The present disclosure relates to an additive for a multi-use oil-based flame-resistant organic fluid for safely releasing corroded joints and fasteners and other general use purposes. The oil-based organic fluid includes a flame-resistant additive such as a carboxylated aromatic compound, which has a self-extinguishing effect on an arc of flame. The inclusion of carboxylated aromatic compounds release carbon dioxide when heated, causing the material to extinguish itself during ignition to resist catching on fire.
