Some liquids like wine, dark juices, and coffee can leave noticeable stains on your home's carpet. Even if you soak up as much of the liquid as possible and try to spot-clean the stains, you will eventually need to do a deeper clean to get rid of them.

However, even if the stain disappears when you use a steam or wet-dry vacuum cleaner on them, you may find that they eventually return no matter how many times to try. Below are some answers to questions about why your carpet stains keep returning as well as what you can do to get rid of them for good. 

Why Do the Carpet Stains Keep Returning Even after You Use a Cleaner on Them Multiple Times?

The main reason why the stains on your carpets keep returning even if you use a cleaner on them multiple times is that liquid and its pigments can become trapped at the base of the carpet fibers. Even if the surface stain is removed, the fibers will pull the liquid and pigments up from the base through a process known as wicking.

Over time, the fibers' wicking action will pull the staining materials back up to the top. Depending on how much residue is present, this process can take a few hours to a few days. 

What Can Be Done to Permanently Remove the Carpet Stains?

After finding out why the stains keep returning, your next question is probably how you can get rid of them permanently. To do so, you will need to hire a professional cleaning service since the carpet-cleaning solutions and equipment that you have access to will not be enough to fully get rid of the residual liquids and pigments stuck at the base of your carpets.

However, a professional will use commercial-grade cleaners to dissolve the residue. They also have powerful cleaners that will pull it out without damaging your carpets.

Even if you use a steamer or carpet cleaner on the stain, the wicking of any liquid found at the base of the fibers will make it keep returning. While you may be able to get most of the residual liquid out of the fibers using a store-bought cleaner, it can only be thoroughly removed by a professional carpet cleaner with access to commercial-grade cleaning solutions and equipment. If you have one or more stains that keep showing up on your home's carpets no matter what you do, call a professional carpet cleaning company to make an appointment.
