Characteristics, Advantages & Applications
- Efficiently removes foreign substances from austenitic stainless steel surfaces and articles while preparing them for proper passivation.
- Can only be used on austenitic stainless steel as it corrodes other metals.
- Water soluble, acting quickly and thoroughly.
- Non-flammable, non-conductive and non-toxic.
- No heating is required upon application.
- No known effect on rubber or plastic compounds.
- May be combined with a specific range of other products.
- Cost effective, easy to apply and use.
During 1996, chemical tankers were only permitted to use tank cleaning agents, which had been approved and evaluated by the International Maritime Organisation (IMO). PICKLING LIQUID was evaluated through IMO’s Working Group on the Evaluation of Safety and Pollution Hazards of Chemicals (ESPH Working Group) and found to meet the requirements of paragraph 1.8.2 of the P&A Standards.
PICKLING LIQUID is an aqueous concentrated liquid mixture consisting of specific high quality acids, surface-active agents and advanced corrosion inhibitors.

Application and Use
A. Dosing Procedure
PICKLING LIQUID must be used undiluted and in quantities proportional to the extend of contamination you are dealing with, the surface area to be covered, the number of articles being treated and the type/kind of stainless steel. Anyway, the user is the one responsible to determine the actual quantity needed for each situation at hand.
B. Cleaning Procedure
PICKLING LIQUID may be applied either by the circulation or the soaking/immersion method.
However, before application, a pre-treatment process is necessary. Therefore, before commencing, clean and degrease the surfaces to be pickled with either MARICHEM ELECTROCLEAN SUPERFAST to remove felt pen ink marks, oils and light carbon deposits or with MARICHEM ALCACTIVE LIQUID to remove grease deposits that have accumulated on smaller metal surfaces and parts. Afterwards, use a high-pressure water supply to rinse well.
Circulation is a method mainly used for pipe systems. Here, the system is filled with PICKLING LIQUID, which it must be circulated for 2-6 hours depending on the degree of soiling and the type of the austenitic steel. Do not pickle longer than is necessary. Thereafter, drain the system and rinse thoroughly with water. Passivation must follow immediately. Note that before disposing of the liquid, it must be neutralized with slaked lime.
Soaking/Immersion is a method used for parts, components or other articles. The process is initiated by filling a plastic or plastic lined bath with PICKLING LIQUID. Then, place the articles to be pickled into the bath and leave them to soak for 1-6 hours depending on the degree of soiling and the kind of austenitic steel. Remove the articles from the bath and spray them with a powerful water jet. Passivation should follow immediately after spraying.
In any case, note that before disposing of the liquid effluent solution, it should be neutralized with slaked lime.
PICKLING LIQUID is considered highly corrosive. Operators must consult the Safety and Handling instructions table before use.
