So you have stepped into the process of cleaning the projector’s lens. The first step you need to take is to make sure that the projector is completely cooled down.

During usage, the lens is warmed up easily. So if you have used the projector freshly, then switch it off and remove all the cables. Let the projector cool down completely for at least 30-60 minutes. Cleaning the projector’s lens without letting it cool down results in scratches and damage.

To clean the inside of the lens, you have to open the projector. Note that the opening of the projector will vary, based on the brand. Every brand has different ways of opening the projector. To check the way of opening your projector, see the user manual. In some projectors, a button is also present for the opening.

Step 3: Gently Clean the Projector’s Inside

After opening the projector, take the compressed air spray to remove all the dust. Carefully use the spray and keep it at least 4 inches away from the projector.

Now the second thing you need to do is to use a soft cleaning cloth to wipe the dirt and moisture. Dirt usually accumulates around the moisture; make sure to wipe it properly by using a cleaning cloth.

Step 4: Clean the Lens

The last but the most important step: cleaning the lens. Since you have cleaned the inside of the lens and projector, now learn how to clean it externally. First, remove the lens cap and clean the dust by using compressed air spray.

After cleaning the dust, take the lens cleaning solution and drop only 1-2 drops of it on the cleaning cloth of the lens. Now gently clean it. Clean it in a circular motion, starting from the center to the edges. Similarly, if you are using a cleaning brush, then use the same procedure to clean it.

Disclaimer: Remember that only 1-2 drops of lens cleaning solution are enough. The more you use, the harder it will be to clean it. And also, never put the cleaning solution on the lens. Always drop it on the cleaning brush or cloth.

Lastly, put the lens cap back on it.
