This fact sheet discusses environmental concerns related to the carpet cleaning industry. Information presented in this fact sheet is intended to provide a general understanding of the statutory and regulatory requirements governing the carpet cleaning industry. This information is not intended to replace, limit, or expand upon the complete statutory and regulatory requirements presented in the California Environmental Protection Act.

Because carpet cleaning generates wastewater, it is your responsibility to properly manage and dispose of this byproduct. This fact sheet discusses how the carpet cleaning industry operates, why wastewater is a concern, ways to properly dispose of wastewater, and offers suggestions on environmentally friendly carpet cleaning processes. Contact information is presented at the end of this fact sheet.

How Does the Carpet Cleaning Industry Operate?

Depending on the location of the carpet or the type of treatment required for the carpet, two different carpet cleaning processes may be used.

• “Dry” cleaning uses a minimal amount of liquid and a blend of compounds for restorative cleaning, regular scheduled maintenance, and emergency cleanup. This process uses a homogenized blend of solvents, including a cleaning agent, rinsing agent, and neutralizing agent, heated to about 200 degrees Fahrenheit and applied to the carpet.
• Steam extraction is commonly used for restoration jobs. This truck-mounted system uses antimicrobial, urine and odor treatment chemicals. This process uses the same chemicals used in “dry” cleaning, but the rinsing agent is blended in the truck-mount, and more water is used in rinsing.

Industry standards exist for upholstery, carpet and other cleaning procedures. Carpet cleaning requires the following procedures: vacuuming, pretreatment and conditioning, extraction, nap setting, and drying. Vacuuming removes most particulate soil, pretreatment and conditioning loosen soil with a mild solvent cleaner, extraction rinses away the cleaning solvent, and nap setting and drying allow the remaining solvent to vaporize and dry. If these procedures are not followed, indoor air quality could pose a health concern both for the cleaner and those at the residence or business.

Why is Discharging Wastewater from Carpet Cleaning a Concern?

Carpet cleaning creates wastewater that includes chemicals from the cleaning formula as well as waste products such as grease and organic matter from the carpet itself. Many chemicals currently used are highly alkaline and aggressive enzymes and disinfectants which if used or managed improperly can cause harm to humans and the environment. A standard cleaning formula may contain a high concentration of sodium bicarbonate and lower concentrations of sodium citrate, sodium phosphate, sodium silicate, anionic surfactant, and nonionic surfactant . Formulas can also contain dyes, polymers, enzymes, bleaches, and solvents of alcohols, esters, and glycol ethers. Some specialized cleaners also contain various forms of butyl, such as butyloxy ethanol (also known as butyl cellusolve) used in the “dry” cleaning method of carpet cleaning. This chemical can damage the central nervous system, kidneys, liver and blood.

What Should I Do with My Carpet Cleaning Wastewater Discharge?

Some storm drain systems discharge untreated water directly to water bodies. When untreated wastewater is discharged to a storm drain of this sort, chemicals from the cleaning formula and products in the wastewater could contaminate water bodies. The suggestions listed below for carpet cleaning can reduce the amount of pollutants discharged to water bodies through storm sewers.

• Use a portable containment system. Wastewater can be kept in a holding tank to be hauled off-site and properly disposed of. Wastewater should not be discharged onto the ground or into any surface water body.
• Find out if area storm and sanitary sewers are combined or separate. Many storm and sanitary sewers in the Metropolitan Water Reclamation District of Los Angeles) are combined before their final discharge point; therefore, most wastewater is treated before it is discharged to water bodies. Newer areas and other Illinois cities may have separate systems; therefore, wastewater discharged to storm sewers can contaminate water bodies. Contact your local publicly owned treatment works to find out if the storm and sanitary sewer systems are combined or separate.
• Discharge wastewater to the sanitary sewer of the property where the cleaning is conducted with permission of the property owner. The on-site sanitary sewer can be accessed through a building drain, building sewer, industrial sink, private sewer cleanout, private sampling manhole, or any other privately owned sanitary sewer access point. Discharges to the sewer should not contain grease, grit, or any material that could clog piping. A specific pH range may also be required of the discharge. For example, discharges to the sanitary sewer must have a pH of 5.0 to 10.0. Call the local POTW in the area where you are working for information on storm sewers and associated discharge requirements.

Do I Need a Permit for my Carpet Cleaning Wastewater Discharge?

Carpet cleaning wastewater can be discharged to the sanitary sewer system with permission from the local publicly owned treatment works (POTW). Contact your local POTW to find out their requirements. We recommend you do not discharge your carpet cleaning wastewater to a septic system; however, if you plan to, you must contact the Illinois Department of Public Health and Illinois EPA. Because regulations on carpet cleaning wastewater vary from city to city, it is wise to contact the city storm water program or department to determine exact permit requirements.

How Can I Clean Carpets Using a More Environmentally Friendly Process?

Practical, nontoxic alternatives to standard carpet cleaning products are labeled as “green” cleaning agents. Some “green” carpet cleaning products do not contain butyl cellusolve. By using environmentally safe chemicals to clean carpets, the cleaner and others at the business or residence are not exposed to toxic chemicals. The “green” cleaning agents are also safe for the cleaner to handle. It is important for the cleaners to follow the Institute of Inspection, Cleaning and Restoration Certification standards when using “green” products. These standards can be ordered online at www.iicrc.org. Also, carpets can be thoroughly cleaned using high temperatures (up to 260 degrees Fahrenheit) and mild chemical agents.

Commercial spot removers for carpets and rugs usually contain caustic substances, not to mention chlorine and/or petroleum-bas­ed solvents. Although more and more spot removers are becoming available that claim to be easy on both the environment and your health, there’s really no need for you to buy them. Luckily, you can tackle many of the common carpet and rug stains you may encounter with a vinegar and water solution, and sometimes with just undiluted vinegar alone! To get that coveted foaming action that many products feature, place the vinegar solution into a well-rinsed foaming soap bottle.

Now, let’s look at some specific situations where green cleaning can be applied to the carpet.

With kids in the house, you might find chewing gum or crayon stains mysteriously appearing in your rug or carpet (try finding a kid to own up to them!). For each of these, you need to use undiluted vinegar. To remove crayon stains, tackle the spot directly by dipping an old toothbrush in vinegar and scrubbing the stained area.

If you find a dried blob of white school glue on your carpet, try treating it with a vinegar and water solution sponged in and blotted. However, if the spot is stubborn, warm up the vinegar a little bit on the stove or in your microwave and sponge it in undiluted. Let it sit for 10 to 15 minutes, then scrape it away. Clean up any residue using the vinegar and water solution.

Here’s an excellent way to pick up a greasy spill on your carpet: Sprinkle it with a li­ttle cornmeal and allow it to sit for five minutes. Next, sponge the area with vinegar and water.

When your rug or carpet is stained with any one of the Four Cs, a vinegar and water s­olution is called for. Remember, though, that each culprit requires an individual application guideline. For each, first mix 1 cup vinegar with 2 cups water (or a 1:2 ratio of any kind, depending upon the quantity you need).

For catsup, liberally sponge the mixture into the carpet until the stain disappears, rinsing and repeatedly wringing out your sponge.

Chocolate stains should be treated in the same way, but it’s important to blot with a clean cloth, rather than rub, to avoid spreading the stain further. Again, rinse and wring out your sponge repeatedly until the water runs clear.

A coffee or tea spill on the rug should come up easily if you catch it right away. Just sponge it with clean water. If the stain is set, however, use the vinegar and water solution; sponge it in, then rinse and wring until all brown color is gone. You can treat dark cola stains in the same way.
