How can I remove carbon build up in amplifier of my music system?

Variable resistors (potentiometers) used to adjust volume and tone etc are prone to the build up of dirt. This can sometimes cause crackles in the sound when making adjustments.

You can buy proprietary switch cleaner aerosol sprays to clean the pots - squirt and twiddle i.e. spray in a little cleaner and turn the control backwards and forwards.
