Jerry Avins expounded:

Denature the irritant on yourself and your tools with a moderately
strong alkali. Brown laundry soap (which contains some of the lye used
to make it) was once recommended, but it's hard to find and household

Fels Naptha soap is what you're referring to, and oldtime home
centers still carry it. It works well.
