Method and apparatus for cleaning an interior volume of an electrical component are provided. The apparatus includes a housing with vacuum pins extending from apertures in the housing. The vacuum pins are arranged and sized to fit through ventilation holes in a chassis of the electrical component. The vacuum pins are individually retractable so that a vacuum pin that encounters a structure in the interior volume of the electrical component does not impede remaining vacuum pins from further entering the volume. A vacuum source is attachable to the housing and applies a vacuum to the interior volume through the vacuum pins.
