If there is only dust on the microscope optics, it is best to remove it with compressed air. This method is particularly gentle to prevent damage to optical components. In general, a small lens blows balloons enough to produce the desired airflow.

When removing stubborn dirt, never use materials that generate friction, such as paper or microfiber cloth, as they damage the lens surface and cause scratches. In addition to this, do not remove the stubborn dirt and dry it. Another key point to remember is that only pure solvents, distilled water and clean tools are available. Always use cleaning fluids and qualified medical swabs or pads to ensure they are clean enough and do not contain any impurities. Avoid using ammonium-containing solvents.
