Collect 10 to 20 liters of processing fluid in a bucket/container.
Add the following amount of W-2K to the collected fluid ① and mix.
Immersion-type machine: about 0.2 to 0.5% of the machine’s total tank fluid
Flushing-type machine: about 0.5 to 0.6% of the machine’s total tank fluid
Pour the diluted fluid ② into the tank.
Circulate for about 20 minutes to make the concentration uniform.
Note: When rust prevention effectiveness later decreases (timing varies depending on usage conditions), add 5 to 10% of the amount of W-2K added in step ② to the tank.
