Unscrewing rusty threaded connections (Focus 2)

Before installing the wrench on a heavily rusted nut, clean the exposed threads from dirt and corrosion.

1. Clean the threads with a wire brush and apply a penetrating compound to the threaded part.

2. When using a fast-acting compound, begin to loosen the nut immediately after applying it.

3. When using a slow-acting compound, begin disassembling the unit after the penetration period has elapsed.
