The plaster ceiling in our living room collapsed the other day, unfortunately onto our wood coffee table. The table is made of something called "plantation wood" (fancy Crate & Barrell name for generic dark wood) and has a wax finish. The table has an authentic-looking rough finish with some cracks and bumps and textures. The plaster residue/dust got into a lot of these imperfections and it's hard to get it out with a regular dusting. I've tried using a tooth brush, but the bristles don't seem to be stiff enough to get the job done effectively.
There are also a couple two-inch scrapes where it appears the finish is damaged. Should I be using a very fine steel wool to clean up the table and/or smooth out the scrapes? Is there some other solution or material I could use in addition? Any advice is appreciated.
