To clean your fabric second strop, try warm water, Woolite and a toothbrush. Then let it dry naturally laid flat. For stubborn staining, you might try spray carpet cleaner. Woolite makes this product also.
Treat your fabric gently because it is designed for delicate razor edges.
As someone just stated, Dovo paste is designed to create drag and TI is designed to remove steel. Choose wisely..........
