Projectors have become one of the essential machines. They are being used a lot in businesses, schools, government agencies, homes, and most of the meetings are done through the use of projectors.
Therefore, projectors have become an all-one-in solution for both office work and home entertainment. But this solution has got some problem. One of the problems is that after a few days of use, the lens of the projector accumulates dust and the image becomes blurred or imprinted. It creates murky clouds across the image with reduced brightness and sharpness.
Do you know why it happens? It happens because of dust and fungus. Due to the humidity of the air, dust and fungus get stuck inside the projector lens, which is very difficult to remove without proper cleaning. That’s why it is quite crucial to clean your machines, like paper shredder regularly.
If you are one of them who is looking for a solution to this kind of problem, then this article is written for you. In this article, I will explain how to clean projector lens from inside.
So without further talk, let’s get started.
Follow these steps to clean your projector’s lens from inside –
1. Get Your Materials
To start cleaning your projector lens, you will require these materials –
- Compressed air
- Moisture cloth
- Microfiber cloth
- Tissue paper
- Lens cleaning solution
Make sure you have all these things ready to start the process. If you don’t have any of them then you can buy them from a local store or order them online at Amazon.
2. Turn the projector OFF
Before you start to clean the projector lens, first of all, turn it off and unplug the cable. If you have been using the projector continuously, give it some to cool before you start.
When the projector runs continuously, then it can get really hot. And when the projector is hot then it will be better if you cool the projector down before opening it. Because, when the lens is cool, it is safe to clean and unlikely to break easily.
3. Open the Projector
When you turn off the projector and the projector’s lens is all cool, then it is the perfect time to open the projector.
You should know that every projector model is different. Therefore, it will be better if you look at the given manual. The manual will help you to understand the way you can open the projector correctly.
Usually, there is a latch or button on the projector housing in most of the projectors. If your projector has that button then press it gently to open the projector.
4. Clean inside with compressed air
Now you have to clean the projector’s inside with compressed air. Take the can of compressed air and spray inside with short bursts. Hold the can roughly 3 or 4 inches from the projector so that you can clean the biggest traces of dust. Target the dust you see on the projector first and then move the nozzle around it to clean it off.
Keep doing this for a while, paying attention to the fan to clean accumulated dust. Besides, you should also clean the projector’s housing and remove the dust inside the projector.
It is quite hard to remove all the dust in the projector. Therefore, try to remove as much dust as possible. Also, make sure you are not sending the dust back into the projector. You can use a microfiber cloth to wipe out the visible dust.
5. Remove traces of dust
After you have successfully cleaned the inside, now remove all the traces of dust from the case using a moisture cloth. Especially focus on the fan vent and surrounding area.
This step is very important because the cleaner the projector case and lens are, the more sharpness you will get on the screen.
After you have cleaned the projector’s inside, clean the projector’s housing. Now you have to clean the lens properly. Because, when the lens is not properly cleaned, the images tend to have clouds, affecting the sharpness and brightness.
6. Clean the lens
So, as you cleaned the inside of the projector and other parts properly, now it is the final lens touch. This is the main part of the projector lens cleaning process.
First of all, remove the lens cap and put a drop or two of the lens cleaning solution on a tissue paper or microfiber cloth, and slowly wipe the lens in a circular motion. The circular motion is important because it helps to clean the lens without leaving it dirtier.
Once you are done, replace the lens cap, and have it right in place.
