1. Computer shell special cleaner
First of all, we need to buy a bottle of computer-specific "cleaner", this cleaner can remove the static stains on the computer, the use of very simple - it comes with a nozzle, as long as the cleaner sprayed on the computer, printer and other equipment, such as the shell! The cleaner is easy to use - it comes with a nozzle, so just spray the cleaner onto the case of your computer, printer or other device, sponge it on, wait a few minutes, and then gently wipe off the stains.
This type of cleaner is essential for cleaning computer cases, monitors, keyboards, and other equipment that would otherwise be difficult to remove. These cleaners are generally available at counters in computer cities that specialize in gadgets, and are generally priced at no more than $20.
2. Brush with bristles
When cleaning the fan and the board on the dust, often can not be directly with a rag to sweep, must be with the help of a brush with bristles, in order not to damage the components of the premise will be attached to the components of the dust swept away.
The brush is recommended to use "brush brush", that is, with a long handle of the kind of paintbrush, it is best to choose a small, medium and large size. If you don't have one, use a used toothbrush instead, but make sure to choose one with very soft bristles, as the bristles are too hard and can easily damage the components on the board.
3. Leather tiger or hairdryer
For some of the dust, it is not easy to brush to brush, must be through the air "blown off". At this time it is best to use the blowing bag (commonly known as "skin tiger") to blow, or blow with a hairdryer cold wind block can also be.
In addition to the above tools, but also to prepare a rag, screwdriver, tweezers, eraser and other tools. Note, be sure to prepare a piece of eraser.
Keyboard cleaning method
Case cleaning (very important pineapple focus recommended)
Dust is the natural enemy of the computer, dust will lead to computer use failure, but also lead to the rise in temperature of the components, and some will be devastating to the hardware. For this reason, a major PC cleanup is a necessity, and now we'll start with the fans that are most likely to attract dust.
The common fan is divided into graphics card fan, CPU fan, power supply fan, hard disk fan several kinds, although the shape of the fan is almost the same, but the use of the fixed form may not be the same. For example, the graphics card fan may be used in a bonded way; the CPU fan may be used in a way to buckle the drama, the power supply fan is to take the integration of the way, the hard disk fan may be used in a way to fix the screws. Therefore, depending on the form of fan fixing, different measures should be taken to clean.
Before cleaning the fan, for the safety of the components, we need to perform a power failure and unplug all board devices. If it's convenient, we recommend removing the motherboard for cleaning. Some people may ask, not to say clean the fan, how to clean the motherboard went? In fact, the fan in the process of operation, will continue to blow a strong wind, so that the dust of the motherboard will run from this part to that not a part, that is to say, the motherboard is like a soccer field, a fan to kick the dust from here to there, the other also kicked from there to this, so clean up the dust on the motherboard is very necessary. Also, because of the nature of the motherboard, there are many plug spaces, and too much dust can cause poor contact in those sockets.
After taking down the motherboard, the first thing to do is to clean the inside of the case. The cleaning tool is recommended to be a vacuum cleaner and a rag to clean all the corners of the chassis one by one, and after that, wipe it with a dry rag, and if you have the conditions, use a low-efficiency cleaner effect will be more. It is worth noting that, do not use high-efficiency cleaners, which will have a corrosive effect on the chassis!
Next, put the chassis aside to dry naturally, and then put the motherboard on a thick, soft paper or hand towel. The purpose of doing so is to try to avoid damage to the solder joints on the bottom of the motherboard due to wiping. Then use a vacuum cleaner to dust the surface of the motherboard and other boards, and wipe it down with a rag a few times.
The most important step is how to clean the fans. First of all, the CPU cooler cleaning, first hold down one end of the buckle drama, press down hard so that the buckle drama will pop up, and then hand pressure on the other end, gently pull up the radiator, so that the radiator is detached from the CPU. screwdriver or manually separated from the fan and the radiator, remove the fan, you can see the fan behind the fan blades have a lot of dust, and this dust can not be accessed by our fingers, the fan blades can not be used as the fan blades, and the fan blades can not be used as the fan blades. This is because the spacing between the fan blades is too narrow. Now use a clean cotton swab to hang off the dust inside the fan blades, the dust on the outside of the fan has disappeared, for today's high quality fans, the axial part usually does not intrude dust, we do not have to take that layer of the trademark down again. The next step is to clean the radiator, due to long-term dust on its adsorption, so the radiator is much dirtier than the fan, once the dust accumulates to a certain extent, not only can not dissipate heat, but also will gather more heat.
For the radiator cleanup, we just need to put the radiator into the water to soak, thwart rub can. For radiators with complex structures, such as turbo radiators, we can't use toothbrushes, brushes, and other tools to clean them, but rather use a special tool called a "line". Wrap the thread around the radiator from end to end according to its texture, and then pull it down from the bottom, so that the dirt will stick to the thread. But for the thread, I recommend cotton thread, which has a rougher appearance and is more conducive to adhering to the dirt. That way, once it's dried, you can just screw the fan onto the radiator and install it on the motherboard to wait for the rest of the components.
