    • The present invention provides a hydrophilicity-restoring agent for removing inorganic matter from a hydrophilic surface whose hydrophilicity has been reduced by the adhesion of the inorganic matter to thereby restore the hydrophilicity of the hydrophilic surface, and provides a method for restoring the hydrophilicity of a hydrophilic surface using the hydrophilicity-restoring agent. A gel of a hydrophilicity-restoring agent is prepared by mixing a thickener such as polyethylene glycol and xanthan gum with an aqueous solution in which a ligand such as citric acid to form a chelate complex is dissolved. The hydrophilicity of the hydrophilic surface is restored by applying the hydrophilicity-restoring agent to the hydrophilic surface with a reduced hydrophilicity and removing the hydrophilicity-restoring agent after an appropriate lapse of time.
