You don't have to stay with the process, so it saves manpower; 
because the object is soaked, the deruster comes to places you normaly never reache;

Bio-deruster is a liquid in wich the object has to be soaked in order to get fully derusted.

Check progress periodically. When finished, rinse te object in water. 

If deep rust remains in pits, re-immerse the object untill al the rust is gone. 
Un-rusted metal will not be affected! It may darken.

Bio-deruster can be used over and over until performance drops off. It can take about 3 grams pure rust per ltr.
