Cleaning composition

A liquid marine cleaning composition which in water-diluted form is sprayable onto the walls of cargo holds, wherein the composition consists essentially of:

• (a) from 5 to 50% by volume of an anionic surfactant having a log10P value in the range 5 to 7;
• (b) from 10 to 45% by volume of a first non-ionic surfactant having a log10P value in the range 0.1 to 3 and having the general formula, R′-(AO)n-OH, wherein R′ is C9 to C20 alkyl, AO comprises at least one —OCH2CH2 group and at least one —OCH2CH(CH3)— group, the molar ratio [—OCH2CH(CH3)—]/[—OCH2CH2—] is in the range up to 8 and n is greater than 6;
• and
• (c) from 10 to 45% by volume of a second non-ionic surfactant having a log10P value in the range 0.1 to 3 and having the general formula, R′—(OCH2CH2)n—OH, wherein R′ is C9 to C20 alkyl, and n is less than 6,
• each of said volume percentages being with respect to the total volume of (a), (b) and (c), wherein the composition has a pH of from 6 to 9.
