2.
Hold the circuit board or any other electrical appliances about 15 - 20centimetres away and spray a generous amount of WD-40 Specialist® Contact Cleaner onto the surface.

Let the solution sit for a couple of seconds until it is completely dry.
Tip! To check if it is dry, use the tip of your finger to lightly dab the surface to see if any remnants will stick to your finger.

Check if the parts are all clean and repeat if necessary before inserting them back into place, for dust-free circuit boards!
