tried basically everything to remove etched stains from my marble countertop and nothing worked. I think I didn’t follow the instructions for this product correctly at first and I even requested a refund. But then I tried again and followed the instructions precisely and it does work like a miracle!!!! It’s unbelievable! My marbles countertop looks shiny and better than ever! (Just a tip. Do not use a soda paste to remove the etchings as Google recommends. It will make it worse).

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.
