The present disclosure relates to multi-purpose cleaning compositions, methods of manufacturing the multi-purpose cleaning compositions, and methods of using the multi-purpose cleaning compositions to clean a surface. Beneficially the multi-purpose cleaning compositions are capable of removing soil and providing antimicrobial activity. The compositions are especially useful on hard surfaces and are preferably low streaking.

A method of detecting concentration of dipicolinic acid and terbium chloride in a chemical composition with a fluorometer, wherein the fluorometer comprises an excitation source for emitting electromagnetic radiation at one or more wavelengths, and a detector module for detecting fluorescence emitted by dipicolinic acid, emitting electromagnetic radiation from the excitation source at wavelengths that induce fluorescence in dipicolinic acid-terbium chloride combination present in the chemical composition, detecting the fluorescence emitted by the dipicolinic acid-terbium chloride combination via the detector module, and determining the concentration of dipicolinic acid using predetermined relationship between fluorescence emitted and the concentration of dipicolinic acid-terbium chloride combination.

A method of fluorometrically detecting the concentration of chemical components in oxidizing formulations is disclosed. In a particular embodiment the detection is of the stabilizing component of picolinic acid, present in such formulations, although any component which fluoresces may be detected. According to the invention sample preparation of the oxidizing formulation includes adding to said sample an excess of reducing agent to bind peracid, and in the case of picolinic acid, adding to said sample an excess of terbium chloride. The sample then is subjected to radiation to induce fluorescence and the concentration of said chemical component is determined by a linear relationship between fluorescence emitted and the concentration of the target chemical.
