If your calculator is exhibiting significantly slower processing speeds, in that location'due south a expert run a risk there may exist clay, grime, or corrosion on the circuit board and yous volition need to make clean it. At that place are a few different treatments for this problem depending on the severity of the outcome. Dust and dirt tin can usually exist treated with compressed air, while minor grime or corrosion tin be treated with a spot-cleaning. Significant corrosion, however, should exist treated with blistering soda.

ane
Shut down your estimator. Shut your reckoner down and unplug information technology completely from all cables. Spraying compressed air into your figurer while it's yet running can potentially damage the components and risk your own electrocution.^[1]
- Y'all tin close your estimator down by clicking on the principal menu, selecting "Close Downward," and confirming your choice on the popular-upwards window that appears.
2
Spray compressed air into the primal processing unit of measurement (CPU) in short bursts. Insert the nozzle of the compressed air canister into the fan exhaust ports, which are usually located on the back of the console at the height. Make sure to keep the canister upright as y'all spray, and spray in curt, contained bursts.^[ii] ^[3]
- Turning the canister upside-down or spraying for too long will cool the air, and can risk freezing the components of your computer.^[4]

three
Use a screwdriver to open up the CPU. Use a screwdriver to remove the screws on the back of the CPU that hold the side panel on the unit. Then, gently slide the side panel back and off the unit. This should give you access to the circuitry.^[5]
- Yous will most likely demand a Phillips-head screwdriver, but yous could potentially demand a flathead screwdriver or a hex head screwdriver instead.
four
Spray compressed air onto the circuit board. The circuit lath volition most likely be dark-green, with squiggly, silver lines on it. Spray compressed air in short bursts onto the board, keeping the canister upright and the nozzle a few inches abroad from the excursion lath. This will as well give you an opportunity to await for grime and corrosion that may require more extensive cleaning.^[6] ^[seven]
- Grime and corrosion that is particularly big or is building up almost a heat generator or on tiptop of circuit pathways should be removed.

1
Dampen a cotton swab with isopropyl alcohol. Y'all should use isopropyl booze that is at least 90%-100% alcohol. Pour a petty alcohol into a small bowl and dip the cotton swab in it. Then, squeeze out whatever excess moisture so that the swab is only lightly damp.^[viii]
- You don't want the swab to drip or exit puddles on the circuit board. Exposing the circuitry to excess moisture tin can cause damage.
2
Brush the cotton swab across the grime to dislodge it. Expect for crud that is congenital up near heat generators and on acme of circuit pathways. Lightly castor any buildup you lot find with the swab until you dislodge it.^[9]
- Exist patient rather than forceful. If you've been brushing grime for a while and you can't dislodge it, don't add together more pressure. You lot'll just to move on to using baking soda.
3
Allow the alcohol to dry. Await until the alcohol has dried. It shouldn't accept longer than an hour, usually much less. In the concurrently, you can keep brushing at particularly troublesome grime spots to try to dislodge them.^[x]
- Alcohol dries much faster than water.
4
Utilize compressed air to blow away whatsoever dislodged grime. Keep the canister upright and the nozzle several inches away from the circuit board. Spray in short bursts effectually the areas you've merely spot cleaned.^[11] ^[12]
- If you encounter bombardment corrosion or stubborn dirt that withal won't come free, you may need to use baking soda to remove it.

1
Try lightly rubbing the corrosion off with a pencil eraser. If your excursion lath has meaning corrosion on it that you were unable to remove with a spot cleaning, yous can try lightly rubbing it off with a pencil eraser.^[13]
- This is a proficient stopgap solution to avoid using baking soda, which tin cause damage to your circuit lath if non used carefully.
- The eraser method is also specially useful for cleaning circuit boards with copper components.
2
Mix together blistering soda and water and utilise to corroded areas. Mix together blistering soda and a piffling bit of water in a small bowl until you've formed a runny paste. Then, soak a cotton wool swab in the mixture and employ it gently to the corroded areas of your circuit lath until they are thoroughly covered.^[xiv]
- Yous desire the cotton wool swab to be well-nigh dripping, then that every bit much of the mixture soaks into the corroded areas every bit possible.
iii

Allow the paste to dry out for 1 day and then remove the corrosion. Await for the paste to completely dry out on the excursion board, which usually takes about 24 hours. So, dampen a cotton swab with isopropyl alcohol (xc%-100% alcohol) and squeeze out the backlog wet. Use the dampened swab to lightly castor abroad the stale paste and corrosion. Be patient and don't utilize too much force.^[15]
4
Supercede the battery that caused the corrosion. Corrosion is usually caused by acrid leaking from a battery virtually the circuit board. You should be able to find the offending bombardment fairly hands considering it will exist corroded as well. Remove the bombardment with rubber gloves, clean abroad whatsoever corrosion information technology left in the battery socket, and insert the replacement battery.^[sixteen]
- You lot can recycle your old battery by taking it to an electronics shop or recycling centre, or by mailing information technology in to a specialized recycling service (https://www.wikihow.com/Recycle-Batteries).
- The information you lot'll need to observe a replacement battery will usually exist in your computer's documentation and on the battery itself.
- If you can't find the information you need to replace the bombardment, you can put the battery in a baggie and accept it into an electronics store for identification.

No. In fact, you can even soak a circuit lath in a bath of isopropyl alcohol and you won't run into any issues. With that said, if you lot aren't conscientious y'all may accidentally knock something loose. In most cases, canned air is going to be your best bet.

Unplug the device and remove the circuit board, then pat the board dry with a lint-free cloth to remove as much wet as possible. Don't rub the board with the fabric—just gently printing the fabric over it to soak up the liquid. Advisedly remove any remaining rest with a soft-bristle toothbrush, then accident abroad dust and droppings with a compressed air tin. If there's whatever sticky liquid on the board, rinse it away with distilled water, pat it dry out with a lint-costless textile, so clean information technology with isopropyl alcohol and let it dry out completely.

Article Summary X

To clean a circuit board, try using compressed air. Just hold the tin about three to 4 inches away from the board and spray the compressed air in short bursts. This should remove grime and other build-up from the board. Alternatively, spot clean your circuit board with isopropyl booze. You'll demand to dip a cotton swab into the alcohol, and then wipe away the spots of grime. Let the alcohol dry out for an hr or and so earlier trying to use your circuit board. Remember that if you're cleaning excursion boards that are connected to a computer or other apparatus, turn the power off completely before you start.
