DIY Soldering Flux Paste Make Using AA Batteries

Może zamiast cały dzień kroić baterie wrz szczotkę druciana albo pilnik i wyczyść rdzę

Flux. He made flux. It's like $0.99 a tin. Ridiculous.

Kelamaan, wayer gunting keci kecil campur air batrai bekas tunggu bentar hingga larut lalu oleskan sama juga tak harus kaleng sama prostex

He literally used a grinder to cut open the battery when he could've used it to remove the rust and the solder will stick. I don't think his flux had anything to do with it. Besides bakers flux is safer.

It appears to be a fake video. Do not even give try to make it. Would have felt real if he soldered same rusted surface with his so called “flux”
