A Medal of Award 814 just arrived today. The strop is in a 'like new' condition. If it was used, it was very limited. There does however seem to be some kind of white treatment on the strop. Since I have NO idea what it is, I'd like to wash it out. There are also a few rounded creases in the linen. I figure once it's wet i'll lay it flat with some of my stones on it to keep it straight, then let it hang for the remainder of the drying process.

Any tips/tricks would be greatly appreciated!
