Nutcracker is a unique multi use fluid, and is specially formulated for New Zealand requirements to be both a penetrating and lubricating oil as well as a machining compound. Unlike many other penetrating fluids, the anti rust component is non toxic, giving Nutcracker a pleasant sweet odour.
To use as penetrant on heavily rusted nuts and bolts, spray it on, let it sit for a while, then try to turn the nut or bolt. Once it breaks free, work the thread back and forth, spraying more Nutcracker on as required. Use it the same way to tap and die.
As Nutcracker does not contain vegetable or animal based products, it is much more stable and less likely "to go off" producing malodorous odours. Nutcracker comes in a manual dispensing bottle rather than an aerosol container, which could have the potential to explode when overheated. Nutcracker is MAF approved C23, and deemed to be non toxic.
