Hello everyone, I am new to the community and new to straight blade shaving. I am about to shave with a straight blade for the first time. I have two quick questions. Does stropping need to be done immediately after shaving or can I do it before the next shave? The other question is when I'm done shaving do I clean out the mug with all the lather or do I leave all the un-used lather with the soap in the mug?

Thanks in advance, Paul
