Cleaning your computer
General cleaning tips:
Below are tips that you should follow when cleaning any components of your computer or peripherals, as well as tips to help keep your computer clean.
- Never spray or spray liquid onto any computer component. If spray is required, spray liquid onto a cloth.
- You can use a vacuum cleaner to suck in dirt, dust or hair around the computer. However, do not use a vacuum cleaner inside your computer, as it generates static electricity that damages your computer. If you need to use a vacuum cleaner inside your computer, use a battery-powered portable vacuum cleaner or try compressed air.
- When cleaning a component or computer, turn it off before cleaning.
- Use caution when using cleaning solvents; some people have allergic reactions to chemicals in cleaning solvents, and some solvents can even damage the case. Always use water or a highly diluted solvent.
- While cleaning be careful not to accidentally adjust any knobs or controls. While cleaning the back of the computer, if something is connected, do not disconnect the connectors.
- When cleaning fans, especially smaller fans, hold the fan or place something between the fan blades to prevent it from rotating. Spraying compressed air into the fan or vacuum cleaning the fan may result in damage or reverse voltage.
- Never eat or drink at the computer.
- Limit smoking around the computer.
Cleaning tools:
Although computer cleaners are available, you can also use household items to clean your computer and its peripherals. The following is a list of items that you may need or that you want to use when cleaning your computer.
Cloth:
cotton cloth is the best tool for wiping computer components. Paper towels can be used with most equipment, but we always recommend using cloth when possible. However, use a cloth only to clean components such as the case, drive, mouse, and keyboard. Do not use a cloth to clean any circuitry such as RAM or the motherboard.
Water or alcohol:
When wetting the fabric, it is best to use water or alcohol. Other solvents may be harmful to the plastics used with your computer.
A portable vacuum cleaner:
Sucking dust, dirt, hair, cigarette particles and other particles from a computer may be one of the best methods for cleaning a computer. However, do not use a vacuum cleaner that plugs into the wall, as it creates a lot of static electricity that damages your computer.
Cotton swabs:
Cotton swabs moistened with rubbed alcohol or water are excellent tools for wiping hard-to-reach spots on the keyboard, mouse, and other places.
Foam swabs. If possible, it is best to use lint-free swabs, such as foam swabs.
Body cleaning:
What for?:
Cleaning your case retains the look of your computer in a new style. During cleaning, if you see ventilation openings, they can be cleaned or cleaned to ensure a constant flow of air into the computer and cooling of all components.
Procedure:
The plastic case in which the PC components are located can be wiped with a slightly damp, lint-free cloth. For stubborn stains, add some homemade detergent to the fabric. Do not use solvent to clean plastics.
Make sure that all ventilation holes and air holes are free of hair and lint by wiping the fabric through the holes and ventilation holes. It is also useful to create a vacuum around each hole, ventilation holes and slots on the computer. It is safe to use a standard vacuum cleaner when cleaning the computer’s external vents.
Cleaning CD-ROMs, DVDs, and other discs:
What for?:
A dirty CD-ROM drive or other drives may cause read errors while reading discs. These read errors can cause software installation problems or problems while the program is running.
Procedure:
To clean the CD-ROM drive, we recommend that you purchase a CD-ROM cleaner from your local dealer. Using a CD-ROM cleaner should sufficiently clean the CD-ROM laser of dust, dirt and hair.
You can also use a cloth dampened with water to clean the tray that is removed from the drive. However, make sure that after the tray is cleaned, it will dry completely before putting the tray back in the drive.
Cleaning CDs, DVDs, and other discs:
What for?
Dirty CDs may cause read errors or may not work at all.
Procedure:
Use a cleaning kit or a damp, clean cotton cloth to clean CDs, DVDs, and other discs. When cleaning the disc, wipe against the tracks, starting from the middle of the disc and wiping toward the outside. Never wipe with tracks; this may result in more scratches on the disc.
Hard Disk Cleanup:
What for & Procedure?
