1. Make sure the power is turned off.
Before cleaning the projector, it must be confirmed that the power supply has been turned off and the light bulb has been completely cooled to avoid safety accidents.
Use the right tools
The cleaning equipment of the projector should be specially designed, and improper tools will have a bad influence on the projector. You can buy special projector cleaning sticks, professional electric vacuum cleaners and plasticine wipers in the market.
3. Remove the dust filter of the projector.
Many models of projectors have built-in dust filters, and the dust in the projectors will be filtered through the filters. If the filter is full, the heat dissipation of the projector will be affected and the dust will also affect the projection effect. So it is very important to clean the dust filter in time.
Step 4 use a professional vacuum cleaner
Traditional cleaning methods use brushes and other tools to clean dust, but this method can not completely remove very tiny dust particles in the projector. Using a professional vacuum cleaner can avoid hardware wear, and more importantly, avoid the influence of extremely fine dust particles that cannot be cleaned on the projection effect.
5. Don't use water or chemical cleaners.
Don't clean components such as projector and dust filter with water or chemical cleaner, because it will damage the equipment. Use clean rags, such as professional pneumatic rags or antistatic rags.
In addition to these methods, the annual inspection of the projector is also an important one. With equipment maintenance and regular start-up operation, various problems in daily use can be effectively avoided. A well-maintained projector can ensure a lasting and realistic high-quality projection effect. The maintenance cycle depends on the amount of dust brought by the city and the environment, and it is usually cleaned once every one or two months.
