The reappearance of spots and stains is actually a very common occurrence when a carpet is
cleaned using a traditional shampoo and rinse method. Sometimes spots can reappear as soon
as the carpet dries. Let’s see how to deal with carpet stains that keep coming back.

There are two primary causes of carpet re-spotting
1. Wicking
2. Soiling


The most common cause of reappearing stains is something referred to as wicking. In these
cases the original stain has not only soiled the carpet fibres, it has also penetrated into the
carpet backing and underlying pad. Then as the moisture evaporates and the carpet dries, this
dirty water gradually wicks upward into the carpet fibres. If spots and stains reappear as soon
as the carpet dries, wicking is most likely to blame. Basically, wicking is caused by over-
wetting the carpet, backer and pad.


Soiling occurs when residue is left behind on the carpet fibres. If not completely rinsed and
blotted; it becomes sticky and attracts dirt and soil to the same spot, which can cause look
like the stain has returned.
