1. 定期清洁：橡皮擦在使用过程中会积累一些笔迹碎屑和灰尘，定期清洁可以保持其良好的使用效果。可以用橡皮擦清洁器或者用软布轻轻擦拭。 2. 涂抹润滑油：在橡皮擦表面涂抹一些润滑油，可以减少摩擦力，延长使用寿命。但注意不要使用过多，以免弄脏纸张。 3. 更换新的橡皮擦：如果发现橡皮擦表面磨损严重或者使用效果不佳时，应及时更换新的橡皮擦。 四、其他注意事项 1. 避免与尖锐物品接触：橡皮擦表面较软，容易受到尖锐物品的划伤，因此应避免与尖锐物品接触。 2. 不要长时间不使用：长时间不使用的橡皮擦容易干燥变硬，影响使用效果。因此，即使不经常使用，也应定期拿出来使用一下。 以上这些技巧可以帮助我们更好地保养橡皮擦，延长其使用寿命。接下来我们将这些技巧翻译成英文： Tips for Eraser Care: Secrets to Prolong Its Lifespan Eraser is one of the indispensable writing instruments in our study and work.

Avoid direct sunlight: The eraser should be stored in a cool and dry place, away from direct sunlight to prevent deformation or deterioration. 2. Keep away from dampness: A damp environment can easily cause the eraser to mold or deteriorate, so it should be stored in a dry place. Third, maintenance methods:

Replace with a new eraser: If the surface of the eraser is severely worn or its performance is poor, it is recommended to replace it with a new one promptly. Fourth, other precautions: 1. Avoid contact with sharp objects: The surface of the eraser is soft and prone to being scratched by sharp objects, so it should be kept away from them. 2. Don't leave unused for a long time: An eraser that is left unused for a long time may become dry and hard, affecting its performance. Therefore, even if not used frequently, it should be taken out and used periodically. By following these tips, you can better maintain your erasers and prolong their lifespan effectively.
