Once you have gained access to inside a projector, you will now have to use the compressed air to blow away the dust. Keep the nozzle a few inches away from the projector and target all the dust on the edges. You should opt for the cleaning of the total housing, especially the fan area that catches the maximum amount of dust.

Rather than going for a long press, you should press at regular intervals to target specific dust areas, and it will help you to effectively clean the interior area. The nozzle will help you to target various close areas which you can’t easily clean with a cloth.

This process is really important because it will help you create a smooth and clean surface before applying a solution based cleaning agent. More importantly, if you don’t clean the remaining dust and apply a solution agent, it will make conditions much worse than before.

Clear All the Dirt and Dust on Exterior

Now that you have a squeaky clean interior, it is time to remove any dust and dirt lying on the exterior of the projector. You can use the microfiber cloth or any other cloth to clear all the dust on the exterior.

For effectiveness, you take out the air vents (most attached with a latch) and clean them specifically to get a squeaky clean surface.

Clean the Lens

Before you start the cleaning process, it would be best to take out the lens cap. Now, add two to three drops of lens cleaner on the tissue or microfiber glass and gently apply it over the lens.

While cleaning, it is advisable to wipe the lens in a circular way because it offers maximum effectiveness during cleaning. After cleaning the lens, you quickly cover it with the lens because the lens cleaner dries up quickly, so there is no need to wait.

Now, your lens is immaculate, and you will have optimum image quality and clarity while you project something on the big screen. Many users have stated that after cleaning the lens, the brightness of the projector also gets restored.
