Abstract: A cleaning liquid includes water, a surfactant, and glycol ether. The surfactant is an acetylene surfactant or a silicone surfactant. A content ratio of the glycol ether is at least 5% by mass and no greater than 15% by mass relative to a mass of the cleaning liquid. Preferably, a contact angle of the cleaning liquid to an austenitic stainless steel plate is no greater than 40 degrees.

Abstract: An ink set includes an inkjet ink and a recording head filling liquid. The inkjet ink includes a pigment, a pigment coating resin, a first alkali metal ion, and water. The recording head filling liquid includes polyethylene glycol, a second alkali metal ion, a surfactant, and water. The polyethylene glycol has a mass average molecular weight of at least 180 and no greater than 800. A content ratio of the surfactant in the recording head filling liquid is greater than 0.00% by mass and no greater than 0.10% by mass. The first and second alkali metal ions each contain at least one of Li+, Na+, and K+.

Abstract: An ink set includes a water-based ink and a water-based cleaning liquid. The water-based ink and the water-based cleaning liquid each contain at least 1.0% by mass and no greater than 4.0% by mass of a deliquescent agent. The water-based cleaning liquid further contains a nonionic surfactant and a diol. The deliquescent agent that the water-based ink contains and the deliquescent agent that the water-based cleaning liquid contains each include at least one of sorbitol, trimethylolpropane, and 1,3-bis(2-hydroxyethyl)-5,5-dimethylhydantoin. The nonionic surfactant has an HLB value determined by Griffin method of at least 14 and no greater than 16. The diol includes at least one of triethylene glycol and 1,3-propanediol.

Abstract: An ink for ink-jet recording apparatuses, includes water, a pigment dispersion, and a super-penetrating agent and a high SP organic solvent respectively having a predetermined solubility parameter (SP value). All of differences (ΔSPs) between SP values of the neighboring organic solvents are from 0.5 to 5.0 in order of SP values thereof, and the difference of SPmax−SPmin is 12 or less in which SPmax is the highest SP value of an organic solvent among organic solvents in the high SP organic solvent and SPmin is the smallest SP value of an organic solvent among organic solvents in the super-penetrating agent.
