Biodegradable VCI-422 Liquid Rust Remover 

VCI-422 will remove rust without attacking the base metals. They will leave an almost "white" metal surface even when removing heavy rust. Light rust stains can often be removed in a few minutes. Medium rust may require a 24 hour treatment, while heavy rust treatment somewhat longer.

VCI-422  has been used to remove corrosion products from stainless steel prior to the application of a Clear permanent rust inhibitor coating for protection against atmospheric pollution such as chlorides and sulfates, which can also attack stainless steel.  

These products can be put into a tank if you wish to immerse the part. For removal of heavy rust, this may be the best method. Heat will accelerate the rust removal as will mechanical scrubbing.

VCI-422 is a very safe product, and will not normally cause any problems.

It is nontoxic, non-hazardous, non-fuming, nitrite free and biodegradable.   USDA and FDA  Approved !

However, some people may be unusually sensitive and should use gloves. Goggles should also be worn to keep the product out of the eyes.  After treatment, the surface should be rinsed with clean, drinking quality water.  VCI-422 does provide flash corrosion protection, (short term rust prevention) however, it does not provide  corrosion protection once it is washed off. Therefore, further treatment is necessary after removal rather quickly.  

Possibilities for such treatment include: wrapping in a VCI film or bag, oil,

temporary or permanent coatings, or painting of the area.

Life of the solution is dependent on the amount of rust.   

The primary chemical residue is iron.
