It’s a new spot that was created due to incomplete spot cleaning. Some other reasons spots come back after carpet cleaning have to do with the natural layering of carpet and “the wicking effect”: The residue left behind from spot cleaning causes new soil to stick, an issue in high-traffic areas.

The same spots appear to come right back, but in reality it is mostly new soil that becomes stuck to the detergent residue within the carpet fibers. If spots and stains reappear several weeks after your carpet has been "cleaned", excessive soap residue is most likely to blame.Apr 15, 2013

What is the first stain?

The first kind of stain we mentioned is actually referred to as soiling. This is when some of the cleaner used to treat the stain is inadvertently left behind. As such, although the stain was likely cleaned, the leftover cleaning solution remained on the spot. Therefore, after time had passed, the cleaner quickly collects dirt and grime so the spot became dirty once again.

What is the second type of stain?

The second type of stains reappearing is referred to as wicking. This is when the stain has soaked into the lower fibers and carpet backing–or even possibly the flooring beneath. Often, when cleaning the carpet, only the top part is cleaned. So while the stain appears clean in the moment, the stain slowly rises up the carpet fibers. This action is similar to what happens with a candle wick which is where it gets the name!

1. Wicking

Stains that reemerge due to wicking originate beneath the carpet fibers. The original stain has not only stained the carpet fibers, but it has also infiltrated the carpet backing and underlying pad in many circumstances.

2. Residue

The stains that reoccur as a result of residue come from within the carpet fibers. Some of the shampoo, soap, or other cleaning products used in a standard cleaning technique may have been left behind in your carpet in these circumstances. The residue will linger even after the carpet has dried.

3. Mold

Mold is the least common reoccurring problem, but it’s also the easiest to notice. Mold is almost always caused by a lack of moisture. To grow mold, you’ll need a wet carpet. Mold typically emits a unique odor. There is no need to go into detail about this issue because of its rarity and ease of detection.
