Thesolder strip is probably something akin to silver which has longsince tarnished and won’t solder reliably. The solution :- Rustconverter. Also comes in the form of Navy Jelly. Rust converteritself is available in two forms. One a watery liquid the other atype of varnish. You want the liquid form. Rust converter isphosphoric acid. Shock horror acid on electronics. Don’t panicstay calm. Don’t go crazy with it just smear enough to do the jobon the metal strip and solder in the usual way.. I use a small softart brush. Clean up with soap and water and finish off with clearwater. demineralized if you have it. Rust converter is good forcleaning PC boards for etching , reconnecting old wire and cleaningjust about anything that won’t solder. Works on nickel and chromeas well as for treating rusted steel.Ifyou don’t have any rust converter on hand use coco cola. It is rustconverter with added sugar.
