Cleaning liquid, set, ink-jet recording apparatus and cleaning method

A cleaning liquid usable for cleaning of an ink-jet recording apparatus, the cleaning liquid comprising:

• a first water-soluble organic solvent, a vapor pressure at 20° C. of the first water-soluble organic solvent being not less than 7 Pa;
• a second water-soluble organic solvent, a vapor pressure at 20° C. of the second water-soluble organic solvent being not more than 1 Pa;
• a nonionic surfactant;
• and
• water,
• wherein the cleaning liquid satisfies the following conditions (1) to (3):
• 10≤A+B≤60 Condition (1):
• A/B≥1 Condition (2):
• (A+B)/C≥10, Condition (3):
• in the conditions (1) to (3),
• A:
• a content amount (% by mass) of the first water-soluble organic solvent in an entire amount of the cleaning liquid,
• B:
• a content amount (% by mass) of the second water-soluble organic solvent in the entire amount of the cleaning liquid, and
• C:
• a content amount (% by mass) of the nonionic surfactant in the entire amount of the cleaning liquid.
