How to Clean a Projector Inside Lens? Step By Step Guideline

How to Clean a Projector Inside Lens

Dust is literally everywhere. Even if you set the projector higher up on the ceiling, a layer of dust will accumulate on the upper portion of the casing over time. But that is not the only place where you will find dust. The dust can even make its way to the inside lens of the projector.

If you plan to leave the lens like that, the images can get blurry. In fact, the dust embedded in the lens can even lower the brightness and sharpness of the pictures. That is why knowing how to clean a projector inside lens is pretty essential.

But the sad part is that most of the guides will make this process seem harder than it already is. Trust us; as professionals who handle projectors regularly, it is not that hard at all. Do not trust us? Read through the entire article to find out!

Step by Step Process to Cleaning a Projector Inside Lens

We believe in keeping things simple. So, instead of working with intricate materials and tools, we managed to find the simplest way to clean the inside lens of the projector. So, without further ado, let us get into describing the steps:

Step 1: Get the Required Tools and Materials

Before you start the cleaning process, you would need to get a couple of things. Wondering what things are we actually referring to? Here is the list:

  • Lens cleaning solution
  • Compressed air
  • Tissue papers
  • Microfiber cloth
  • Lens cleaning papers

Keep all of these nearby so that you do not face any interruptions while carrying out the cleaning process. Also, we would highly recommend not to use any chemicals instead of the cleaning solution. It can cause scratches on the surface, which would call for a lens replacement.

Step 2: Open the Projector

Once you got all of the required materials, turn the projector off and take the power cord off. If the projector was on before you started the cleaning procedure, you need to wait for a while to allow the projector to cool down a bit. Thirty minutes would be good enough for this case.

If you initiate the cleaning process when the lens is hot, the lens cleaning solution might cause damage to the lens. That is something that you would not want to occur. So, wait for a while and then remove the lens.

How to open the internal lens of the projector? Well, you would need to press the button or unlatch the latch. If you are confused, you would need to refer to the manual that came with the projector.

Step 3: Clean the Inside with Compressed Air

Take a can of compressed air and attach the small pipe with it. By holding the can about three to four inches away from the projector, move the nozzle around on the places where you can see the dirt. Use compress air around the fan and throughout the entire housing to remove all the dust.

To ensure that the extracted dust is not blown back into the projector, you need to wipe away any visible dust or dirt with a microfiber cloth. Ensure that there is no visible dust present around and on top of the lens before moving to the next step.

Step 4: Clean the Exterior

You would need to take a clean microfiber cloth and moisten it with a bit of lens cleaning solution. Remove any traces of dust and dirt present on the housing using that moistened cloth.

Again, ensure that you are carrying out this step once you have cleared out all of the visible dust from the inside, or else the dust can stick to the surface pretty quickly. Spend a reasonable amount of time cleaning the fan vent and its surrounding area.

Step 5: Work with the Lens

At this point, most of the exterior and interior of the projector should be free of dust. So, you can initiate the lens cleaning process. Use the compressed air can again to eliminate the visible dust present on the lens’s surface. Take a microfiber cloth or tissue paper and wipe the remaining traces of the dust.

Next, dampen up a clean lens cleaning cloth and gently wipe the upper surface of the lens. First, spread the solution thoroughly. Ensure that you are utilizing a circular motion. Other cleaning methods might not be capable of taking the embedded dust away from the surface.

As the lens cleaner usually dries quickly, you would not have to dry the solution with compressed air. However, if you notice that the cleaner stays on the surface for an extended amount of time without drying, you might need to use a clean microfiber cloth to dry up the solution.

If you still see traces of dirt on the surface of the lens, dampen up a new lens cleaning cloth and go through the surface again. Also, while you are working with the lens, ensure that you are not putting too much pressure on the surface. That can cause damage to the lens.

Step 6: Put Everything Back Together

Once the lens and the inside of the projector are clean, you would need to place the cap back on. Reassemble the housing if you have disassembled it and take a test run. The blurriness and murky cloud from the projected images should now disappear.

How Often Should You Clean the Inside Lens of the Projector?

A well-maintained projector is a projector that will last for an extended amount of time without showing any issues. However, it would be best if you did not clean the lens that often. That will increase the chances of scratches and scuffs ending up on the surface.

So, how often should you carry out the cleaning process? Every three to four months for the fan housing. However, for the lens, clean it every six months.

How to Prevent Dust and Dirt from Ending up inside the lens?

You can prevent the dust and dirt from settling on the surface of the lens to some degree. First of all, keep the lens covered all the time that the projector is not on. If you have placed the projector at a higher place, keep something nearby that will help you reach it.

To keep the housing from getting too dirty, we would ensure covering it up with a clean cloth when it is not in use. However, don’t keep the cloth on when the projector is running. It will hinder the airflow and make the inside go hot. And projectors overheating is worse than having dirt on the inside.

Final Words

As you can see, learning how to clean a projector inside lens is not as complicated as many think. In fact, if you correctly follow the steps that we have mentioned, the entire process will seem like a piece of cake. However, as discussed above, do not clean the lens that often, or else you will scuff up the lens.
