Zinc coating on galvanized steel can be removed using acid solutions, vinegar, or mechanical methods like grinding and sandblasting. The right approach depends on the size of your piece, how much zinc you need to strip, and what you plan to do with the bare steel afterward. Whether you're MIG welding thick brackets, doing precise TIG work on thinner sheet, or prepping joints for stronger fusion, proper surface prep keeps your welds clean, safe, and solid. The fumes are harsh, the puddle goes crazy, and the weld ends up full of porosity.
