Caution

Cleaning also removes rust prevention oil, which may make the product more susceptible to rusting than an uncleaned product.
Please be careful about the application location and storage environment.

Product Description

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.
