I have found that if I

  1. wash the blade off with very hot water
  2. blow the scales out
  3. wipe with a towel and leave unfolded while I clean up
  4. wipe a small amount of oil on the blade from a Japanese knife oiler and put it away folded.

This eliminated my spotting.

To eliminate what is already on the blade you can use 0.5 or 0.25 diamond paste. I have found anything else a little harsh and leaves some scratches.


Take Care,
