Well, I'd just clean it well with water until you figure out what the material is. Then someone could probably advise about the best course of action.

Is the vanity still on Wayfair so you can see what they say it is made from?

It must have talc in it. Marble etches because acid erodes talc. The etch is not a stain it is a structural change. Tin oxide can sometimes repolish etched spots but honestly the ring is just one of soon to be many. Soaps, skin tonics even some toothpastes contain acid and will too etch marbles. Call it patina and think of your beautiful daughter when you see it instead of seeing it as an imperfection.

Is it marble? If so, it etches. I have carrara on my guest bath vanity and it has plenty of etches, visible only in certain light. Other than that it's still beautiful and has an incomparable feel. I'm gentle with mine but I haven't found anything non destructive that takes out etches. Be glad she didn't drip toilet bowl cleaner on it. Ask me how I know. :(

I'm sorry about the etching eld, and I shouldn't be laughing, but reread your third paragraph.

I actually looked it up Bunny, sincerely wondering if it were an unfamiliar countertop material. It is not, I found. Still curious what Eld meant to type?

I have a honed aged marble on one of my counter tops. The aged aspect in this case means it is not shiny and not perfectly flat (intentionally).

Early in my stewardship of this lovely stone, I had tomatoes from my garden in a colander. I didn't notice one was bruised, and it dripped (acidic) tomato juices onto the counter. I have a partial ring. I am not sure why, but over time it does in fact fade. I need to look for it. HTH

Yikes. I see I can’t edit. I of course meant white, Bunny!

I have to find the original order so I can call to see if I can find out what it is.

i wonder if I can get someone here to polish it.

How come we can’t edit a thread you start?

if it's marble there's a special paste for it..polishes etches out..as long as the marble is not black or other kinds of dark one.

it works. if you want I can check how it's called, ..let me know..got it on Amazon I think

if it's cultured marble I'm not sure

( I thought "shine" btw. "Wanted shine"))

no suggestion but laughing at your typo. Now that would be an interesting counter material. Maybe Barkeepers Friend?

I have a white marble vanity top in my master. It etches. I've used this product with great success. It's a powder that you mix with water. I just used a clean cloth and rubbed it on(with gloves of course). Wait a few minutes and rubbed it off. The etches come out and the marble looks like new. You don't even need to rub very hard. I also used it on a tiny spot on my polished quartzite kitchen counter.

yes. mine is by MB Stone Care too. But it's called just "marble polishing powder". I'm pretty sure it's same product that they named differently. The description is exact same.

Can't you look on Wayfair and see what the countertop is? Don't do anything until you know.

You only have a short time to edit an original post (maybe 30 min?) compared to editing comments on someone else's post. I thought you meant you wanted "to shite" when you saw it. I had to google that and figured it was the perfect word for how I would have felt!.
