Gordon H Posted August 19, 2015 Share Posted August 19, 2015 This is it. Works well. It's Phosphoric Acid. Take care. Maybe it does, but it's not something that would normally be used for electrical work, which is what this sub forum is about. For building loco kits and other mechanical work certainly...

chaz Posted August 20, 2015 Share Posted August 20, 2015 Utter madness. Just buy ordinary cored solder. I did see the results of someone who habitually used phosphoric acid for soldering wires to solder tags - which are plated steel. the only other way I know to get such corrosion on steel is to dip it in sea water. Not nice. However for soldering brass kits together phosphoric acid is my first choice but it must be neutralised and washed away. CIF cleaner (alkali) will neutralise it and plenty of running water will flush the CIF away. If you need to add flux to an electrical joint Fluxite is a safe bet - it's the same type of flux that is used in resin-cored solder. Hope that's helpful.
