I WAS AT MY FATHER'S ESTATE AUCTION YESTERDAY. THIS I CAN TELL YOU WAS ONE OF THE MOST HEART WRENCHING THING I HAVE EVER BEEN THROUGH. IT WAS AS THOUGH MY 46 YEARS OF MEMORIES WERE FOR SALE! OH WELL AT LEAST IT GAVE US A CHANCE TO BUY SOME OF OUR LIFE. I BOUGHT SEVERAL PIECES OF ANTIQUE FURNITURE. ALL WERE 75-100 YEARS OLD.FIRST HOW DO I CLEAN AND POLISH IT? ALSO WHAT DOES THE MARKING RS WITH GERMANY UNDER IT AND A SYMBOL AND A STAR OVER IT MEAN? ALSO HOW DO I CLEAN DARK GRAY MARBLE ON A VICTORIAN STAND? THANK-YOU SAD PA.
