A flexible cleaning tool for cleaning corrosion from the contact arms and barrel of electrical jacks of the type frequently used in guitar amplifiers and public address systems. A low density polyethylene shaft is inserted into the jack and manipulated by moving the handle, whereby the flexibility of the shaft allows the shaft to bear upon the jack contact arms and jack barrel interior in a manner which is highly conducive to efficient and thorough cleaning. The dislodged corrosion attaches to the shaft allowing the corrosion to be transported from the interior of the jack enclosure where it can be easily washed from the shaft.
