Abstract
A cleaning composition of high chemical activity with anti-fungal properties, and with low dry weight residue and particularly useful for cleaning the surface of phonograph records; the mixture includes a surfactant, an emulsifier, an anti-microbe or fungicide, all intermixed in a liquid carrier such as water. This composition is most effective when used in combination with a brush designed having a cloth cover whose projecting filament form a pile that is finished and maintained angularly, and which when brushed against this pile effectively loosens dirt particles from the phonograph record surfaces being treated. In the method of use of this invention, the cleaning composition may be applied to the leading edge of said brush pile, with the brush then being moved simultaneously across and with a rolling action upon the surface being cleaned, as for example, the phonograph record surfaces, thereby effectively cleaning the disc of lipids, dust particles, and fungal particles that may clog and/or be germinating in the microgrooves of the same.
