I bought an matured marble top coffee table. The marble is not polished. How can I bring back it to shine?

Bissel Pro Heat Steam Cleaner?
Answers:    Put a spray finish of laquer on it. You have to let it dry for 2 days though. You didn't ask for prompt, you asked how to get it to shine. Windex you have to do adjectives the time, laquer is once every couple of years.
You can get one of those car polishers really cheap at the sports car parts place or tool shows ($20) and polish it that way, as an alternative to the laquer but it is hard work.
Wall Power outlet is out of use any...
verbs it with a warm rug, consequently dry it; spray some windex and dray it again.it will shine!.
