The Lunar Laser Ranging Retro-reflectors (LRR) allow for the precise measurement of the travel time of laser pulses from the Earth to the lunar surface and back. Dust accumulation on the LRRs scatters the reflected light used for laser interferometry measurements leading to a reduction in the return signal amplitude by a factor of $\simeq$10. We report on a series of experiments utilizing a method of an iterative application and removal of an acrylic adhesive kapton tape to remove lunar dust simulant from a glass substrate. The effectiveness of adhesive tape was determined by measuring the transmission of an expanded laser beam through a glass substrate with a dusted surface. Calibration data was obtained before the glass was exposed to any dust, and light transmission was measured after each iteration of adhesive removal using a power meter. The procedure was repeated using heavy gloves while keeping the glass substrate at 120$°$C to simulate the temperature conditions of a lunar day on the surface. A third test was conducted at room temperature in high-vacuum to ensure functionality in the lunar environment. These experiments show that glass substrates can be restored to 98 $\pm$ 2 % of their original transmission using the adhesive tape method. Therefore the light that travels into and out of the quartz surface of the LLRs can be restored up to 96 $\pm$ 4 % of their initial transmission.

月球激光测距后向反射器 (LRR) 可以精确测量激光脉冲从地球到月球表面再返回的传播时间。LRR 上的灰尘堆积会散射用于激光干涉测量的反射光，导致返回信号幅度降低$\simeq$10. 我们报告了一系列实验，这些实验利用迭代应用和去除丙烯酸粘合剂 kapton 胶带的方法从玻璃基板上去除月球尘埃模拟物。胶带的有效性是通过测量扩展的激光束穿过带有灰尘表面的玻璃基板的透射率来确定的。在玻璃暴露于任何灰尘之前获得校准数据，并且在每次去除粘合剂重复之后使用功率计测量透光率。使用厚手套重复该过程，同时将玻璃基板保持在 120$°$C 模拟月球表面的温度条件。第三次测试是在室温和高真空下进行的，以确保在月球环境中的功能。这些实验表明玻璃基板可以恢复到 98$\pm$2 % 的原始传输使用胶带方法。因此，进出 LLR 石英表面的光最多可以恢复 96$\pm$ 4% 的初始传输。
