OVERVIEW

Achieve a Mirror-Like Finish on Your Welds

For welders who take pride in the aesthetic quality of their work, the Cougartron CGT-550 Weld Cleaning & Polishing Fluid is the secret to a flawless finish. This high-performance fluid goes beyond simple cleaning; it is specifically formulated to polish the weld seam and Heat Affected Zone (HAZ) simultaneously. If you are working with stainless steel and need to remove that stubborn blue and rainbow heat tint without scratching the surface with abrasives, this fluid is the solution. It utilizes electrochemical action to dissolve oxides instantly, leaving behind a clean, bright surface that looks professional and pristine.

Optimized for Stainless Steel and Aluminum

Whether you are fabricating custom exhaust systems, kitchen equipment, or architectural metalwork, the finish matters. The CGT-550 is compatible with all types of stainless steel and is even safe for use on aluminum alloys. This versatility means you can keep one fluid in your shop for multiple projects. The polishing effect is particularly beneficial for electropolishing applications where a high-gloss finish is required to blend the weld bead with polished sheet or tubing.

Easy to Use and Cost-Effective

Supplied in a convenient 1-gallon jug, the CGT-550 provides excellent value for professional fabricators. It is designed to be used with a weld cleaning brush and machine. Simply dip the brush in the fluid and apply it to the weld; the chemical reaction does the hard work for you. There is no need for vigorous scrubbing or wire wheeling. The fluid is efficient, meaning a little goes a long way, and it cleans up easily with a neutralizer and water after the process is complete.

FAQ

CGT-550 is designed for electrochemical weld cleaning and polishing. It removes heat tint and oxides from stainless steel and aluminum welds while simultaneously polishing the surface.

Yes, CGT-550 is suitable for use on aluminum welds as well as all grades of stainless steel.

Yes, the fluid helps restore the passive chromium oxide layer on stainless steel, ensuring the material remains corrosion-resistant after welding.

Yes, CGT-550 can be used with all Cougartron weld cleaning machines and brush systems.

CGT-550 is used with an electrochemical machine for instant results and is generally safer and faster than traditional pickling pastes, which require long dwell times and contain harsher acids.

Yes, it is recommended to use a neutralizing fluid after cleaning with CGT-550 to remove any acidic residue and stop the chemical reaction.

This product comes in a 1-gallon container, which is approximately 3.8 liters.

No, CGT-550 is a chemical cleaner and polisher. It removes discoloration and surface oxides but will not remove physical scratches or heavy defects; those require mechanical abrasion.
