This is most often a result of wicking which will be discussed below.
After i clean my light carpet the dirt comes back.
If the spot is not dried quickly such as with the use of fans the residue wicks back up and again a returning spot after carpet cleaning.
Removing these stains from carpet or upholstery especially stains that have set in over time and keep returning to the surface can be frustrating.
These stains occur if there is too much cleaning solution and water used during the cleaning process.
This is common when carpets are steam cleaned.
At other times the spots and stains come back after the passing of a few weeks.
You may notice brown stains on your carpet after a thorough carpet cleaning.
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.
Additionally choose a reputable professional to clean your carpet.
After cleaning a spot or stain from your carpet there are times where it will return just shortly after the carpet dries.
The stain then becomes visible again.
This sticky soap attracts more dirt and grime which cause the stain to reappear.
So whenever you clean the carpet the surface might be cleaned but the carpet continues to absorb the moisture and the contents to the back of the carpet.
Good professional cleaners have the proper equipment to extract the moisture from the carpet leaving it almost dry.

Begin by removing furniture from the room and then thoroughly vacuum the carpet preferably with a powerhead vacuum cleaner before shampooing to remove loose dirt pet hair and other.
This deep staining will eventually be pushed back up the fiber strands to the surface again and this is wicking.
Pet accidents red wine tomato sauce or coffee stains can be notoriously difficult to completely clean up after a spill.
If spots and stains reappear several weeks after your carpet has been cleaned excessive soap residue is most likely to blame.
The solution for spot cleaning returning spots is to applying the spotter to a towel instead of directly to the carpet re clean the area using less moisture.
When the carpets dry the stain comes right back to the top.
Keep in mind that the liquid causing wicking can also be from the chemicals and cleaning water left behind during manual cleaning and when a cleaning is machine used not just the spillage liquid itself.
This is most often referred to as rapid resoiling.
Prepare your carpet and areas to be shampooed.
