Amish Dining Table

Hi,
We recently purchased a dining room table from you. Just wanted to thank you for the wonderful job you did.  We really love it.  I was concerned about the care for it.  Do we need to polish it to keep it looking like new. Or do we just clean it with a damp cloth.  Not really sure how to care for it.  Any help would be appreciated.

Thanks again
