How to clean projector lens? Here I have explained everything.
Generally, If you are seeing dust accumulated over your projector lens. You can use microfiber cloths or a camera lens cleaning brush. More you can do use q-tip and distilled water.
If your projector lens needs serious cleaning. Then you have to use the lens cleaning solution and microfibre cloth.
A more detailed explanation is ahead.
How to clean the projector lens from the outside?
Here, I am going to teach. The two ways to clean the lens are with the q-tip and purified water or distilled water and another with lens cleaning solution.
Before cleaning the projector lens with purified water. Or distilled water and cleaning solution. Take the soft lens cleaning brush. And clean the excess dust.
Or use the giottos Rocket Air Blaster. To remove the excess dust from the projector lens.
You can also follow these steps to clean the lens. If the first cure doesn’t work for you.
- Blow air or use a microfiber cloth. To remove the extra dust on the lens.
- With the purified water or distilled water.
- Take the q-tip and dip it into the distilled water. No tap water. (Make sure you are using the q-tip that does not fall fibre.)
- Then extract the excess water. Use a clean cloth. Rollover your q-tip on the clean cloth.
- Now in the circular motion move your hand over the projector lens. Gently do this all over the lens. Start from the centre. And end with the edges of the projector lens.
- If there is excess water left on the projector lens. No need to worry. Take another q-tip and move over the projector lens. It will absorb the excess water.
Moving to the second way.
- Blow air or use a microfiber cloth. To remove the extra dust on the lens.
- Take the lint-free microfiber cloth.
- Don’t use the excess lens cleaning solution. Take a little solution on the cloth.
- And rub over the projector lens. Gently all over the projector lens.
- If some extra solution is left over the projector lens. Then use another dry microfiber cloth. And rub over the projector lens. It will absorb the extra solution.
So, all these are the external efforts you can do to clean the projector screen. From the outside.
How to clean the inside of a projector lens?
If you are thinking I will tell you how you can disassemble the projector lens. And how to clean the projector lens from the inside. Then you are thinking wrong.
Because the projector lens is sealed with a lot of glass. And disassembling the lens glass will be stupidity. Because you are not fixing the problem. And you are hurting the projector lens.
The only way you can clean the lens is from the inside. You have to take the projector lens outside from its compartment.
Let’s see how you can take out the projector lens from its compartment/place step by step:-
- First, turn off the projector.
- And lose those screws. Which holds the projector’s upper part.
- Now you have opened the projector’s upper cover. So why do you not also clean the projector from the inside? Other than the projector lens. So before we start, disassemble the lens from its place and clean it.
- Take the vacuum air. And use it all around the inside of the projector. Where dust is collected.
- Now let’s back to our projector lens. Lose those screws which hold the projector lens. For that, I will suggest you look at your projector mechanical blueprint or manual. So you can know how properly you can take out the projector lens. From its place. And clean it.
- To clean you can use the giottos Rocket Air Blaster for the dust around the projector lens or use the microfiber cloth or soft brush. And to clean the rear part of the lens. I have already told you.
Do’s and Don’ts: How to clean a projector lens?
Let’s know. What things you should do while cleaning the projector? And should not.
- Don’t use an acidic cleaner, solvent, or alcohol as a cleaning liquid. And abrasive materials too. Because they will tear down the lens coating.
- Don’t use your mouth. Because when you eat something. Some food particles are left in your mouth. And then they start dissolving in your mouth. Which makes your mouth air acidic.
- No need to use dirty equipment to clean the lens. Because it will make your lens dirtier. Instead of cleaning the projector lens.
- Never use a cleaner that contains flammable gas.

- When applying the projector lens cleaning on the lens. Using the q-tip and microfiber cloth. I will suggest you do it in a circular motion.
- If you are using compressed air to clean the lens dust. Then I will suggest you blow compressed air seven inches away from the projector lens. Because it can hurt your projector lens.
- Contact your projector manufacturer. If there is any condition to not clean your projector lens. That affects your warranty.
- If it’s not necessary to clean the lens, don’t clean the lens.
When should you clean your projector lens?
You don’t need to always clean the lens. Because it can hurt the projector lens coating. And if that lens coating loses over the projector lens. Then it can be permanent.
Without any cure. And it will not be solved with a normal job. If your projector lens or coating hurts.
So, if on the lens it’s only the dust particle. To clean this doesn’t use the lens cleaning solution. Use the soft brush, microfiber cloth, or giottos Rocket Air Blaster.
If something is sticky, oily, and fingerprint smudge. Over the projector lens. Then use the lens cleaning solution and microfiber cloth. Or qtip with the distilled water.
And if there is something like scratch. Then you have to use the Lens repairing tool-Dremel, Polishing Set.
And Polishing compound. Or Microfiber cloth, q-tip/cotton swabs, and Meguiar’s Compound.
