Saratoga Gold Fluid One, GFO, although a technical product for general maintenance, has several useful applications in agriculture for maintaining machinery, tools and equipment exposed to weathering. It is not a product for organic farming or for direct plant treatments, but an 8-in-1 multifunction lubricant and release agent. It dissolves rust and encrustations from nuts, screws, bolts, hinges and mechanical couplings on tractors, trailers, ploughs and seed drills that are blocked or seized.
