Zusammenfassung:	A cleaning solution that is used, inter alia, for removal of residue of a photoresist pattern or etching residue, and has exceptional anticorrosion properties with respect to silicon nitride; and a method for cleaning a substrate using the cleaning solution. In a cleaning solution containing a hydrofluoric acid and a solvent, a polymer that includes units derived from a compound of a specific structure having a carboxylic acid amide bond (-CO-N
