Steam cleaning is the only truly effective method. It is capable of reaching the deepest parts of a carpet and can remove all stains, bacteria, hair and dirt from carpets. When your carpets start to look like they've had better days, you might wonder if it's time to buy new ones or if you should try to save the ones you currently have. It's always cheaper to repair than replace, but there will be some cases where it will be necessary to buy new carpets.
A general rule of thumb is to replace carpets when they present health risks, such as mold or allergens. However, if your carpets have only a few stains, you can probably get professional cleaning help to return them to their original splendor.
Carpet
cleaning, in general, is tedious and time consuming. Every centimeter must be sprayed, rubbed, rinsed and dried.Professional-grade equipment and techniques remove deep dirt and embedded stains, as well as efficiently extract water and solvents used in cleaning. Home cleaning methods are more likely to leave residues. This persistent residue then traps dirt particles. A dry cleaning solution (with very low humidity) for carpet maintenance goes a little further than the typical routine of a vacuum cleaner.
If you haven't, you should research both methods before deciding how you want them to be used on your carpets. On the one hand, a professional carpet cleaner will know how to check the upholstery and backing of carpets for possible mold growth and will ensure that carpets are cleaned until they reach their upholstery, where mold could be growing. However, most carpet owners only clean their carpets once every few years (and some don't even that). A design, such as a waffle-like fabric pattern or a checkerboard pattern, can be created along the surface of the rug using different lengths and hair styles.
There is the dry foam method, which consists of washing carpets with shampoo and removing the shampoo after it has completely dried. When fibers are flattened due to foot traffic, cleaning reactivates the hydrogen molecule, causing the fibers to literally recover. Unlike sprays and dry cleaners, steam cleaning a carpet will not inject substances that may leave residues in the carpet fibers. Steam cleaning is a truly effective and efficient way to remove the build-up of carpet fibers, including mold and pet scents.
Not only do you not see the carpet underneath this large piece of furniture, but it's not exposed to air, light, and foot traffic like the rest of the carpet is, so it makes sense that it doesn't need to be cleaned as often. The opening of this design and the twisted ends of the thread allow the strands of this type of carpet to sink underfoot, creating a soft feel and a somewhat irregular appearance on the surface of the carpet. Environmental factors can also influence how often carpets should be cleaned and the effectiveness of a standard vacuum cleaner for that cleaning. There's nothing wrong with calling local cleaners and asking them what situations they can handle when in doubt.
There aren't many reasons to avoid cleaning the carpet, but there are some methods that can sabotage the health of the carpet and wallet.
