Traditional Dipping Method:
Usually for large production, the parts are de-greased and oil or rust inhibitor is applied on the metal parts for rust protection when shipping to the client (when no painting is done in-house).
Quality Problems:
- After de-greasing and drying, flash rust will occur on the metal surface, over which the oil or rust inhibitor is applied which covers up the rust.
- Oil or rust inhibitor does not provide long term indoor or outdoor rust protection (only for couple of months) and also has to be completely removed for subsequent operation (such as, welding or priming/painting etc.).

Picklex 20 Dipping Method:
Application:
Surface Rust removal, very long term Indoor rust protection (during shipping and storage in warehouse, store shelf, etc.) for all ferrous & non-ferrous metals
(Picklex® 20 is used as is, in full concentration)
- Completely remove oil, soil, non-metallic materials such as, rubber seal etc., from the metal surface and dry the part (let it flash rust) before dipping.
- Dip the metal in Picklex® 20 for a couple of minutes (time will vary depending on the extent of rust on the surface). Minimum dipping time is one minute.
- Remove parts from dip tank and blow off the excess product completely from the metal parts to avoid having any residue
- Air dry
NOTE:
This above Picklex® 20 Process has no rinsing, zero waste disposal and is consumed completely, no sludge, no concentration adjustment, no regular monitoring (does not lose concentration while in use), no down time. A complete “Green Process” and does not fall under any EPA or OSHA regulation. If there are a lot or parts with a lot of rust on the parts, then a pump & filtering system is needed to completely remove the rust particles from the bath (agitate the bath).
