Shea butter is a vegan butter used, in between other uses, as a scalp hair anointing material; it's the most thick creamy-ointment I personally have known and can help straighten quite curly hair; it can be putted on hair in two or three "waves" and then the hair is combed.
My problem
After some people use Shea butter with their hand palms, their hand palms become very cream-oily.
Removing it from hand palms might require using lots of soap (when using a squared firm soap) and about two towels; to split the cream evenly and not to ointment one towel too much (in the span of a few days) and possibly also about two or four napkins to remove pointed leftovers.
One can afraid that so much wiping, small particles from certain towels or napkins could contaminate the skin tissue of its hand palms and would desire an efficient way to remove Shea butter from hand palms.
Possible solution
Because removing it from scalp hair requires a strong (quite salty) shampoo and lots of wash, I assumed that a strong (quite salty) liquid soap, instead squared firm soap, could be handy.
My question
How to safely and efficiently remove Shea butter from hand palms?
That is to ask; how could Shea butter users as described above, safely and efficiently remove it from their hand palms (in the means of liquid solution and wiping appliance material)?
Update
With time I found it helpful to use different common generic shampoos or liquid soaps to do go work.
I further found that in general, the more a professional shampoo or a liquid soap is more salty (in a chemically reasonable amount) the more it is effective.
I can buy a large ("saving") pack of some shampoo and use a little bit of it, with or without some soap (probably liquid but not necessarily).
