I have one of those strops which I got NOS. It is a very dark red color. Once the linen is properly cleaned it should have a grey tone to it not pure white.

Saddle Soap should be avoided. The stuff was developed for very thick and tough leathers like...saddles and really tough boots. It will dry out and remove the color and vital stuff in most leather when used over and over. I know many here love the stuff but it is what it is.

Bick is great stuff both the cleaner and and conditioner. If you want the bees knees in leather care get some leatherique. If anything can turn a worn stop into something looking new it's that product. The bad news is its super expensive like $100 for the kit but it can be used for all leather.
