The motherboard has too much dust, can it be cleaned with water and dishwashing liquid?

After a period of operation, the mainboard, whether placed in a case or in an airtight room, is more or less dusty. If the RAM slots or expansion card slots on the mainboard are dirty, a short circuit may occur (if this is the type of dust that attracts and retains moisture), thereby damaging the slot or causing damage. the whole motherboard. Similarly, the above situation can also occur with the connection ports on the mainboard such as USB, printer port or COM port.

Meanwhile, cleaning the mainboard with a compressed air spray or a dust blower is not sure to completely solve the stubborn dust. Therefore, many users have resorted to how to wash the mainboard with water to help this component become new and clean, “clean and tight”!

Cleaning the mainboard with water properly will help clean and not cause damage to components.

Hearing this, many people will think that cleaning this way is the shortest way for us to buy a new mainboard, when few people are … ‘stupid’ to the point of washing electronics with water. However, according to some experienced users, this cleaning method is workable and safe.

How to wash the motherboard with water?

Of course, cleaning with water must also be done in a separate way, not indiscriminately. The key point of this method lies in the fact that the user must thoroughly cut off the power supply to the mainboard to avoid short-circuiting of components when exposed to water.

In addition to the obvious things such as removing the power cord and power plug, users are required to remove the CMOS battery on the mainboard (used to power the BIOS) before cleaning . Similarly, don’t forget to remove the CPU from the motherboard’s socket slot.

After completing the above two things, we can start “bathing” for the mainboard. Use a small pot, fill the pot with water so that it is just enough to cover the mainboard. In this step, users can use dishwashing liquid or solutions with less detergent, combined with water to clean the mainboard. It should be noted, you should avoid scrubbing, rubbing the mainboard with your bare hands, which can damage parts on the mainboard if you are too strong.

Need to remove CMOS battery and CPU before washing mainboard

Instead, you should use a small paint brush (dipped in diluted dishwashing liquid) to gently clean parts that are frequently contaminated with dirt such as RAM slots, PCI Express slots, PCI slots, etc. IO chip pins, Sound chip, Clock IC, power IC .vv

After washing it many times with water, we proceed to dry the mainboard. This is an extremely important step and must be done carefully if you don’t want this component to explode when plugged in because there is still water inside.

About how to do it, first, you should hold the mainboard … ‘flake’ strongly many times so that the remaining water in the southbridge chip, northbridge chip and CPU socket flows out. After that, put the mainboard out in the sun and let it dry for about 1 day.

In the absence of sunlight, you can use a high-capacity hair dryer, or place the mainboard in an air-conditioned room (turn on maximum capacity, drying mode) for a period of 6 to 7 hours. Either way, make sure the motherboard is 100% dry before installing . Finally, re-insert the CMOS battery and CPU into the mainboard, proceed to install the image in the case and start up as usual.