The only way to deal with graphics card cooler dust is to be clever. Because the fan and radiator of the graphics card cooler are relatively small, it is not easy to get down. Especially the radiator, usually attached to the chip, more unfavorable to clean. First remove the fan from the card, either by screwing it in or by using the plastic that holds it in place from the back. After a relatively small brush for cleaning, the rag after wetting wrapped around the screwdriver, and then use the screwdriver to seep to the fan blade to clean up, so that the fan blade is not easy to get down to the place, the dust also has no place to hide. After the fan cleaning, for the radiator, we can only use a rag to clean up, here to tell you a tip, with the kind of lead wire around the rag is better, because the lead wire hardness is moderate, easier to force! After that, the graphics card cleanup is over, just let it dry and plug it into the motherboard.
For the hard disk cooler cleaning, is more complicated, the general hard disk cooler is to use the kind of closed design, it is difficult to start. For this kind of radiator, the only way is to invade the natural decomposition of alcohol, to be fully dry and then can be used normally. But a long time of immersion on the magnetic force of the motor will have an impact, generally soak 15 to 20 minutes is more appropriate, but must remember to fully dry before power, it is recommended to direct sunlight and blow dry with natural wind! In addition, hard drive coolers are generally designed with dual fans, so be sure not to forget the location between the two fans, which is the most dusty!
Power supply fan cleaning, is a very complex work, please readers must step by step, remember not to act hastily. Cut off the power supply after 15 minutes before you can do it, in turn, unscrew the screws fixed at the power supply fan, remove the power supply from the chassis. Unscrew a few fixed shell screws, from the upper part of the power supply shell, so that the internal power supply is completely exposed. We could see how much dust was attached at the fan and on the circuit board. For safety reasons, we use the balloon method (blow up the balloon full of air, and then deflate the circuit board) to eliminate the dust on the circuit board, and then unscrew the power supply fan from the fixed position, because of the limitations of the length of the power cord, it is not possible to completely disassemble the fan, so we have to be very careful with alcohol and rags to clean up, clean up the same way as the fan of other equipment, dry, the power supply is mounted back to the chassis! The power supply was tested with no payloads.
This is the end of our guide to cleaning up the radiator portion of your computer, and we hope it will give some courage to some of our friends who have never touched a radiator before. In addition, such a large-scale cleanup does not have to be held once a week, occasionally using some simple means will extend its life. Cleanup is very simple, with a linen cloth and brush cleanup can be. For cleaning up the cooling fan noise abnormally increased failure, generally because the fan internal lubricant consumption is exhausted due to the need to add lubricant to the fan shaft; there is also a possibility that the fastener is not fastened very strong caused by the fan rotation *** vibration effect. Cooling fan is indeed a wear and tear of the equipment, and because of the importance of the nature of its work, we do not recommend that you repair the damaged fan
For the host outside the computer accessories, such as monitors, keyboards, scanners, printers, etc., we have to deal with the main due to the static effect of the adsorption of dust or stains, due to the internal of the equipment is generally very precise, we only need to clean the shell of it on the line. In these devices, keyboards and mice are the most important. In these devices, the keyboard and mouse is the need to focus on the object
1. Clean keyboard
Keyboard every day with the user's hands "close contact", if the user is a netizen at the same time is a "smoker", then his keyboard is certainly not clean. The keyboard is not as clean as it should be. Therefore, in addition to good habits, regular cleaning of the keyboard is essential.
(1) Regular cleaning
Because of the special nature of the keyboard, its cleaning work should be considered discretionary: If the keyboard is only the keys are dirty, then there is no need to remove the keys on the keyboard one by one. The cleaning method is as follows - First, turn the keyboard over and gently tap the keyboard with your hand to let the dirt under those keys fall off naturally.
Put a small amount of computer "cleaner" in a bucket of water, pour in a certain amount of warm water, and then soak a towel in it for a few minutes, then wring out the towel and wipe the keys on the keyboard. Wiping the keyboard with a damp towel with a little bit of cleaner is very convenient and much faster than just using a wet towel.
(2) Unconventional cleaning methods
For very dirty keyboards, only a thorough "cleaning" can solve the problem. The specific method is as follows: Remove several fixed screws from the back of the keyboard, and then remove the plastic casing from the back until you can see the conductive plastic film inside.
The keyboard inside the conductive plastic film, circuit boards and all the keys under the rubber pads removed, placed in a clean place, this time the keyboard is only left in the shell and the keys of the plastic part of the keyboard, there is no circuitry or components. Now you can soak this keyboard flat in a bucket of water (be careful not to let the keys get out of the keyboard), fill the bucket with water and add a little cleaner to the water.
After the keys and the interior of the keyboard have been soaked in water for a while, rinse them with tap water and wipe off any stubborn stains with a rag. Wash the keyboard shell and keys completely clean and then dry them. When you are sure they are dry, reattach the rubber pads, conductive plastic film, and circuit boards in their original positions.
Note: Be sure to wait for the keyboard to dry before installing the conductive film and circuit boards, as the residual moisture may cause the internal circuitry of the keyboard to short out. In addition, this way of cleaning the keyboard after cleaning the feel will be a little worse, when you hit the keyboard a little "astringent" feeling, so if you do not need it very much, please do not easily take this "violence" means of the keyboard, especially for high-grade keyboards do not! The newest addition to the lineup is a new, more compact, and more compact keyboard.
