Abstract of the Disclosure A method of de-hazing distillate fuel is disclosed which comprises adding to the fuel a solution of a halide salt dissolved in an alcohol, and an alcohol soluble organosiloxane. The halide salt may be the chloride of magnesium, cadmium, copper, nickel or the tetra methyl ammonium group, for example the salt may have the formula MgC12.6H20 or (CH3)4NCl. The organosiloxane may be a cyclic, linear or branched material and may have e.g. a minor amount of siloxane units having the general formula (i) Image and a minor amount of siloxane units having the general formula (ii) Image in which each R represents a substituted or unsubstituted hydro- carbon group of up to ten carbon atoms, a has the value 0, 1, 2, or 3, b has the value 0, 1 or 2, c has the value 1 or 2, and each Z represents a group linked to the silicon atom and compri- sing a functional organic group. Each group Z may be a group selected from the polyoxyalkylene group R1(OCH2CH2)p(0CH2CH.CH3)r0R", the amine group R'NHQ, the quater- nary ammonium salt R'NR23X, the carboxylate group R'C02M, the sulphonate group R'S03M, or the hydroxyl group, in which R' represents a group which provides a link to the silicon atom through an oxygen or a carbon atom, p has a value in the range 1 to 100, r has a value in the range 0 to 50, the sum of p and is in the range 2 to 100, R" represents a hydrogen atom, an alkyl group or an acyl group, Q represents a hydrogen atom or a group R'NHQ, each R2 represents an alkyl group, X represents a halide ion and each group M represents a cation.
