Abstract
A technique for cleaning a hard disk using a novel support device 502. The technique includes immersing a disk in a liquid comprising water. The disk has a front face, a back face, an edge, and a center region. The method also includes providing a substantially particle free environment adjacent to the front face and the back face as the liquid is being removed. A step of introducing a carrier gas comprising a cleaning enhancement substance during the providing step also is included. The cleaning enhancement substance dopes the liquid which is attached to the front face and the back face to cause a concentration gradient of the cleaning enhancement substance in the attached liquid to accelerate fluid flow of the attached liquid off of the disk.