Computer hard drives cannot be physically cleaned. However, they can be cleaned using software utilities that will help it work quickly and efficiently. Using these utilities prevents the hard drive from slowing down.
Headphone cleaning:
What for?:
Headphones and earphones can be used by many different people, and they may need to be cleaned often to prevent the spread of germs and lice.
Procedure:
If the headphones are plastic or vinyl, moisten the cloth with warm water and wipe the head and headphones.
Headphones with pillows also have the ability to replace pillows. Replacing these pillows can also help keep your headphones clean.
Finally, with regards to headphones that distribute lice. If different students use the same headphones, ask them to use their own headphones, put on bags or use headphones that you can wipe with warm water after each use.
Keyboard cleaning:
These steps are designed to clean the keyboard on the desktop.
Dust, dirt and bacteria:
A computer keyboard is usually the most microbial-infected item in your home or office. The keyboard may even contain more bacteria than your toilet. Cleaning it helps to remove any dangerous bacteria and ensures the normal operation of the keyboard.
Procedure:
Before cleaning the keyboard, first turn off the computer or, if you are using a USB keyboard, disconnect it from the computer. Disabling the keyboard can cause other problems with the computer, as you can press keys that cause the computer to perform a task that you do not want it to perform.
Many people clean the keyboard by turning it over and turning it over. And best effective method is to use compressed air. Compressed air is compressed air contained in a can with a very long nozzle. To clean the keyboard with compressed air, aim between the keys and blow away all the dust and debris that has collected there. The vacuum cleaner can also be used, but make sure that the keyboard does not have loose “push-out” keys that can be sucked in by the vacuum cleaner.
After removing dust, dirt and hair. Spray the disinfectant onto a cloth or use a disinfectant and wipe each of the keys on the keyboard. As indicated in our general cleaning tips, never spray liquid on the keyboard.
Substance spilled on the keyboard:
If something spills on the keyboard (for example, pop, cola, Pepsi, cola, beer, wine, coffee and milk), improper actions can destroy the keyboard.
Procedure: The following are recommendations to help prevent the keyboard from degrading after something spills onto the keys.
If something spills onto the keyboard, turn off the computer immediately, or at least disconnect the keyboard from the computer. After that, turn the keyboard over to prevent the substance from entering the circuit. When keyboard is upside down, shake the keyboard over a surface that can be cleaned later. Use a cloth to start cleaning the keys. After cleaning the keyboard, leave it turned upside down for at least two days to dry. After drying, continue to clean the keyboard with the remaining material.
If after cleaning the keyboard keys are stuck, remove them and clean them under the keys and the bottom of the key.
Finally, if the keyboard still works, but remains dirty or sticky, before you throw it away as a last resort, try washing the keyboard in the dishwasher.
LCD / LED cleaning:
What for?:
Dirt, dust, and fingerprints can cause difficulty reading your computer screen.
Procedure:
Unlike a computer monitor with a cathode ray tube, the LCD monitor or LED monitor are not glass and require special cleaning procedures.
When cleaning the LCD or LED screen, it is important to remember that liquids should not be sprayed directly onto the screen. Press gently during cleaning and do not use a paper towel, as it may scratch the screen.
Use a soft microfiber cloth, soft cotton cloth, or a Swiffer rag to clean the LCD or LED screen. If a dry cloth does not clean the screen completely, you can apply rubbing alcohol to the cloth and wipe the screen with a damp cloth. Rubbing alcohol is used to clean LCD monitors and LED monitors before leaving the factory.
Motherboard cleaning:
What for?:
Dust and especially particles of cigarette smoke can accumulate and corrode electrical circuits, causing various problems, such as a computer freeze.
Procedure:
When cleaning the motherboard from dust, dirt or hair, it is recommended to use compressed air. When using compressed air, keep it upright to prevent any chemicals from escaping from the container, which could damage the motherboard or other components. In addition, when using compressed air, make sure that you always remove dust or dirt from the motherboard or the case.
