The invention discloses an overbased metal cleaner grease comprising at least one polyalkylene glycol and / or an acid having at least one of nitrogen and sulfur atoms. According to the Standard Test Method for Measurement of Extreme-Pressure Properties of Lubricating Grease (four-ball method), ASTM D2596, this grease has improved extreme pressure performance.n n n The present invention discloses a method for manufacturing an overbased metal cleaner grease, which comprises using at least one polyalkylene glycol and / or an acid having at least one of nitrogen and sulfur atoms. A method of using the grease to lubricate a mechanical component includes contacting the mechanical component with the grease. Mechanical components may include gears, transmission elements, bearings, hinges, or a combination thereof. |
