Yes, you can use alcohol swabs soaked in isopropyl alcohol (70% V/V) to clean electronic components such as a processor or motherboard. Isopropyl alcohol is often used to clean this type of equipment because of its fast dissipating properties and its ability to remove dirt, grease and thermal residue.

However, before using an alcohol pad to clean electronic components, be sure to take the following precautions:

Turn off and unplug the unit or system before starting to clean.
Use anti-static gloves to avoid electrostatic discharges that could damage the components.
When cleaning an electronic component, avoid applying excessive pressure as this may damage the components or circuit boards.
Ensure that the alcohol evaporates completely before replacing the component or reconnecting it to the unit.
For hard-to-reach areas, use a cotton swab soaked in isopropyl alcohol.

Finally, it is important to note that the alcohol swabs mentioned are designed for medical use, and may not be as effective as those specifically designed for electronic cleaning. Be sure to check the manufacturer's information to ensure that the product is suitable for your intended use.
