    ZincChloride flux is obtainable in the UK under the Baker’s Fluid brand. It should be washed off after soldering because it will continue to corrode the base materials. It should never be used on electrical joints as it could wick up inside the wires and lead to unseen corrosion. The proper flux for stainless steel is Phosphoric Acid . I suggest that the two bits of “Stainless” soldered together were actually chromium plated and you can solder this with the flux shown.

      Not to strong I would say 20-25% even a bit lower. If it's too strong it will eat your copper soldering tip very quickly. Use solder with the highest tin content you can find. To much lead is no good. I use 94% tin 6% silver to soft solder stainless and it works well

    Thanks! I am from India. Now 70 +, in my teenage days I used to watch a Kerosene Stove repairer near my house doing soldering jobs. I used to collect old Dry cells, preferably of Estrella make, and give him. He used to give me few Paisa, enough for me to buy a Candy or Ice cream. I have seen him using the Battery case as seen in this Video while soldering. Although he used a soldering rod with a heavy Copper tip, which he used to heat with a Kerosene burner. Now I know the exact reason for the Zinc case.

      Oxigen reacts first with Zn and it is consumed so remains nitrogen from air as inert gas to protect the soldering zone. HCl clean the oxidazed surface of the solded metal. In cas of aluminium is different, Al reacts with oxigen before Zn and Al2O3 is more compact.

      Aluminium can’t be soldered ‘as is’ because it reacts with oxygen in the air to form a protective layer of aluminium oxide which is non-metallic (it’s the same as alumina ceramic!). Sanding it breaks through the very thin layer of oxide to expose the metal. Applying the oil isolates the metal from the air and prevents re-oxidisation allowing the solder to alloy with the aluminium and ‘wet’ it. But the oil must be applied immediately the sanding is ended as the aluminium re-oxidises very rapidly.

    60/40 lead solder or 97/3 Sn/Ag solder are OK for electrical joints and low stress mechanical joints. The 97/3 solder is some 50% stronger than 60/40 solder.
    If using a zinc chloride flux such as Bakers Fluid on mechanical joints, I neutralise with sodium bicarbonate solution.
    High strength joints on stainless steel can be done using silver solder 55/45 Cu/Ag. Use proprietary flux which contains flouride. Have to heat to red heat, usually with a butane torch but oxy acetylene can be used using care not to over heat.
    Akuminium can be soldered using proprietary alloys such as Lumiweld, which require no flux at all. However aluminium soldered joints are not very strong. For strong joints have to AC TIG weld them.

    Use standard acid flux, even vinegar on the surface or scratch up the surface with sand paper to remove surface oxide and then apply flux and then solder. It's all about removing the surface oxide in any way you can. Remember to wash off any acid/chemical you applied after soldering or it may cause long term corrosion to the area.

    Before the days of modern non-corrosive soldering fluxes, zinc chloride solution was the standard flux, either purchased or home-made as in this video. Non-corrosive fluxes gained popularity as soldering of electrical and electronic components became more widespread, but as mentioned elsewhere in the comments, it’s still available in the form of Bakers soldering fluid.

    A file and some silver solder can work wonders. Plus, solder won't stick if the part isn't getting enough heat.
