Three types of cleaning methods are available: degreasing, precision cleaning, and electrolytic polishing + precision cleaning. They can be ordered from one piece with the standard part number.
This eliminates the need for customer cleaning or outsourced cleaning, reducing the amount of time and effort required.
■Part Number for Clean & Pack Products
·Degreasing (Anti-rust single packing)    : Part Number SL-□□
·Precision cleaning (Degassing double packing)    : Part Number SH-□□
