Abstract: An ink-like cleaning solution for cleaning an inkjet print head installed in an inkjet printer and having deposits of ink, includes: a viscosity agent for adjusting the viscosity of the ink-like cleaning solution; a surfactant for adjusting the surface tension of the ink-like cleaning solution; a cleaning agent for breaking down the deposits of ink; and a solvent miscible with the ink, in which the viscosity agent, the surfactant, and the cleaning agent are dissolved or dispersed. The viscosity and the surface tension of the ink-like cleaning solution are equivalent to those of the ink used for printing with the inkjet print head such that the inkjet print head can print on a media using the ink-like cleaning solution under conditions for printing.
