ABSTRACT:
A rust treatment and inhibitor preparation includes a strong acid, such as concentrated phosphoric acid, within an emulsion including wool fat or grease and derivatives. Solvents, stabilizers and absorbing agents are provided in the emulsion. The emulsion enables the acid to remove rust and protect the treated surface from further corrosion without affecting the surface finish.
