Inventive methods, systems and compositions of cleaning integrated circuit (IC) substrates are described. The cleaning methods of the present invention include: charging a solution, which contains at least a solute selected to promote cleaning of the IC substrate, to produce a charged solution, such that at least a portion of the solute is present as clusters in the charged solution; and conveying the charged solution for cleaning the IC substrate. The cleaning systems of the present invention include: a charging chamber for holding a solution, which contains at least a solute selected to promote cleaning of the integrated circuit substrate; and a first acoustic energy source capable of vibrating the solution in the charging chamber to produce a charged solution such that at least a portion of the solute is present as clusters in the charged solution. The cleaning compositions of the present invention include: a solvent; and a solute selected to promote cleaning of the IC substrate, wherein at least a portion of the solute is present in cluster form in the solution and the solute and solvent are present in a volumetric ratio that is between about 3×10−5:1 and about 1×10−24:1.
