Microscopes are one of the essential lab tools for scientists and students. However, like any other equipment, they can get dirty over time. By following the proper cleaning process, you can keep your microscope functioning at its best. We covered cleaning the mechanical components, lenses, and mold area.
Several years ago, I was reading the statistics for microscope cleaning products. According to the manufacturer, one, in particular, stood out: if you clean only twice a year, you’re probably missing 90% of your sample. You’re missing more than 80% if you clean twice a month. It’s hard to imagine how important this is since most of us don’t even realize that we do not see our samples.
Always read all instructions carefully before cleaning your microscope, as any mistake could ruin your equipment. As always, exercise caution when cleaning delicate equipment and wash your hands thoroughly before and after each step. Stay tuned for more updates on microscope cleaning!

I always use Household cleaners to clean the eyepieces, lenses, and other optical components. These cleaners are safe on most surfaces and effectively remove dirt, dust, and fingerprints.
If you want to use a microscope cleaning kit, you will need to mix the cleaner with water and scrub the parts of the microscope that need cleaning.
The steamer gently cleans the microscope using steam to loosen any dirt or debris. Just be sure to avoid any contact with the glass surface of the microscope, or you will damage it.
Cleaning the microscope’s mechanical part is daunting if you are not an expert. But you can do it quickly and easily with preparation and organization. The most common methods include household cleaners, a microscope cleaning kit, or a steamer.
Process to Follow
To keep it clean, we know that you should wipe the exterior with a moist paper towel, avoid touching the lenses if possible, and dry everything off before using it again. That’s all well and good, but how should you clean it? It can be tough to figure out what steps to take when you don’t have instructions. Here are a few tips:
1. Unplug the microscope and wipe the exterior with a wet paper towel.
2. Carefully remove the impurities from the inside of the microscope using a paper towel.
3. Dry everything off before storing or using the microscope again.
4. We recommend using distilled water to clean microscopes instead of tap or city water since it is safer and causes less fogging.
5. Remember that humidity will prevent condensation in your microscope, so if you live in a humid area, ensure it’s as low as possible!
Using dish soap
We all know that microscopes are expensive, so you don’t want to risk damaging them and wrongly caring for them. To properly clean a microscope, follow these steps:
1. Fill a sink with room-temperature water and add soap until it makes a pile of foam
2. Swish the solution around on the scope to make sure it’s sudsy
3. Wipe away any dust with a cloth and rinse off the area with room-temperature water
4. If your microscope is dirty or oily, use 10% alcohol to clean it; but be careful not to use this if it’s dry
5. Repeat the alcohol process twice or three times, then finish with distilled water
6. After cleaning the mechanical parts, clean around the optics by wiping them with the solution and cloth.
7. When done, dry it off and store it in a dust-free place.
Using white vinegar
Sometimes you need to get gross. When trying out different cleaning methods, sometimes it’s still hard to determine when a solution is doing something. Cleaning the microscope using white vinegar is a simple and effective way to keep it in excellent condition. It would be best to have a few supplies, including white vinegar, a microscope lens cleaning cloth, and a brush.
First, pour white vinegar into a small bowl.
Then, wet the cleaning cloth and wring it slightly damp.
Place the cloth on the microscope lens and rub it around in a circular motion.
Make sure to get into all the corners and crevices.
Finally, use the brush to clean any residue that may have accumulated.
After cleaning the lens, dry it off with the cloth and store the microscope in a clean and dust-free environment.
To be on the safe side, wipe the microscope with a clean cloth or several to ensure that any excess liquid is removed. If there was no way to completely clean the eyepiece tube with a damp cloth, use this cloth to do so. You can also use it to remove any liquid from the eyepiece tube if necessary. Always use new material to ensure you’re dry and ready to go.
How do you clean the lenses of your microscope?
Cleaning your microscope lenses is scary, but it can be a breeze with patience and practice. There are a few different ways to clean your lenses, and each has its benefits and drawbacks.
The most common way to clean lenses is to use water and alcohol. This solution effectively removes dust and other particles, but it can be difficult to remove dried residues.
Another method is to use a KOH solution. This solution is less abrasive and can clean lenses that are difficult to dry. It is also effective in removing oil and grease but can damage the lens if misused. The final method uses a mechanical cleaner specifically designed for microscope lenses. This cleaner is safe to use and has no adverse effects on the lens.
Ultimately, the best way to clean your microscope lenses is to experiment and find what works best.
Dusty lenses are a problem you can’t cure with a quick wipe.
