A visual indicating paste composition for detecting of aqueous solutions in hydrocarbons by changes in color. The paste is utilized by placing on a probe and inserting the probe in a storage device for fuel. Said paste comprising:a) a liquid carrier selected from high molecular weight polyols;b) a caustic powder selected from alkaline earth oxides;c) a gelling agent;d) a surfactant consisting of ethoxylated nonylphenol with 9 moles of ethylene oxide;e) a filler material.f) a water scavenger consisting of aluminum isopropoxide;g) an indicator dye; andh) a neutral dye;wherein the paste of the present invention will change color upon contact with an aqueous solution in the pH range of about between 7 and 11.
