There are a range ways to clean your carpets naturally, including vacuuming regularly with a vacuum equipped with a High Efficiency Particulate Air (HEPA) filter. “Cleaning using chemicals is mostly unnecessary on carpet,” notes Alex Varela, General Manager of Dallas Maids, a house cleaning service in Dallas, Texas. “What you need is consistency when it comes to vacuuming. You need to do it at least twice a week, although every other day would be ideal.” But you also need to eventually deal with stains and odors that get set in and your vacuum can’t handle. “Carpet is made out of hundreds of fibers that are highly absorbing. This material is prone to several types of bacteria and viruses. It’s one of the types of flooring that harbors bacteria the most,” adds Varela. “This is because carpet absorbs organic matter all day: hair, skin cells, dandruff, and food and beverage spills or residues. This is the place bacteria and viruses feed on, lingering both on the floor and in the surrounding air.” As with any carpet or fabric cleaner, always do a spot test in an inconspicuous area to ensure the product won’t change the color or damage your carpet or other fabric. We found the best carpet cleaners that rely on mostly natural ingredients, including sprays, powders, and shampoos to remove stains, odors, and grime.

FAQs Can you use vinegar to clean a carpet? Yes, white vinegar mixed in equal parts with warm or hot water can be used to remove stains and odors from many carpet types without harming fibers or changing their color. The vinegar leaves a faint scent that dissipates when the carpet is dry. However, using undiluted vinegar on wool, silk, or some other natural fiber carpets can damage the material so be sure to dilute it properly. As always, spot test any cleaner in an inconspicuous area first to ensure no damage will occur. Are there any cleaners or chemicals consumers should avoid? “Definitely avoid ammonia or any cleaning products that use ammonia, because they might stain your carpet. Plus, the smell is very strong so it won’t be a good idea for allergic people,” advises cleaning expert Alex Varela. “Also, bleach is not a good idea either, for the exact same reasons. It might cause staining and release toxic gases, especially when mixed with other chemicals.” Consumers should also avoid synthetic fragrances, naphthalene, and acrylic acid. Synthetic fragrances are made from toxic petroleum- and coal-based chemicals that have a number of documented negative chronic health effects. Several cleaners also use naphthalene because it is effective at dissolving dirt but is also known to cause cancer and are toxic to the aquatic organisms even after passing through standard sewage treatment. Acrylic acid is added to carpet cleaning solutions because it coats carpet fibers with a protective layer similar to plastic that prevents future stains. Both naphthalene and acrylic acid have earned an “F” from EWG. Are there any homemade solutions that work for cleaning carpets? “For any homemade solutions that you try, remember to test in an inconspicuous area first,” says Valera. “I would say that baking soda is usually an effective, harmless solution. It works for most couches and carpet floors. What you want to do is sprinkle a bit over the surface, let sit overnight and vacuum the next day.” Why Trust Treehugger?
