A stain is a discolouration of any surfance on which it may be found. It may be intentional or accidental. It is caused by the chemical interaction of two or more differing materials. Stains are caused when a substance is spilled onto a surface and the fibres absorb the colour. Stains may be thought of as accidental in some circumstances, whereas 'dyes' are considered permanent. Some stains may be removed by the application of suitable chemicals
