It can, but keeping the stone wet will reduce friction and help prevent scratches. Rub the stone over the porcelain as lightly as you can while still applying enough pressure to remove any stains or debris. You can also soften any stains or buildup first with vinegar or a cleaning solution so you can rub them away more easily.
