  • First, unplug the device from any power source
  • Next, use a vacuum cleaner with the brush attachment to remove any dust or debris from the surface of the circuit board
  • Then, use a cotton swab dipped in isopropyl alcohol to clean any remaining dirt or grime from the circuit board
  • Be sure to avoid using too much pressure, as this could damage the delicate components on the board
  • Finally, allow the circuit board to dry completely before plugging it back into a power source and turning it on again

Is It Ok to Clean Circuit Board With Alcohol?

You may have heard that cleaning a circuit board with alcohol is a bad idea. And while it’s true that you should avoid using rubbing alcohol or isopropyl alcohol to clean your circuit boards, there are other types of alcohol that are perfectly safe to use. Grain alcohol, also known as ethyl alcohol, is the type of alcohol found in alcoholic beverages like beer and wine.

It’s also the type of alcohol used in many cleaning products. When diluted with water, grain alcohol is an effective cleaner for most surfaces, including circuit boards. If you’re going to clean your circuit board with grain alcohol, be sure to dilute it first.

A 50/50 mixture of grain alcohol and water is usually sufficient. Apply the mixture to a lint-free cloth and gently wipe down the circuit board. Avoid getting any liquid on the electronic components themselves.

Once you’re finished cleaning, allow the board to air dry completely before powering it on again. Whilegrainalcoholis generally safe forcleaningcircuitboards, there are some exceptions. For example, if yourboardhasanyplasticcomponents(such as insulation), it’s besttoavoid usingalcohol altogetheras it can cause thosecomponents toturn yellow or brittle over time.

Can You Wash Circuit Boards With Water?

Yes, you can wash circuit boards with water. However, it is important to use distilled water instead of tap water. This is because tap water contains minerals that can damage the circuit board.

Also, be sure to dry the circuit board completely before using it again.

What Liquid is Used to Clean Circuit Boards?

When it comes to cleaning circuit boards, there are a few different liquids that can be used. The most common is isopropyl alcohol, which can be found at most hardware stores. Another option is distilled water, which can also be found at most grocery stores.

Either of these liquids will work fine for cleaning circuit boards.

How Do You Clean Dusty Circuit Boards?

When it comes to cleaning dusty circuit boards, there are a few things you’ll need to keep in mind. First, you’ll want to make sure that you disconnect the power source before beginning. Once the power is disconnected, you can begin by gently brushing away any dust or debris that has accumulated on the board.

Be careful not to use too much pressure, as this could damage the delicate components. If there is stubborn dirt or grime that won’t come off with a brush, you can try using compressed air to blow it away. If this still doesn’t work, you can try lightly dampening a cloth with distilled water and wiping down the board.

Again, be careful not to use too much moisture, as this could damage the components.

Once you’ve cleaned off the visible dirt and grime, it’s time to disinfect the board. This is especially important if the board has been exposed to any liquids, as they can often leave behind harmful bacteria.

You can disinfect the board by wiping it down with a solution of equal parts distilled water and isopropyl alcohol. Allow the solution to dry completely before reconnecting the power supply and powering on the device.


If your computer or other electronic device is starting to act funny, one of the first things you should check is the circuit board. Usually, when a circuit board gets dirty, it just needs a good cleaning. Here are some tips on how to clean your circuit board at home.

First, you will need to gather some supplies. You will need a can of compressed air, cotton swabs, and isopropyl alcohol. You will also need a clean work surface and plenty of ventilation.

Once you have all of your supplies, turn off the device and unplug it from any power source. Take off any covers or panels so that you have access to the circuit board. If there are any removable parts, such as memory cards or hard drives, remove them as well.

Now it’s time to start cleaning. Use the compressed air to blow away any dust or dirt on the surface of the circuit board. Be careful not to use too much pressure, as this can damage delicate components.

Next, dip a cotton swab in isopropyl alcohol and use it to scrub away any stubborn grime or residue. Again, be careful not to apply too much pressure while scrubbing. Once you’ve finished cleaning the circuit board, put all of the covers back on and reassemble the device.

Plug it in and turn it on – hopefully everything will be working like new again!
