A method of cleaning waste water and removing contaminants therefrom with respect to compositions exhibiting water sol- ubility behaviour which is pH dependent. The method includes the preliminary step of applying the composition at a pH at which the composition is water insoluble, then removing excess composition from application equipment with a wash solution having a pH at which the composition is water soluble or washable, changing the pH of the wash solution to a pH at which the composi- tion is water insoluble to thereby precipate the composition and removing the composition by filtration or other separation tech- niques. The invention also relates to a shop towel clean up method.
