Non-hazardous cleaning solutions and processes for cleaning blackened needles |
| abstract |
A non-hazardous cleaning solution/process has been developed for removing oxide residues from the surface of blackened needles. A low concentration citric acid solution was mixed with blackened needles and treated in an ultrasonic tank for a short period of time (<5 minutes). Oxide residues are substantially removed. Very surprisingly and unexpectedly, the penetration performance of the cleaned needles was greatly improved by up to 50% over other tested cleaning solutions. |
