Professional carpet cleaning leaves two things behind to manage: gases from cleaning products and detergent left in the fiber. The EPA lists household cleaning products as a source of volatile organic compounds, or VOCs. The Carpet and Rug Institute (CRI) says leftover detergent makes carpet re-soil faster. A rinse step and fresh air handle both. Xtreme Cleans does not claim zero VOCs or zero residue.
Xtreme Cleans is a carpet cleaning company serving 12 Maryland counties plus Baltimore City. This guide defines both terms, states what each one does to a home, and explains what a visit includes to limit them.
Does professional cleaning help with VOCs and low-residue cleaning?
Professional cleaning helps when it ends with a rinse. A VOC is a gas released from a liquid or solid, and residue is cleaning product left in the carpet; a rinse step addresses residue and ventilation addresses VOCs. Cleaning does not remove VOCs that other sources release.
A volatile organic compound (VOC) is a chemical that evaporates from a solid or liquid into indoor air. The EPA lists cleaning products, disinfectants, paints, building materials and furnishings among the sources. Short-term effects include eye, nose and throat irritation, headaches, nausea and dizziness. The EPA also reports that concentrations of many VOCs run up to ten times higher indoors than outdoors.
Residue is a separate problem. CRI states that thorough rinsing is necessary to remove detergent residues that may cause rapid soiling. Residue left in the fiber is why a rinse matters.
| Term | What it is | What it affects | What limits it |
|---|---|---|---|
| VOC | Gas released from a product or material | Indoor air | Ventilation, label directions, fewer products used |
| Residue | Cleaning product left in the fiber | How fast carpet re-soils | A rinse step |
| Moisture | Water left after extraction | Dry time | Extraction and air movement |
Xtreme Cleans uses hot water extraction, a method that sprays hot water into the carpet and pulls it back out with a truck-mounted vacuum. See what steam cleaning means for the method. The carpet cleaning process guide lists the four steps of a visit.
Is carpet cleaning safe around VOCs and cleaning products?
Xtreme Cleans uses Green Seal GS-37 certified cleaning chemistry, and the EPA's advice is to increase ventilation and follow label precautions. Open a window or run the home's fans during and after the visit.
Cleaning products are used on every professional visit, and the EPA advises ventilation whenever products emit VOCs. The indoor air quality after a clean guide covers the wider air question. Green Seal GS-37 is a standard for cleaning products. Green Seal states that it covers all-purpose, glass, bathroom, carpet and enzymatic or microbial products, and that it sets VOC content limits. It is a statement about the chemistry. It does not mean the product has no VOCs, and Xtreme Cleans does not say that. The same chemistry question comes up for allergy-sensitive households.
The EPA gives the reason ventilation matters: if too little outdoor air enters a building, pollutants can accumulate to levels that can pose health and comfort problems. Households with asthma, young children or anyone who reacts to fragrance or fumes should mention it when booking. Anyone with symptoms should ask a doctor.
New carpet is a different case. CRI states that new carpet is one of the lowest-emitting products used in renovation and that its emissions drop significantly after 24 hours, sooner with fresh air. Green Label Plus is the CRI program that tests carpet, adhesive and cushion for emissions. It certifies the carpet product, not a cleaning service.
Safety also depends on how long the carpet stays wet, which is a scheduling question.
How soon can the room be used again?
Cleaned carpet dries in 2–4 hours. Walk on it once it is dry, and keep windows open or fans running while it dries.
The visit takes 1–2 hours on site for a typical three-area carpet job. The guide to what to do before the crew arrives covers access, furniture and pets.
What products do you use, and are they certified?
Xtreme Cleans uses Green Seal GS-37 certified cleaning chemistry. Every clean includes a rinse step, and no product is described as VOC-free, non-toxic or residue-free. Technicians are trained in house and background-checked.
Xtreme Cleans does not promise a carpet with no trace of product. It does not hold IICRC certification and works to the IICRC S100 standard for hot water extraction. Mineral residue from hard tap water is a separate cause, covered in the article on how hard water affects carpet cleaning.
Pet-urine treatment is a separate product that is charged separately and is not part of the base visit. See how pet-urine treatment works for that job.
How much does carpet cleaning cost in Maryland?
$199 for 3 areas, with stairs and pet-urine treatment quoted separately.
See the cost guide for how Maryland pricing is built, and the cost by room breakdown for how areas are counted.
How often should carpet be cleaned?
CRI recommends a professional deep clean every 12 to 18 months, more often in homes with pets.
Damp carpet is a separate issue covered in the mold and damp carpet guide. To book through the Maryland carpet cleaning service page, use the quote form below and mention any fragrance or fume sensitivity in the household.
Frequently asked questions
Is new carpet higher in VOCs than cleaned carpet?
The Carpet and Rug Institute states that new carpet is one of the lowest-emitting products used in renovation and that its emissions drop significantly after 24 hours, sooner with fresh air. Cleaning products are a separate source, which is why the EPA advises ventilation whenever they are used.
How do you tell if carpet has detergent residue?
Rapid re-soiling is the effect the Carpet and Rug Institute links to leftover detergent, so carpet that darkens again soon after a clean is a reason to ask about the rinse step. Xtreme Cleans finishes every clean with a rinse and does not claim a carpet with no trace of product.
Does carpet cleaning remove VOCs from the home?
No. Cleaning does not remove VOCs that other sources release, such as paints, building materials and furnishings. The EPA advises ventilation and label precautions whenever cleaning products are used.
Does Green Seal GS-37 mean the cleaning product has no VOCs?
No. Green Seal states that GS-37 covers all-purpose, glass, bathroom, carpet and enzymatic or microbial products and sets VOC content limits. It is a statement about the chemistry, not a promise of zero VOCs, and Xtreme Cleans does not claim zero VOCs.
Does leftover detergent make carpet get dirty faster?
Yes. The Carpet and Rug Institute states that detergent residue may cause rapid soiling and that thorough rinsing removes it.
