Citric Based Passivating Agent
Citric Based Passivating Agent
(OP)
I am needing to clean and passivate some significant quantities of 316 s/s on an offshore platform in the Timor Sea. The usual HF and HNO3 based pickling pastes are considered too hazardous and environmentally unfriendly to use and wash overboard. I believe there may be a citric based product which may be useful for mild levels of contamination after removal of contaminated areas with a flapper wheel or wire brush. Can anyone please advise the name of a commercially available and environmentally friendly product?

You might also consider vibratory burnishing.
