Hi.

Just been shaving for some months with the straight. I love it, but thereīs this issue that got me thinking.
When I finish I take a look at the razor, and there it is: some kind of dirt (maybe grease from the skin?), and itīs difficult to get rid of. I go over the strop but it remains there, so I end up wiping it out with a tisue and LOTS of caution so that I donīt damage the edge.
Whatīs this, guys? How do you get rid of it? Maybe someone asked about this before, but I donīt know how itīs called so the search function wasnīt helpful.
I have a couple of photos for you to see what Iīm referring to. Here, have a look:
