The present invention provides: a cleaning solution containing a compound represented by formula (1), a compound represented by formula (2), and water, wherein the content percentage of the compound represented by formula (2) is 0.2 mass% to 2 mass%; and an inkjet printer cleaning method using the same. In the formulas, R1 represents a linear or branched C1-C30 alkyl group. EO represents an ethyleneoxy group, and PO represents a propyleneoxy group. m and n each independently represent an integer of 1-5. m:n, which is the ratio between m and n, is at least 1:2 and smaller than 3:2. m1, n1, and L1 each independently represent an integer of at least 1, and satisfy the condition of {(m1+L1)/(m1+n1+L1)}×100>27. Formula (1): R1-O(EO)m(PO)nH. Formula (2): HO-(EO)m1-(PO)n1-(EO)L1-H. |
