I make a lot re-batched extra scrubby bars from old shavings, old soap etc. What I do is weight out the amount of shreds I need and pour over a some liquid, and let them sit overnight to start softening up. I am talking enough to kinda coat the shreds not let them sit in liquid. When re-batching I use liquid castile or any of my liquid soap I have on hand. I find it helps facilitate the melting down and makes a harder bar by the next day. I am not saying do this and take to market, but it makes quite a difference in the hardness of the rebatched soaps. Even my hubby notices the difference. Sometimes I still add in some yogurt, milk, water, etc but I always use some LS. Sorry I do not weight out my liquids I just go by how the soap is melting down.
