Maintaining your home stereo or car audio system will ensure proper operation and good sound quality. Oxidation present on cables and connections will inhibit signal transfer between audio devices, causing unwanted distortion, crackling and possible malfunctions. The presence of high humidity, dust particles, liquids and oils increase the chances of oxidation, regardless of the connection's material type. Cleaning cable connections and speaker wire terminals for your home or car audio systems is an easy task, provided you have the appropriate cleaning materials on hand.
