Nutek Green introduces Bolt Off, a powerful, fast-acting, penetrating lubricant. This formula helps reduce the friction from metal on metal rust and corrosion, creating a lubricated surface to loosen and move even the toughest stuck together components. Bolt Off is specially formulated to provide a long-lasting residual effect, and lubricates long after applied. This soy formulation is 90 percent biodegradable, and made in the USA.
