Just to add I did first try myself with those marble polishing kits you can buy from DIY stores but they didn't work well for me. But the contractor with his polishing machine can do it quickly/properly and give an "as new" finish, just need to find someone who will give you a reasonable price.Beeroclock wrote:This sounds like marble etching, assuming you have marble tiles? We've had this too with young kids. Any acidic liquid like lemon juice, vinegar. And also vomit/reflux due to stomach acids. It reacts with the marble.
You just need to re-polish and it will look as new. When we moved into our place we got everything re-polished and cost was $1,000+. But when we had a similar incident, called the same contractor back just to polish a small section and he did it for $100 or less if I recall correctly.

Something like this can be done on the shower marble walls but on the regular floor it will be visible. Tooth paste is worse than the marble polishing kits Beeroclock mentioned (they basically contain citric acid to gently etch the surface and alumina powder to polish it). Unfortunately I have exactly the same experience as Beeroclock - you can kill yourself doing it. I once spent 5h recovering the tiles (with power tools!) after my wife dropped on them a glass of red wine. The results were very so-so, far away for anything acceptable.QRM wrote:Boot polish works on dark colors, have you tried tooth paste / T-cut for car paint work? or try getting spray fixer from an art shop or hair spray it puts a matt surface layer down but will only be a temporary fix.
Yes, by the images it appears they're tiles with marble etching.Beeroclock wrote:BedokAmerican, suggest you google marble etching and look at the images it throws up. If this is what you have, then from my experience the toothpaste/ baking soda/etc fixes may not suffice, versus a professional polish of the affected area.
5hours! You have some serious staying power, I got a sore arm after 5 mins and concede defeat, call in the pro.x9200 wrote:Something like this can be done on the shower marble walls but on the regular floor it will be visible.
