The one thing I noticed with liquid soap, or body wash as some are sold as is that they are more expensive then regular bar soap and they do not last as long as soap.
My gym was giving away samples of body wash and I used some. What I noticed is that I had to squeeze a good size goop onto my hands and even then, a lot of the stuff ran down the drain.
I'll stick with bar soap, because "body wash" is a scam to spend more for less.
