The most common cold solvent operation, this is usually used in small maintenance degreasers using a petroleum or mineral solvent. Usually to remove the bulk of the material, and prepare it for the cleaning tank. Although if the part does not need to be perfectly clean, then the operation can be ended after spraying.
The solvent to use is dependent on two factors: the agent that is causing the stain, and the material that has been stained. Different solvents will dissolve different stains, and the application of some solvents is limited by the fact that they not only dissolve the stain, but also dissolve the material that is stained as well.

Silicone grease is soluble in organic solvents such as toluene, xylene, mineral spirits, and chlorinated hydrocarbons. It is insoluble in methanol, ethanol, and water. [2] Thermal grease often consists of a silicone-grease base, along with added thermally conductive fillers. It is used for heat-transfer abilities, rather than friction reduction.
Grease fitting on a bearing A grease nipple on the driver's door of a 1956 VW Beetle. A grease fitting, grease nipple, Zerk fitting, grease zerk, Alemite fitting, or divit is a metal fitting used in mechanical systems to feed lubricants, usually lubricating grease, into a bearing under moderate to high pressure using a grease gun.
Dry lubricants or solid lubricants are materials that, despite being in the solid phase, are able to reduce friction between two surfaces sliding against each other without the need for a liquid oil medium. [1] The two main dry lubricants are graphite and molybdenum disulfide. They offer lubrication at temperatures higher than liquid and oil ...
Filters remove most odors and particulates, including grease, from the vented air. There are three main types of filter: Mesh or cassette filters are made from aluminium mesh strips placed one over the other. They are highly effective in the capture and removal of oil and grease from smoke of both ducted and ductless chimneys.
Grease is a solid or semisolid lubricant formed as a dispersion of thickening agents in a liquid lubricant. Grease generally consists of a soap emulsified with mineral or vegetable oil .
The ground-glass rim of the desiccator lid must be greased with a thin layer of vacuum grease, petroleum jelly or other lubricant to ensure an airtight seal. In order to prevent damage to a desiccator the lid should be carefully slid on and off instead of being directly placed onto the base.
