Routine care and proper maintenance of microscope will ensure good performance over the years. In addition to this, a properly maintained and clean microscope will always be ready for use at any time. Professional cleaning and maintenance should be considered when routine techniques fail to produce optimal performance of the microscope.
 
Cleaning and maintenance supplies
 
Dust cover: When not in use, a microscope should be covered to protect it from dust, hair, and any other possible sources of dirt. It is important to note that a dust cover should never be placed over a microscope while the illuminator is still on.
 
Lens tissue: Lint-free lens tissues are delicate wipes that would not scratch the surface of the oculars or objective. Always ensure that you are using these types of tissues. Never substitute facial tissue or paper towel, as they are too abrasive.
 
Lens cleaner: Lens cleaning solution assists in removing fingerprints and smudges on lenses and objectives. Apply the lens cleaner to the lens tissue paper and clean/polish the surface.
 
Compressed air duster: Using compressed air to rid the microscope of dust particles is far superior to using your own breath and blowing onto the microscope. Compressed air is clean, and avoids possible contamination of saliva particles.
 
Maintenance tips
 
  1. Whenever the microscope is not in use, turn off the illuminator. This will greatly extend the life of the bulb, as well as keep the temperature down during extended periods of laboratory work.
  2. When cleaning the microscope, use distilled water or lens cleaner. Avoid using other chemicals or solvents, as they may be corrosive to the rubber or lens mounts.
  3. After using immersion oil, clean off any residue immediately. Avoid rotating the 40× objective through immersion oil. If this should occur, immediately clean the 40× objective with lens cleaner before the oil has a chance to dry.
  4. Do not be afraid to use many sheets of lens tissue when cleaning. Use a fresh piece (or a clean area of the same piece) when moving to a different part of the microscope. This avoids tracking dirt/oil/residue to other areas of the microscope.
  5. Store the microscope safely with the stage lowered and the smallest objective in position (4× or 10×). This placement allows for the greatest distance between the stage and the objective. If the microscope is bumped, the likelihood of an objective becoming damaged by the stage surface will be greatly minimized.