The best way to cleanse dusty lenses is by using a vacuum or dusting brush. It will take patience, but you must do it carefully so your lens doesn’t get any worse.
You must use an optical dusting brush to clean these microscopic lenses properly. You can purchase one at most stores that sell lab equipment and microscopes.
Before inserting it, you just prepped a lens and noticed some dust on the surface. How do you clean them off? There are a couple of solutions to avoid damaging your lenses.
You can use an oil-free compressed gas or gently vacuum around the frame with a dust brush. It’s essential to avoid using a keyboard cleaner for this, as those products could damage your lenses. For example, dry-nitrogen-propelled compressed air is an excellent solution if it’s not too cold outside.
The first time I used a microscope, I got it dirty. That was my fault for not realizing the lenses needed to be cleaned. (I went into my lab’s storage and found a cotton swab, water, and soap to clean it.) When you’re out of solutions, isopropyl alcohol works wonders — and you can find it at any store that sells microscopes and lab equipment. Another tip:
Don’t use a cloth to clean the lenses when you’re out of your favorite solution. Clothes are too large and will spill cleaning liquid on your instrument if they are not lint-free.
You might not think about it, but your lens is filthy. Agree? The center of the lens is where all the dirt has gathered, so you need to get it as clean as possible.
A cotton swab and liquid dish soap are all you need to clean your smudged lenses. Apply the soap to the cotton swab and gently rub it on the center of your lenses in a circular motion.
That is where the dirt has gathered, so it’s important to scrub it. After, clean outward across the lens, moving about an inch at a time away from the center. Continue until your lenses are both free of dirt! Be sure to use a light touch not to scratch the lens.
What are three things you should do when cleaning up a microscope?
When cleaning up a microscope, make sure to do the following:
Hand hygiene is one of the essential steps in preventing infection. Before touching your microscope, wash your hands thoroughly with soap and water. This includes everything from your hands and wrists to your elbows and knees. It is also essential to avoid contact with your eyes, as this can lead to eye irritation or even conjunctivitis. Finally, avoid touching your face, which can lead to skin infections.
1. Always wash your hands before putting on latex gloves.
2. Be sure to wipe down the surface area after each person uses it for multi-person-use microscopes. This will keep you from worrying about someone else’s bacteria left behind on the surface after it is touched.
3. It’s recommended not to eat or drink before, during, or directly after using your microscope, as it can be messy, and food particles may get on the microscope.
4. If you store your microscope under questionable conditions (i.e., in a room that might reach 80° F or higher), dust it off after usage and wipe the inside with rubbing alcohol, wiping off any other residues on the surface before using again.
Covering your microscope whenever you put it away is a simple but important step that can help keep it in good condition and protect it from dust and other particles. This will help protect the microscope from damage and prevent the light from being scattered, leading to inaccurate images.
Additionally, it is vital to keep the microscope clean to function at its best. Cleaning the optics and the eyepieces with a suitable solution can help remove dirt, dust, and other debris that can cause degradation.
Remember to regularly check the covers and hinges to ensure that they are secure and free from signs of wear or tear. If you notice any problems, don’t hesitate to contact your microscope supplier for assistance. Deteriorated covers can lead to distortions in your image and other issues.
Once you are done using the microscope, remember to protect it from scratches and dirt with a dust cover or put it away properly before storing it for future use. This will protect your microscope and those who may one day come across it after it’s been misplaced!
Failing to put a cover on your microscope when you pack it away is never good. It can result in dust particles and impurities getting into the optics and onto the slides, confusing your technician or student. In most cases, the best cover for your microscope is the one that came with it from the manufacturer.
Covering your microscope with two bags will do the trick if you don’t have this dust cover. Put one sack over the top and another lower, securing both with a string.
The most important thing you can do to maintain your microscope is to prevent fungus. This can be done by storing it in a dry place, like a closet, where the relative humidity will be low.
A humid environment like a room can be one of the worst places to store a microscope because it gives the fungi more room to grow. You should invest in an air conditioner or an infrared lamp to keep your microscope clean and fungus-free even when temperatures soar. Removing fungus from a microscope is not easy, so it’s best to avoid it!
It’s essential to store your microscope away from corrosive vapors. These vapors can be acidic or alkaline and may cause significant damage to your equipment. Keep your equipment in a different room when performing experiments with these kinds of smoke.
It’s best to store your sensitive equipment in another room while conducting acid or alkaline vapors experiments. These fumes can corrode your equipment, so storing it in a different space is best to keep it safe.