Mechanical, photoelectric mouse cleaning method
(1) optical mouse cleaning
Now on the market we called "mechanical mouse" mouse is actually "optical mouse". It uses a roller ball to drive the X, Y two scrolling axis, the scroll has a grating wheel, a set of light-emitting diodes and a corresponding light-sensing decoder is located on both sides of the grating wheel, grating wheel rotation constantly blocking the diode to receive the light, so that the sensor can produce pulse signals.
The positioning mechanism of the optical mouse still uses the physical type of rolling ball method, so as with the traditional mechanical mouse, after a long time of use, due to the rolling ball stained, it will seriously affect the performance of the mouse, and there will be the phenomenon that the cursor moves slowly and is not positioned correctly.
This type of mouse is relatively simple to clean, the key is to remove the stains on the pulley in contact with the rubberized roller ball. There is a "screw cap" on the bottom of the mouse, which can be unscrewed to reveal the rubberized ball according to the labeling on it.
Take the rubber ball out and you'll see the scroll wheel in contact with it. If you're using a three-button mouse, there are three scrolls, so use a cotton swab (or your fingernail) to remove the stains. If the stain is difficult to remove, you can apply some anhydrous alcohol to the swab. After removing the stains from the rollers, wipe down the balls as well.
(2) photoelectric mouse cleaning
Photoelectric mouse is the current development of a very rapid type of mouse, photoelectric mouse under the ball is replaced by a light-emitting diode and photosensitive tubes, through the light reflection signal to determine the trajectory of the mouse movement. Compared to the optical mouse, the advantage of this photoelectric mouse is to further improve the accuracy and reliability of the mouse.
For no rubber ball photoelectric mouse, generally no need to often clean, as long as the shell with a rag can be wiped, do not have to disassemble the mouse.
CRT and LCD monitor cleaning
Monitor is a relatively delicate equipment, for its cleaning, many people have the wrong understanding.
(1) CRT monitor cleaning methods
CRT monitors are very large, the shell is very large naturally easier to dirty. Clean CRT monitor casing method is as follows: in the case of turning off the monitor power and unplugged, with a wet rag dipped in computer casing anti-static cleaner to wipe the monitor casing, pay attention to the foam, water can not be allowed to enter the interior of the monitor.
After waiting for ten minutes or so, wipe the casing again with a fresh rag to get rid of any stains on the casing.
For the monitor's screen, many users clean it the wrong way. Because there is a special protective coating (hard to see with the naked eye) on all CRT displays, it should never be cleaned with corrosive liquids. Therefore, never use a rag dipped in anhydrous alcohol, detergents and other corrosive liquids to wipe the screen.
In addition, even if not dipped in corrosive liquids, but also pay attention to the degree of roughness of the rag, hardness and roughness of the rag will also be on the screen of the protective layer of damage.
For the CRT monitor screen, if the top is not very dirty, just some dust, it is recommended to use a leather tiger or hairdryer (must be used "cold wind" block) will be blown off the dust; if the screen is more dirty, it is recommended to use "lens paper If the screen is dirty, it is recommended to use "lens paper" to wipe the screen - lens paper is specially used to wipe the camera lens, very delicate and soft, used to wipe the display is just right. In the use of mirror paper, finger force to be uniform, do not use finger nails to wipe, otherwise it is easy to damage the display. Mirror paper is cheap and can be purchased at camera stores.
Note: It is strongly discouraged to disassemble a CRT monitor's case to clean the circuit boards inside the monitor--although the CRT case has many heat sinks, and it is natural for some dust to enter the monitor. But this dust usually doesn't cause any major problems inside the monitor.
Because CRT monitors have up to tens of thousands of volts of high-voltage electricity inside, and even if the power supply is disconnected, there is still a residual high-voltage electricity inside, so it is very easy for an ordinary user to disassemble the casing and suffer an electric shock!
If there is a lot of dust inside the CRT monitor, and it really needs to be cleaned, it is recommended that the monitor be discharged first (using a grounded wire to contact the circuit inside the monitor, so that the residual charge is channeled into the earth), and at the same time, when cleaning the inside of the monitor, be careful not to touch any conductors, just use a brush to sweep away the dust.
(2) LCD cleaning method
For LCD, the shell of the cleaning and CRT monitor is the same. But the LCD screen is very "delicate", in addition to cleaning can not be used with corrosive liquids, but also can not use any liquid to clean the LCD screen. Because once the LCD screen into the water or was placed in a place with high humidity, the display will become very fuzzy, so do not let things with moisture into the LCD.
In the cleaning of the LCD screen, generally only the screen dust can be blown off. If there is a lot of dirt, we recommend wiping it off with lens paper or a soft cloth.
Don't remove the LCD's case, there's no need to clean the inside.
As for peripherals such as scanners and printers, you can refer to this method to clean them, so I won't go into detail here. Do not disassemble the printer, scanner, only clean their shell can be
