You clean it with Dielectric Cleaner, you can get it at most automotive stores like Advance Auto, I've also heard of an old trick using a pencil eraser to clean the surfaces.
To effectively clean Citristrip from brushes, you can use mineral spirits or paint thinner. Soak the brushes in the solvent for a few hours, then rinse them with warm, soapy water. Repeat the process if necessary until the brushes are clean.
I had a problem with my a/c fan. I took out the glove box and accessed the ac blower motor(on the passanger side). unbolt and remove. take a look at the motor brushes they may be covered in black. take the motor apart and clean brushes and contacts. Put everything back and it may work. It worked for me.
You should clean acrylic paint brushes with warm, soapy water.
Motor brushes ride one the commutator.
check the brushes and bearings in your motor make sure you have a good ground and the connections are clean but most likely the motor is shot
Carbon
To clean acrylic paint brushes effectively, first rinse the brushes in warm water to remove excess paint. Then, use a gentle soap or brush cleaner to wash the bristles thoroughly. Gently reshape the bristles and let the brushes air dry. Repeat the process if necessary until the brushes are clean.
The normal number of brushes is 2.
the reason for brushes is to makethe motor revolve. The more brushes probably make a more powerful starter motor
Carbon is much stronger and because the motor commuter is spinning copper brushes will wear off quickly.

An alternative to carbon brushes in an AC motor is using a brushless motor. Brushless motors have permanent magnets and electronic drive systems to operate, eliminating the need for brushes or commutators. This design results in less maintenance, higher efficiency, and longer lifespan compared to motors with carbon brushes.
