Penetrating oil

BiRAL PO penetrates rapidly and very deeply into the innermost, normally inaccessible parts of rusted and seized components.


Normal applications will free seized items in a few minutes.


In extreme cases it is advisable to spray the component two or three times over a period of 20-30 minutes, allowing the PO to penetrate deeply, before attempting to loosen the item.


Surface accretions of rust can be removed by spraying, allowing to soak for a few minutes and then gently removed by rubbing with copper or soft metal pads, emery paper or similar abrasive agents.
