Frequently Asked Questions: Weld Cleaner

What is weld cleaner?

Weld cleaner refers to systems and solutions designed to remove oxidation, heat tint, discoloration, and residue from welded metal surfaces. Electrochemical weld cleaners use electrical current combined with cleaning solution to create a chemical reaction that removes contamination and restores the metal's natural appearance. This technology is particularly important for stainless steel welding where heat tint affects both appearance and corrosion resistance.

What is the best way to clean a weld?

The best way to clean a weld is using an electrochemical weld cleaning gun that combines DC electrical current with specialized cleaning solution. Connect the cleaning gun to your weld cleaning machine, dip the carbon fiber brush in cleaning solution, clamp the ground wire to your workpiece, and lightly brush over the weld seam. This method is faster and produces superior results compared to grinding or chemical-only approaches.

What chemical removes welding marks?

Electrochemical weld cleaning uses specialized solutions containing weak acid components such as phosphoric acid or citric acid combined with electrical current. The current and chemical work together to dissolve oxidation layers and restore the passive chromium oxide layer on stainless steel. After cleaning, always rinse with clean water or neutralizing solution to prevent corrosion residue.

What do you clean metal with before welding?

Before welding, clean metal surfaces with acetone, isopropyl alcohol, or dedicated pre-weld cleaners to remove oils, grease, dirt, and contaminants. Proper pre-weld cleaning ensures strong weld penetration and reduces porosity and defects. Use clean, lint-free cloths and allow solvents to fully evaporate before striking your arc.
