Thread: Grease residue on the razor after shaving. What is this?

Hhhm, thats true for a lot of acids.
I use the bathroom cleaner for my soap kitchen and there is a lot of steel.
I have never seen anything like a stain from using it.
It just cleans excellently.

No its probably just mild enough.
Will try on a carbon steel and let you know.

After shaving I rinse and wipe the blade and strop a few times on linen, then reapply the oil (Ballistol is my choice.)

+1 on oiling the blade. I use mineral oil, since that is in my bathroom already. Aside from these benefits, the lightly oiled blade conditions my strop.
