Abstract: A method of cleaning using an insonified, pressurized liquid to cleanse and then wash off particulates. The liquid is used to focus and direct the acoustical energy while enabling the trapping of the partials being cleaned and then used to wash off the partials. The acoustical frequency and power is described as optimized to be below the energy level to cause cavitation at the surface of the part being cleaned. The manufacturing process of loading, cleaning and unloading is also described. In another embodiment, a small amount of cavitation is acceptable if the cavitation is below a threshold in which shock waves occur.

Abstract: A process for restoring magnetic recording tape damaged by “Sticky Shed” syndrome cleans magnetic tapes of the Backcoating which is causing their eventual degradation and destruction. The Backcoating is first removed in a multi-step process. A liquid cleaner, such as isopropyl alcohol, is applied to the Backcoating to dissolve it from and clean it off the Mylar Base. Before the liquid cleaner is applied, steps are taken to prevent the cleaner fluid from getting onto the Oxide side of the tape. The chemical cleaning is done as quickly as possible. The second step is to dry clean the Base surface of the tape to remove the remaining solvent and the debris of any remaining Backcoating. Then, the Oxide side of the tape is given a dry, non-chemical cleaning to remove the residue of contamination of the Backcoating which was deposited on the Oxide side of the tape as the result of physical contact with the Backcoating from the storage on the reel of tape.
