Many household chemicals like acne medication, detergents, deodorizers,
disinfectants, hair sprays etc. containing bleaching agents coming in
contact with your carpet/rug may cause bleaching action on the dyes present
in the carpet fibers. The result may be stains ranging from white to light
yellow, pink and beige.
To prevent these stains, hands must be washed carefully after using any
of these chemicals. Once bleached, these stains are permanent and require
redyeing to treat them. The bleaching action may have the undesirable
side effect of weakening the carpet fibers too.
