Never touch the microscope lens with your fingertips since fingerprints can affect the microscope's visibility. When fingerprints are dried onto the lens, it is very difficult to remove them and this should be done with distilled water.

If it is loose debris, the easiest way to remove it is by gently applying some compressed air so it simply blows away.


If the dirt doesn't come off with air, then add a few drops of ether on the cotton or lens cleaning paper and gently clean the lens.


Rub the lens cleaning paper that has been soaked in ether over the microscope lens making circular movements as you go.

For this you can use "clean lens" paper with a drop of xylene.


To protect the lens, it is customary to place the value of a smaller increase on the gauge and to go down in focus till the capacitor is in its lowest position.


To avoid skipping over any of the focus points. Store the lens in a dry place to prevent moisture and fungal growth. Certain acids and other chemicals that produce strong fumes. These should be kept away from the microscope.


When drying the microscope lens after cleaning, do not use dryers or any appliances. Let it dry naturally.
