The present invention is directed to a thermal grease which is both a heat conductor and water remover. If excess heat is not removed during repair/rework operations, components of the circuit can be damaged by overheating. In an effort to avoid damage to the circuit, heat conduction greases required the use of organic chemicals and/or scrubbing both of which are time consuming, expensive and/or may damage the circuit. The greases of the present invention conduct heat, do not conduct electricity and are water-soluble. Formulations of Triethanolamine, Ethylene, Glycol Monoethyl Ether, and/or N-Methyl-2-Pyrrolidone in combination with aluminum oxide and/or zinc oxide have been found effective as water-removable heat dissipators. The following formulations by weight percent have been found effective: I.
