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; 
it's no hazardous liquid, so heavily personal protection is not neccesary; 
Bio-deruster even removes bluing and other oxide finishes (Anodizing will not be removed);
it's no rust-transformer; so no layer stays behind.

Bio-deruster is a perfect aternative for:
derusting thin or rare parts that are very difficult to sandblast; 
compannies with high environmental care companies working according ISO14000


Bio-deruster is a liquid in wich the object has to be soaked in order to get fully derusted.
First preclean the object to remove heavy dirt and grease.
Rinse the object.
Immerse the rusty object in sufficient amount of Bio-deruster and leave it for about 20 minutes for light rust, or up to overnight for extremely heavy rust.
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. 
The color will change from light yellow to very dark.

To prevent flash rusting, dip the item back into the Bio-deruster. Then allow it to air dry. This will prevent rust for up to two weeks.
