Sometimes stains that have been hidden by soil are revealed after cleaning. These stains, which did not immediately discoloration, are usually from spilled liquid containing colourless sugar that remained on fibres. After long exposure to the air, they changed to insoluble brown stains. The stains may look like brownish discolorations but often remain unnoticed because of the accumulated soil covering them.
Other kinds of stains can be caused by water soaking through and absorbing sizings, browning or fugitive dyes from the backs of the material. Because the fibres act as wicks, moisture will rise to the surface to evaporate, and discoloration will be left. Consumers who try to remove stains by using wrong cleaning compounds and procedures, may only make the stained areas more noticeable.
To lessen the possibility of stain damage, immediate action should be taken: thoroughly absorb all moisture and, when possible, put a ½ inch thickness of clean white absorbent material over the area, weighing it down – then call your professional cleaner to learn how to remove the spot safely before it becomes a permanent stain.