Another good alternative to compressed air is a battery-powered handheld vacuum cleaner. Portable vacuum cleaners can effectively remove dust, dirt and hair from the motherboard and prevent it from getting into the case.
Warning: Never use an electric vacuum cleaner, as this can cause static electricity, which can damage the computer. When using a battery-powered vacuum cleaner, keep it a few inches from the components to prevent damage and suction of anything in a vacuum (such as jumpers).
Computer mouse cleaning:
Optical or laser mouse
What for?:
A dirty optical or laser mouse can make it difficult to move or move the mouse cursor.
Procedure: Use a can of compressed air that is designed for use with electronic equipment by spraying around the optical sensor on the bottom of the mouse. Blowing air from the bottom of the mouse removes dirt, dust, hair, and other obstructions that may block the optical sensor.
Do not use cleaning products or wipe the cloth directly on the optical sensor, as this may scratch or damage the optical sensor.
Optical-mechanical mouse (ball mouse):
What for?
A dirty optical-mechanical mouse (a mouse with a ball) can interfere with mouse movement and also cause strange mouse movements.
Procedure:
To clean the rollers of an optomechanical mouse, first remove the bottom cover of the mouse. To do this, inspect the bottom of the mouse to see in which direction the lid rotates. As you can see in the figure below, the mouse cover should move counterclockwise. Place two fingers on the mouse cover, press down and rotate in the direction of the arrows.
Once the cover has turned about an inch, rotate the mouse to its normal position, covering the bottom of the mouse with one hand. Then the bottom should fall, including the ball of the mouse. If the cover does not fall, try shaking the mouse slightly.
After removing the bottom cover and the ball, three rollers should be visible inside the mouse. Use a cotton swab, finger, or nail to remove any material from the rollers. Usually in the center of the roller there is a small strip of hair and dirt. Remove as much of this substance as possible.
Once you have removed as much dirt and hair as possible, put the ball back in the mouse and put on the cap.
If the mouse has the same problems, repeat the process described above. If after several attempts the mouse has the same problems, your mouse has other hardware problems and should be replaced.
The note: Cleaning the mouse pad with a damp cloth can also help improve mouse movement.
All types of mice
What for?:
Keep your mouse clean and free of germs.
Procedure:
Use a cloth dipped in alcohol or warm water and wipe the surface of the mouse and each of the buttons.
Printer cleaning:
What for?:
Cleaning the outside of the printer can help maintain the appearance of the printer, and if it is used by different people, keep microbes out of the printer.
Procedure:
First of all, be sure to turn off the printer before cleaning. Dampen the cloth with water or alcohol and wipe the case and each of the buttons or knobs on the printer. As mentioned earlier, never spray liquid directly onto the printer.
What for?: Some printers require internal cleaning to keep the printer running smoothly.
Cleaning a computer scanner:
What for?:
Flatbed scanners are usually contaminated with dust, fingerprints, and hair. When the scanner is dirty, images may be distorted.
Procedure:
Clean the surface of the flatbed scanner by spraying window cleaner on a paper towel or cotton cloth and wipe the glass until it is clean. As mentioned earlier, never spray liquid directly onto a component.
The similar towel or cotton cloth can also be used to clean the outside of the scanner.
Different cleaning steps
Below is a list of various computer equipment that is rarely used today, but this page stores people who work on older computers and need cleaning.
Disk Cleanup
What for?:
Dirty read / write heads on the drive can cause read or write errors.
Procedures:
There are two ways to clean the disk. The first way to clean the floppy drive is to purchase a kit from a local retail store that is designed to clean the read / write heads on the drive.
The second method of cleaning drives is recommended only for experienced computer users. Open the floppy drive enclosure and physically wipe the read / write heads with lint-free foam soaked in pure alcohol or trichloroethane. When performing these steps, be extremely careful when cleaning the heads so as not to align them or align the floppy drive. To avoid problems with the alignment of the head, make a slight movement, lightly applying the swab to the head and removing it, do not move the swab from side to side.
