Ed, I totally get you! I would someday like to have my soap rotation down to around ten different jars. Which I think is very doable, when I look back over my SOTD I see that I use the same soaps over and over while the 60+ sit and collect dust. I have a few soaps that I haven't tried yet. That's wasteful.
Oils of mint or eucalyptus can be irritants for some people. When I use them, I put in half as much as I would with other oils.
