I have a Russian finished vintage strop (made in Chicago) That I've been restoring for the last few days. I disassembled the strop to it's components and just gave the leather some strop dressing (was a bit stiff). The metal (brass?) clasp had been polished inside and out and is beautiful. The linen was almost as brown as the leather, but with some dish soap, bleach and a brush, it's cleaning up nicely (still has some spots though, can't seem to get them out). So it's about ready to be reassembled.
Is there anything I could/should do to this 'already been loved' strop to get it sanitized and ready to use...boy am I neurotic.
