Hydrofluoric and nitric is the proven mix for pickling stainless and corrosion resistant alloys.

IPB Chemical Cleaning uses a solution of 2% hydrofluoric acid and 10% v/v nitric acid, with immersion times of typically two to four hours.

Items are rotated, inspected and re-immersed where staining persists.

Controlled, consistent pickling for oil and gas components.
