What about nano cloth? Is it cleanable?
I’ve never tried to clean it, but I think it would difficult to remove grit from within the matrix of fibers. It’s probably like cleaning carpet – you can only get it so clean.
I didn’t mean to clean it to a near brand new state so one could apply different abrasive compound. I was rather thinking about metal particles that might eventually clog it. With diamond film I need to clean it after each use, otherwise performance quickly degrades. With leather I occasionally reapply abrasive compounds on top of what’s already on it without much cleaning. With nano I’m not sure if I can treat it like leather – add same abrasive on top of whatever’s on the strop already.
It hasn’t been an issue yet, since I only use nano to put toothy microbevels. But at some point I’ll need to deal with it, I think.
