How to Clean a Motherboard safely (Step-by-Step Guide)

Computers are an integral part of most people’s lives. They rely on them for work, school, and entertainment. So when something goes wrong with their computer, it can be frustrating. One of the most common problems is a dirty motherboard.

Over time, dust and dirt can build up on the circuitry and cause problems. If your computer is having issues, one of the first things you should try is cleaning the motherboard.

Cleaning your motherboard regularly will help keep your computer running smoothly. Dust and dirt can cause all sorts of problems, so it’s best to nip them in the bud before they have a chance to wreak havoc.

Steps to clean any motherboard without any damage

To clean a motherboard, you must moisten a cotton swab with rubbing alcohol and gently wipe away the sticky substance.

The alcohol will help to remove the dirt and evaporate quickly to lessen the chances of electrical damage. Allow the motherboard to dry completely before reinstalling or powering the unit again. Replace the cover on the device.

Follow the detailed steps below to clean the motherboard.

Cleaning a motherboard

1. Unplug everything from your motherboard

Before you do anything else, it is important to unplug everything from your motherboard. This includes the power supply, cables, and any other peripherals. Once everything is unplugged, you can begin taking off the screws.

2. Remove all the screws

There are typically a few different types of screws holding your motherboard in place. The most common are Phillips head and flat head screws. Remove all of the screws, being careful to keep track of which goes where. Some screws may be hidden under plastic covers.

3. Take off the heat sink and fan

The next step is to take off the heat sink and fan. These are usually attached with four screws. Be careful when removing these as they can be delicate. If you are not comfortable doing this, you can skip ahead to step five.

4. Clean the thermal paste

Once the heat sink and fan are removed, you will need to clean the thermal paste off of the CPU. You can do this with a cotton swab or a lint-free cloth. Be sure to get all of the paste off so that it does not cause any problems later on.

5. Cleaning dust from the inside of your computer

Now that the majority of the components are removed, you can start cleaning dust from the inside of your computer case.

Use a can of compressed air to blow out any dust that has accumulated over time. Pay special attention to the area around the CPU and GPU as these tend to collect more dust than other areas.

There are a few different ways to clean a motherboard.

The easiest way is to use compressed air. You can purchase a can of compressed air at most electronics stores. Just make sure that you hold the can upright and spray in short bursts.

Be careful not to overdo it, as too much pressure can damage the delicate components on the board. You can also use a vacuum cleaner with a brush attachment to remove dust from hard-to-reach places.

6. Putting it back together

Once everything is clean, you can start putting your motherboard back together. Begin by replacing the heat sink and fan (if you removed them).

Then, screw in all of the Phillips head screws.

Next, replace any flat head screws that were holding down peripheral cards.

Finally, plug in all of the cables and turn on your computer to make sure everything is working properly.

Tips for keeping your motherboard clean in future

To help prevent dust buildup in the future, it is important to keep your computer case clean. Dust filters can be placed over intake fans to help trap dust before it has a chance to enter your system.

In addition, regularly blowing out your computer case with compressed air will also help reduce the amount of dust that accumulates over time.

Commonly Asked Questions (FAQs)


Which liquid is used to clean the motherboard?

Isopropyl alcohol is a common choice for cleaning motherboards and other electronics because it evaporates quickly, leaves no residue behind, and doesn’t damage most plastics.

It can be purchased at any drug store or grocery store. Isopropyl alcohol is also sometimes called rubbing alcohol.

To clean a motherboard with isopropyl alcohol, simply apply some to a lint-free cloth and wipe down the surface.

Is it OK to wash motherboard with water?

Cleaning a motherboard with water is not recommended unless you are confident in your ability to do so.

Water can damage electronic components, and unless the board is dried thoroughly, it could lead to corrosion.

It is also important to be careful about using dishwashers to clean motherboards. Some dishwasher detergents contain chemicals that can damage or corrode sensitive electronic components.

What liquid cleans a motherboard?

There are a variety of chemicals that can be found throughout the electronic assembly and repair process, but none appears more commonly than isopropyl alcohol.

Isopropyl alcohol is used as a cleaning agent because it is relatively inexpensive and does a good job of removing dirt, dust, and other debris from surfaces. It also effectively dissolves oils and other contaminants that can build up on surfaces over time.

When cleaning a motherboard with isopropyl alcohol, it is important to use a clean, lint-free cloth and to avoid getting the substance on any exposed electrical components.

It is also essential to allow the board to dry thoroughly before powering it on again.
