Principle
Grease stains can be dissolved out by treating them with petroleum ether. With coloured textiles, the colour-fastness of the material must be tested on an inconspicuous part prior to stain removal. Halogenated hydrocarbons are favourized because of their solubility for fats, but their use is ecologically of concern als well as being a health hazard. Organic solvents are highly inflammable.Try to remove a grease stain from a linen cloth.
