Removing weld discolouration or paint from stainless steel
You remove weld discolouration or paint from stainless steel by removing only the top layer. This leaves the weld and the shape of the workpiece intact. Which product you choose depends on the shape of the workpiece and your budget.
Which product suits your workpiece
Choose based on the workpiece: a flat, easily accessible surface or an irregular shape. Looking for an affordable solution? Then there is the BRIS10009.
FAG
Ideal for removing weld discolouration without affecting the weld.
- Low aggressiveness
- Also removes paint and coatings
- Smooth and even finish
Cibo Bristles
Ideal for paint or discolouration on irregular and hard-to-reach surfaces.
- Safer than steel wire brushes
- The impact of the bristles removes paint and discolouration
- Flexible bristles follow the shape of the workpiece
BRIS10009
Affordable choice for removing paint or discolouration.
- Causes no deformation of the workpiece
- Less safe than Cibo Bristles

Frequently asked questions about removing weld discolouration or paint from stainless steel
What is weld discolouration on stainless steel?
Weld discolouration is the coloured oxide layer (yellow, blue or brown) caused by the heat of welding. In that zone, the protective layer of the stainless steel is affected, making the material less resistant to corrosion there.
Why should you remove weld discolouration on stainless steel?
Without treatment, the area around the weld can start to rust. Removing the discolouration allows the protective layer to restore itself, so the stainless steel stays corrosion-resistant. The workpiece also looks neat.
Do you choose grinding or pickling to remove weld discolouration?
Pickling is a chemical process with acids and strict environmental regulations. With the Rebel One F-line, you remove weld discolouration mechanically in one step, without acids. This is safer and easier on the shop floor.
Which product do you use to remove weld discolouration or paint from stainless steel?
The FAG unitized disc is our choice: it grinds cool and with low aggressiveness, so the weld stays intact. Cibo Bristles remove paint or discolouration through the impact of the bristles. The BRIS stainless steel wire brush is an economical alternative.
