Like any electronics or technology, projectors require careful handling and proper care. The accumulation of dust and other contaminants, fingerprints, and lens buildup can significantly degrade the performance of the equipment. And to prolong the life of the lamp and the entire projector, it is vital to clean promptly. It will help prevent overheating, noise, and deterioration of image quality.
As a result, your projector will work much better and last longer. Experts recommend performing such work at least once a year. Suppose the room is very dusty, once every six months. It is essential to unplug the equipment and give it time to cool down thoroughly after work.
The following instructions will help you clean your projector safely and effectively.
Cleaning the air filter and housing
According to the advice of experts, you should clean the air filter every 3-4 months, removing accumulations of dust from it. The projector part gets dirty the most because the filter collects all the dust and prevents it from getting inside the projector. Cleaning or replacing this projector part is the first thing you should do to avoid overheating the equipment.
Please note only dry cleaning is applied. It is not allowed to wash the air filter with water and wipe it with a wet rag or sponge. It is best to use a vacuum cleaner or a soft brush for cleaning. Otherwise, it will simply malfunction, and you will need a complete replacement.
The cleaning steps are pretty simple:
- Remove the ventilation grille and take out the filter from the special compartment.
- We put the front side down and several times gently tap it with the palm of our hand, shaking out the dust. It would be best if you repeated the same for the other side. Control the force of the blows so as not to damage the somewhat fragile construction.
- Carefully remove the remaining dust with a brush or vacuum cleaner.
- Put the filter back in the compartment and replace the ventilation grille
In some cases, it may be necessary to replace the filter. For example, if there is no way to clean the contaminants or filter completely is damaged. Do not continue to use a flawed air filter.
Wipe the housing with a soft cloth moistened in water. It is advisable not to use any detergents in this process. You should wring out the material as much as possible, leaving it slightly damp. After direct cleaning, it is essential to wipe the case completely dry. Only then can the projector be plugged back in.
It is crucial not to use alcohol-based solutions, various solvents, and wax polishes for cleaning, and they can severely damage the case and render the unit unusable.
Cleaning the projector lens
Cleaning your optics is a complicated process that requires attention. You must wear gloves to prevent fingerprints from appearing on the lens. Otherwise, there is a chance of losing focus, and the image will lose its clarity.
Be sure to use lens cleaners explicitly designed for lenses. You can buy them in specialized stores, and these can be entire cleaning kits or individual liquids. We recommend purchasing a complete set, as it will contain everything you need to clean the projector lens quickly and safely.
The process has into several steps:
- First of all, we blow off coarse dust and debris particles. To do this, use a blower that produces a jet of air when you press it. Direct it so that it sweeps the dust away.
- Use a soft brush or a special pencil to remove the remaining dust from the lens. Make sure that dirt does not get inside the lens.
- It requires a special liquid and a soft cloth or a special cloth. Clean the lens in a circular motion, wiping off dirt and grease stains. Then take a dry cloth and carefully wipe the lens dry. Now proceed to wet cleaning.
- Wipe the focus sensors with the wipes.
Please note that cleaning the projector’s internal parts is rather laborious and complicated. Do not take it on if you are not confident in your abilities, in this case, and it would be best if you entrusted the work to professionals.
