This I have done so many times I probably have no new skin left to grow.
The main items I have use are REAL aloe pulp and Desitin to keep a wound moist to soften the dead flesh.
Then if possible I will cover the arm leg or whatever with plastic wrap it keep the are moist and warm which hastens the removal of dead skin.
The item of choice for me to get all the nastiola off right away a green quality scrub pad, not the chinese stuff it is no good.
I cut them into piceces big enough to hold easily and scrub quite hard to remove as much as I can.
Soaking after in the hot tub with the salt bath will really help out anyway it helped me out a lot.
