To provide a maintenance liquid and maintenance method which can eliminate discharge failure of an ultraviolet curable ink jet printer.SOLUTION: A maintenance liquid is a maintenance liquid for an ultraviolet curable ink jet printer, and contains a first composition which can dissolve a water-soluble compound and does not dissolve a cured product of the ultraviolet curable ink. A maintenance method is a maintenance method of the ultraviolet curable ink jet printer, and includes a first cleaning process S3 in which the water-soluble compound adhering to an ink jet head included in the ultraviolet curable ink jet printer is dissolved with a first maintenance liquid containing the first composition which can dissolve the water-soluble compound and does not dissolve the cured product of the ultraviolet curable ink, and a second cleaning process S1 in which the ink jet head is cleaned with a second maintenance liquid containing a second composition which does not dissolve the water-soluble compound and can dissolve the cured product of the ultraviolet curable ink.SELECTED DRAWING: Figure 16 【課題】紫外線硬化型インクジェットプリンタの吐出不良を解消するメンテナンス液及びメンテナンス方法を提供する。【解決手段】メンテナンス液は、紫外線硬化型インクジェットプリンタのメンテナンス液であって、水溶性化合物を可溶で、かつ紫外線硬化型インクの硬化物を不溶な第1の成分を含有する。メンテナンス方法は、紫外線硬化型インクジェットプリンタのメンテナンス方法であって、紫外線硬化型インクジェットプリンタが備えるインクジェットヘッドに付着した水溶性化合物を、水溶性化合物を可溶で、かつ紫外線硬化型インクの硬化物を不溶な第1の成分を含有する第1のメンテナンス液で溶解する第１の洗浄工程Ｓ３と、水溶性化合物を不溶で、紫外線硬化型インクの硬化物を可溶な第２の成分を含有する第２のメンテナンス液でインクジェットヘッドを洗浄する第２の洗浄工程Ｓ１と、を含む。【選択図】図１６
