If we see data cleaning as a process of detecting, diagnosing and editing data abnormalities, then we have to use all the tools in order to find those cases. The traditional and simple approach is process data and check out each variable, looking for subjects whit a significant distance respect to the central points of the distribution. These values have to be confirmed, and, in the worst case, deleted.
The data cleaning process is never ended, because of many reasons: new fields and registers would have new mistakes, data can become corrupt in any moment, and every migration or reestructuration would affect it.
