Do you have a PC at your home? Do you clean and dust it regularly? If not, you may have to be in a great trouble. If you clean your computer and the various computer components on a regular basis, it will be in a good condition for working for a long period. Again, it will not spread germs. Some conditions tell you how often you should clean your computer. It depends on some variables like pets at home and smoking. If you do not smoke and you do not have a pet in your home then you can clean your computer every five months. If you have pet/s and you do not smoke, you need to clean it every four months. If you smoke and do not have pet, you should clean your PC every three months. In addition, the worse, if you smoke and have pet/s, you need to clean your computer every two months.
An important point to notice: never clean your PC or PC Parts with any liquid spray. If you want, you can spray the liquid on a clean cloth, and then use it to rub down the components. The best suggestion is to use a vacuum cleaner to suck up the dirt and hair around the machine. However, never use it to clean the CPU, because it produces lots of static electricity that can damage the inner circuits. For your computer monitor, use liquid spray, but not apply it directly. Never use a paper to clean your monitor. It may leave scratch marks.
Take care of your PC. You can enhance the longevity of the machine by cleaning it regularly.
