The Ranger Pro product label actually states "spray solutions of this product should be mixed, stored and applied using only stainless steel, aluminum, fiberglass, plastic or plastic-lined steel containers." The manufacturer does prohibit the use of this product with galvanized steel or any other steel other than stainless steel. You should check with the manufacturer of your sprayer to be sure that the metal parts on your sprayer are stainless steel.
