When should I use vacuum grease?
Vacuum grease is a lubricant with low volatility and is used for applications in low pressure environments. Lubricants with higher volatility would evaporate, causing two problems: They would not be present to provide lubrication. They would make lowering the pressure below their vapor pressure difficult.
How do you clean high vacuum grease?
The best I have done is paper towel wetted with acetone, a quick wipe against a quickfit joint, and bang, its clean (enough). I suppose if you had conditions where even *slight* contaminants would ruin your reaction, you would have to try to solvate the grease.

Which of the following lubricant can be used in a high vacuum?
Tungsten Disulfide It has a coefficient of friction of 0.03 and offers excellent dry lubricity under conditions of load, vacuum and temperature. It can also be used in high temperature and high-pressure applications.
Is vacuum grease needed?
Grease is most commonly used with glass vacuum systems. All metal systems usually use knife-edge seals in soft metals instead. Where O ring seals are used, these should not be greased (in static seals at least) as it can cause the O rings to become permanently distorted when compressed.
How do you dissolve vacuum grease?
Any residues of grease can be washed away with warm soapy water or by using any aromatic hydrocarbon solvent (toluene, xylene). For a more environmentally friendly solvent, we recommend limonene. They cannot be cleaned using alcohols (ethanol, IPA) or ketones (acetone, MEK).
Which is the best solvent to dissolve grease?
Grease: Tougher to Dissolve Try mineral spirits first to remove grease stains, then if necessary, perchloroethylene, which is a better grease solvent and dries fast.
What is vacuum grease soluble in?
Solubility. DOW CORNING High-Vacuum Grease is insoluble in water, methanol, ethanol, acetone, glycol and glycerine. It can be dispersed in kerosene, stoddard solvent, benzene, toluene, ethyl ether or petroleum ether.
