Dear Adam:
Wow, it didn't clean not even with the “magic” cleaner??... Maybe you should have tried the “miracle” cleaner instead!...

Sorry, but I could not resist.
Vomit is acidic and acid corrodes marble and any other calcite-based rock. Which means that you have a severe etching (corrosion) on your stone surface that, of course, can't be cleaned off. It is like a shallow chemical scratch, and you could not certainly clean a scratch off, could you? In other words, it is a serious surface damaged that can only be repaired.
How?
At the end of the day it is not a big deal, but your only option is to hire a bona fide stone restoration contractor who will lightly grind (hone) and then re-polish your stone.
Now, you'd better watch out! I consider stone refinishing as the very pinnacle of all the activities related to stone from a professional point of view. Unfortunately, there are a lot of quacks on the loose out there! You get one of those, and you may even have to kiss your stone bye-bye!
How could you tell a champ from a chomp? Could you trust the recommendation of your local stone distributor, or contractor, or your interior decorator? Hardly!
We have available a very comprehensive article on how to select a bona fide stone restoration contractor, which will give you all the intelligence you need to make a competent choice. It does carry a small price tag, and you can order it by logging on the Educational Literature section 0f our website at:
http://www.mbstone.com/literature/literature.htm. It's available in pay-per-download format and I consider it a cheap “insurance premium” to pay when there are thousands of $ involved! Not to mention the little and much needed support you'd be giving to the cause – YOUR cause, since every single penny of the cost of the article will be used to support it.
