| 20080202562 | Method of cleaning firearms and ordnance - A composition for removing copper from a surface comprises a polyphosphonic acid, a primary amine, and water. Optionally, the composition may also comprise a dialkanolamine and/or a trialkanolamine, a degreaser, and/or a surfactant. The pH of the composition is between 9.0 and 12.5. The method of removing copper from a surface, which may be a gun bore, involves contacting the surface with the composition. | 08-28-2008 |
| 20090020142 | METHOD OF RINSING ENDOSCOPES - The method is a method of rinsing an endoscope in an endoscope cleaner placed in a vessel. The method includes a step of charging a surfactant into a vessel in addition to water to fill the vessel with a first rinse water containing the surfactant, a step of rinsing the endoscope placed in the vessel with the first rinse water, a step of supplying only water into the vessel after rinsing with the first rinse water to fill the vessel with a second rinse water that does not contain the surfactant and a step of rinsing the endoscope with the second rinse water. In the method, the action of the surfactant contained in the detergent is effectively utilized in a rinsing treatment of the endoscope while the endoscope is rinsed to thereby ensure that re-deposition of dirt is suppressed to enhance the overall cleaning efficiency. | 01-22-2009 |
