不要使用磨料厨房清洁剂，因为它们将触及表面而伤害到它。

Do not use abrasive kitchen cleaners, as they will scratch the surface.

这个方法非常有效，因为玻璃在从软变硬的过程中并没有触及任何物体的表面，因而在经过“火抛光”处理后能保持完美无瑕。

This method was very effective as the glass had not touched any surfaces between being soft and becoming hard, so it stayed perfectly unblemished, with a "fire finish".
