A clean-up fluid for cleaning fluid-carrying apparatus is described. The clean-up fluid comprises a liquid, typically water, and sufficient particles in admixture therewith to initiate a cleaning action in use within a fluid-carrying apparatus. Particles of fibre are dispersed in a volume of the liquid in an amount that does not exceed the particle carrying capacity of the volume of liquid. A cleaning method and a method of transporting aggregate materials using the clean-up fluid are also described. |
