Hi Billnotgatez, The TecNu Extreme product comes close to what I'm looking for.
However, it cost $2.80 per ounce. The ingredients are water, polyoxyethylene (4) lauryl ether, polysorbate 20, alcohol, silicon dioxide, carbomer, grindelia robusta extract, benzethonium chloride, aminomethyl propanol, and fragrance.
I'm looking for something simpler, that I can mix up by the gallon, without spending over $300. If I understood what chemicals work to neutralize the urushiol, that would be a start.
