How to clean Microscopes Immersion Oil?
If you are using a 100X objective with immersion oil, just simply "swipe" the excess oil off the lens with a kimwipe after use. Occasionally dust may build up on the lightly oiled surface so if you wish to completely remove the oil then you must use an oil soluble solvent. For the Type A or B immersion oil, you can use Naptha, Xylene, or turpentine (use very small amounts on the kimwipe). Do not use water, alcohol or acetone as the oil is insoluble to these solvents. Consult the MSDS info that is supplied with your immersion oil to see what solvents are recommended. To remove other oily substances, we recommend using the detergent called Wisk and prepare a solution of 1 part Wisk to 100 parts water.
