Though numerous companies claim they can clean up bad credit reports, correcting erroneous information that may appear on credit reports takes time and effort.

Individuals are entitled to free credit reports every 12 months from credit reporting agencies, as well as when an adverse action is taken against them, such as being denied credit based on information in the report.
