Cleaning Animal Stains
Cats may be considered one of the cleanest animals and dogs may be man's best friend, but neither is necessarily a carpet's best friend. Neglected animal stains have always been a problem. Two types of reaction can take place between the chemicals in the urine and those in the fiber dye. Some dyes change color as soon as urine comes in contact with them. Often original color can be restored by immediate addition of a weak solution of ammonia and white vinegar. Pick an inconspicuous area of the carpet and test small amounts of solution to determine its effect on the fiber and dye. The other change develops slowly over a period of several months and results in permanent change of fiber dye. Along with the dye change, some fibers become weakened or destroyed. After cleaning, these areas are more obvious because the soil, which hid the true color, has been removed.
