It depends on what kind of trace it is Is it a dent, scratch, or stain? The methods of removal are different! !
The poster is probably referring to the weld area; generally, this can be eliminated after pickling and passivation.
What the original poster is referring to are the marks resulting from collisions during manufacturing. The method of repair depends on the depth and size of these marks; for example, larger and deeper marks should first be ground before being polished, while smaller marks can be removed simply by polishing them first, followed by acid cleaning and passivation.
It should be treated in two different ways: for traces and spatter left after welding, use acid washing and passivation; for areas with more severe traces, grind them followed by polishing. 2 For food hygiene – grind and polish.
