This product is made of natural rubber and emery by a special foaming process. It can remove the scratches on the surface of the frets and quickly remove the oxide on the surface of the frets and strings. It is a simple and fast polishing tool. The elastic polishing rubber can effectively fit the frets and strings and reduce the damage caused to the fingerboard and strings when used. At the same time, it can be cut into different shapes according to the actual situation, which is convenient for grinding and polishing different metal parts.

品丝抛光使用方法：先在品丝两侧用胶纸粘贴以保护指板，然后使用抛光橡皮对品丝进行打磨抛光，可根据不同的划痕与氧化程度，使用不同的数值进行对应的操作。数值越大，抛光出来的效果越细腻与光亮。

Frets polishing instruction: put tape on both sides of the frets to protect the fingerboard first, and then use the polishing rubber to polish the frets. Different grit number of the polish rubbers can be used for corresponding operations according to different scratches and oxidation. The larger grit number the finer and brighter polished effect will be.

琴弦清洁使用方法：松开琴弦，然后使用抛光橡皮将生锈或者氧化的琴弦进行轻轻打磨，使锈迹或氧化层脱落；当抛光橡皮使琴弦回复本色后可用防锈与润滑油进行上油保护，达到持久的保护效果。

Strings cleaning instruction: loose the strings, and then use polishing rubber to polish the rusty or oxidized strings gently, so that the rust or oxide layer will fall off. After removing the rust or oxide layer from the strings, put on rustproof and lubricating oil can make the protection effect last longer.

使用时抛光橡皮时，琴弦表面的锈迹或氧化层会与抛光橡皮一起脱落，清洁干净即可，不会损伤琴弦。可视琴弦的锈迹或氧化程度来选择抛光橡皮的数值：越严重的锈迹或氧化层可选择数值越小的抛光橡皮，反之亦然。

Different grit numbers of the polish rubbers can be selected according to the difference of the strings rust or oxidation condition. The more serious rust or oxidation, the smaller grit number of polishing rubber can be selected, and vice versa.
