Today I came across this vintage strop. The case is shot, but the handle and leather are quite sound. (Photo shows both sides of strop.)



The only trouble is that the surface of the leather (free of nicks, etc.) has kind of a greasy feel. Not oily. As if some conditioner had been put on it many years ago. It's not something I like.

I would like to get back to the leather and then use it for pastes, Chromium Oxide for right now. I will paste the other side later if I feel like it. I really like this strop and would hate to ruin a very nice bargain.

What do you recommend? Some cleaning agent or a particular grit sandpaper (e.g. 600+)?

Thanks in advance for your help
