I found the solution to the drying film of butternut squash residue! You know, the stuff on your hands that Stays there?
After cubing two large butternut squashes, my hands were covered with the super-gluey residue that comes with the job. What couldn't be washed off with soap and nail brush remained, a thin, drying, cracking, totally annoying film. Forget trying Lava, facial peach pit exfoliant, olive oil, alcohol.
One day later and after no success Googling the issue, I tried the pumice tool that is made for removing foot calluses. Ta-Da. Follow with lotion. ( In the future, I may try using gloves to avoid the problem)
