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