The active ingredients used in this product were cleared by the EPA for general use in the early 80's. Because someone adds a non regulated surfactant to make it foam and bubble more is nonsense. The only people touting this for efficacy/performance are bonu and the companies with shares rammed down their throat to stock it. Yes it works! But so do thousands of others entrenched. The EPA would have cleared this product for use in a day if additional products added posed no risk.
