Thread: Storing razor in oil filled container?

If that is happening during shaving, then that area needs to be cleaned up and polished with Maas or Flitz. You can do this with tape on the edge or polish only toward the edge. If you have a non-polished area on the blade, it will attract and hold residue and cause that kind of oxidation. Oiling over that area without first getting it polished actually increases the likelihood of staining because you are "trapping in" the very stuff you are trying to avoid.
