I purchased a new mahogany door. A new painter stained it and left brush marks! Please help, how can I remove these?

The painter told me that brush marks are "easy to remove" by rubbing a soft cloth with mineral spirits. I am not having luck using this method (old white dishcloth with odorless mineral spirits) Please help me, my new door looks awful and the painter left us high and dry after I complained about this and other issues
