Developed by Ensitech, TIG Brush is the result of years of innovation and research in metal surface finishing. At its core is our patented Dynamic Power Transfer® technology, engineered to maximise cleaning power across all operating conditions – ensuring fast, reliable results whether you’re handling large-scale industrial work or fine, precision welding.
TIG Brush systems are trusted globally for their ability to:
- Remove weld discoloration and oxides quickly
- Passivate stainless steel in a single step
- Protect and extend the life of metal surfaces
- Minimise user effort and environmental impact
Paired with our environmentally responsible cleaning fluids, TIG Brush offers not only superior performance but also a safer, more sustainable choice for modern fabrication.
Today, Ensitech continues to lead the way in stainless steel surface treatment – trusted by professionals across manufacturing, construction, food processing, pharmaceutical, and other demanding industries worldwide.
Our Story: Innovation Born from Necessity
TIG Brush’s origins are rooted in solving a real-world industrial challenge. In the early 2000s, Clive White, one of Ensitech’s founders, was approached by a friend working on a major project for McDonald’s. The task? To manufacture a stainless steel charity panel with a coin chute for donations. While the panel needed a polished, brushed finish, the welding process resulted in a common but stubborn issue-heat tint, which discolored the steel and destroyed the aesthetic finish.
Traditional methods of removing heat tint were inefficient and often damaged the material, leading Clive to use his background in electronics to find a better solution. Together with a friend, an aeronautical engineer, Clive developed a revolutionary new cleaning method that used electrical current and safe cleaning fluids to quickly and safely eliminate heat tint without damaging the steel surface.
This breakthrough led to the creation of the first TIG Brush units. Designed specifically to clean and restore the surface of stainless steel welds, these early machines were an instant success with local manufacturers, and the technology quickly gained traction across the industry.
What began as a solution to a specific problem has grown into a global brand synonymous with quality, safety, and efficiency in metal surface cleaning. TIG Brush continues to evolve, leading the way in innovation for metal surface finishing, and helping industries worldwide meet the highest standards of quality and precision.

Extensive laboratory testing has confirmed that Ensitech’s weld cleaning process passivates stainless steels in accordance with ASTM International standards. The intense heat generated during the welding of stainless steel causes oxidation and chromium depletion in the alloy's surface layer, as well as unsightly heat tint around the weld area.
Independent testing by Gauge Industrial and Environmental, using a Scanning Electron Microscope (SEM), has shown that cleaning with a TIG Brush and genuine TIG Brush fluids removes all detectable oxides from the weld zone, and returns chromium levels in the surface layer to greater levels than found in the original unwelded surface.
The tests found that cleaning with a TIG Brush produces results superior to pickling paste, along with the greater safety of TIG Brush technology. These results have also been confirmed by an independent passivation report conducted by The Welding Institute (TWI) in Cambridge. A key finding of the report concluded: “All the TIG Brush chemical variants studied improve the corrosion resistance of a welded sample, such that the corrosion rate is reduced to below that of unwelded steel.”
Weld cleaning fluids are used during the TIG Brush electrochemical weld cleaning process. The weld cleaning fluid is designed to be safe at room temperature, but aggressively removes the heat-tint found on stainless steel welds after TIG and MIG welding.
Ensitech manufactures a range of weld-cleaning fluid products catering for different user needs. The range of fluids also includes pre-welding fluids for the removal of surface corrosion or contamination before welding takes place. Each weld cleaning solution has a corresponding neutralising solution, which brings to an end the weld-cleaning process and prevents white residues from forming later.
The optimal combination of weld cleaning fluid products will depend on the type of weld being cleaned, the safety regulations of the industry, and what priority is placed on cleaning speed versus degree of finish.
Yes, weld cleaning solutions are safe to use provided they are used in accordance with the manufacturer's recommendations and with the appropriate PPE.
Ensitech's weld cleaning fluids are NSF approved, meaning they are safe to use even in the stringent food industries. The fastest weld cleaning fluids are acidic, but are safe to use when used according to recommendations.
For the safety-conscious, there is a pH-neutral fluid, which is completely safe and low risk. The wide range of weld cleaning fluids caters to different customer needs, giving you the confidence that you are able to select the best fluids for your particular application. You should have no qualms using Ensitech fluid range as a part of your TIG Brush weld-cleaning process.
As a precautionary note, you may run into safety issues when using “pickling pastes” to clean stainless-steel welds, as these usually contain hydrofluoric and/or nitric acid. If you are using pickling paste to do weld cleaning, consider switching to the safer, scientifically proven Ensitech electrolytic weld cleaning fluid products as soon as possible.
If you take pride in your work and require fast, safe stainless-steel weld cleaning, then you should choose Ensitech cleaning fluids for your TIG Brush.
Ensitech cleaning fluids have been designed to assist in every aspect of stainless-steel cleaning and surface preparation.
