First I cleaned the wrench with a brush tool to remove the loose rust.

After I put it to the container with water and baking soda in it. I also putted an iron rods with wires connected to them. Minus wire connected to the wrench(cathode).

Plus wires connected to the rods (anodes) - redox reactions (oxidation) occur on it resulting in the destruction of the anode. That is why big rods is used.

Wires connected to DC power supply 9V 5A.

This adjustable wrench appears to have been used as a hammer.

The edges were very badly knocked down.

I smoothed the edges with a file. The file allows you to grind a flat surface easily.

I have sanded the wrench with a pneumatic sand machine starting with 80 grid and up to 1000.

The thread was severely damaged by rust and cut-off by using the wrench as a hummer.

I welded up the metal and cut a new thread with a file.

I polished the wrench with a felt circle to a mirror shine and covered everything with wax to protect from rust.
