so i buy this soap because i shoot pretty often and i have two young kids. i read some studies that it does significantly better at removing lead compared to just regular soap.
however, it's fucking expensive.
how do i find out what the chemical in it is responsible for removing lead from skin?
i figure if it's some relatively common chemical, i could just order it online, and add it to whatever soap i wanted to.
