You’d expect to see these warnings on a barrel of hazardous waste. In fact, they’re in the fine print of labels of everyday household cleaners or on their websites and obscure technical disclosures.

In a ground-breaking initiative to uncover the truth about toxic chemicals in common household products, the Environmental Working Group has unearthed compelling evidence that hundreds of cleaners, even some of those hyped as “green” or “natural,” can inflict serious harm on unwary users. Many present severe risks to children who may ingest or spill them or breathe their fumes. Read more…

Simple Green Concentrated All-Purpose Cleaner

It’s labeled “non-toxic” and “biodegradable.” It contains:

• 2-butoxyethanol, a solvent absorbed through the skin that damages red blood cells and irritates eyes;
• A secret blend of alcohol ethoxylate surfactants. Some members of this chemical family are banned in the European Union.

Worse, the company website instructs the user to dilute the product significantly for even the heaviest cleaning tasks. Yet it comes in a spray bottle that implies it should be sprayed full-strength. Such use would result in higher exposures.

Whink Rust Stain Remover

Advertised for cleaning white porcelain sinks, toilet bowls and colorfast fabrics and carpet, the fine print warns:

• “May be fatal or cause permanent damage.”
• “Causes severe burns which may not be immediately painful or visible.”
• On technical information for workers, “will penetrate skin and attack underlying tissues and bone.”

Product literature advises workers to “use only with adequate ventilation” and to wear gloves, safety goggles and a face mask. Consumers are advised only to wear rubber gloves.

Citra-Solv Cleaner & Degreaser

These concentrated liquids and ready-to-use sprays contain d-limonene and orange oils from citrus peels. According to the company’s worker safety disclosure, Citra-Solv concentrate is 85 to 95 percent d-limonene. That the oils are derived from citrus implies safety, but sprayed into the air, they can react with trace levels of ozone air pollution to form ultra-fine particles that penetrate deep into the lungs and formaldehyde, which the U.S. government classifies as a known human carcinogen. The California Air Resources Board advises people to limit the use of citrus- or pine oil-based cleaners on smoggy days to avoid exposure to particulates and formaldehyde.

EWG Green Tip:

Read labels carefully and pay special attention to warnings. Don’t buy any products labeled “poison,” “danger” or “fatal” if swallowed or inhaled.

Spic and Span Multi-Surface and Floor Cleaner

This product contains nonylphenol ethoxylate, which the state of California has banned in cleaning products manufactured after 2012. Products containing this chemical cannot be sold in the European Union. It breaks down to nonylphenol, which can disrupt the hormone system, is toxic to aquatic life and persists in the environment.

Scrubbing Bubbles – Antibacterial Bathroom Cleaner & Extend-A-Clean Mega Shower Foamer

These products contain up to 10 percent DEGBE, also called butoxydiglycol, a solvent banned in the European Union at concentrations above 3 percent in aerosol cleaners. It can irritate and inflame the lungs.

Mop & Glo Multi-Surface Floor Cleaner

It contains DEGME, also called methoxydiglycol, at up to 15 times the concentration allowed in cleaners sold in the European Union. The United Nations Economic Commission for Europe says DEGME is “suspected of damaging the unborn child.” (This product is also sold as “Mop & Glo Triple Action Floor Shine.”)

DampRid Mildew Stain Remover Plus Blocker

It may contain up to 10 percent of a hazardous solvent called 2-butoxyethanol. Canada caps this chemical’s use in non-aerosol cleaners at 6 percent. It also contains nonylphenol ethoxylate, prohibited in cleaners sold in the E.U.

EASY-OFF Fume Free Oven Cleaner

This spray contains 5 to 10 percent DEGBE. The E.U. bars concentrations of DEGBE greater than 3 percent because it can harm the lungs.

EWG Green Tip:

Check your brands’ labels and websites for ingredient lists. Avoid products containing nonylphenol ethoxylates (look for “nonylphen” or “nonoxynol” within the ingredient name) and 2-butoxyethanol, butoxydiglycol, ethylene- or diethylene glycol monobutyl ether, diethylene glycol monomethyl ether or methoxydiglycol.

Drano Professional Strength Kitchen Crystals Clog Remover

The label says this product can severely burn eyes and skin and cause blindness or even death. Drano Kitchen Crystals may remain in the drain after use, creating an extreme hazard. Using a plunger could cause caustic splashback. Pouring any other product down the drain might trigger a dangerous chemical reaction. The label warns purchasers to “keep water out of can at all times to prevent contents from violently erupting or boiling out.” Yet unsuspecting consumers have been known to store it under the sink.

EWG Green Tip:

Use a drain snake and plunger, available in hardware stores. Store drain cleaner in high secure cabinets out of reach of children and away from water.

Walmart Great Value Heavy Duty Oven & Grill Cleaner

The label warns: “Will burn skin and eyes. Avoid contact with skin, eyes, mucous membranes and clothing. Harmful if swallowed. Avoid inhaling spray mist. Wear long rubber gloves while using…”

CVS/pharmacy Fume-Free Oven Cleaner

Though claiming to be “fume-free,” the label warns: “Vapor harmful… open windows and doors or use other means to ensure fresh air entry during application and drying.” The label says the product contains an unidentified substance “known to the state of California to cause cancer.”

EASY-OFF Heavy Duty Oven Cleaner Aerosol Spray

The label warns: “Warning: …DANGER: CORROSIVE…WILL BURN EYES AND SKIN. HARMFUL IF SWALLOWED. Avoid contact with eyes, skin, mucous membranes and clothing. DO NOT ingest. Use only with adequate ventilation. Avoid breathing spray mist. Wear long rubber gloves when using…”

EWG Green Tip:

Sprinkle baking soda liberally to cover the bottom of the oven. Spray with water. Wait 8 hours, scrape and wipe clean.

Target’s Up & Up

This brand’s Toilet Bowl Cleaner and Glass and Surface Wipes do not list any ingredients on the product packaging. Other products sold under the Up & Up label list only one or two ingredients or use vague terms.

LA’s Totally Awesome

This brand divulges few ingredients. It lists just one ingredient for its Orange All Purpose Degreaser & Spot Remover, the hazardous solvent 2-butoxyethanol.

Walmart’s Great Value

This store brand does not list ingredients in its Heavy Duty Oven & Grill Cleaner and lemon-scented Furniture Polish, despite the company’s commitment “to sell products that sustain people and the environment.” Other items sold under the Great Value brand list few ingredients or use general terms for them.

EWG Green Tip:

Look for products listing most or all ingredients on the label or website. No information could mean something to hide.

Glade Air Freshener Sprays, Air Wick automatic air fresheners, and Old English furniture polish

These products warn that “intentional misuse by deliberately concentrating and inhaling the contents can be harmful or fatal.”

Spot Shot Carpet Stain Remover

This product warns that “inhalation abuse of aerosol products may be harmful or fatal.”

EWG Green Tip:

Talk to your kids about the risks of inhalants (www.inhalant.org). Read warning labels and keep cleaners that are potentially fatal if inhaled out of your home.

Lysol Disinfectant Power Toilet Bowl Cleaner with Lime & Rust Remover

This corrosive acid concoction kills bacteria but is also labeled “harmful or fatal if swallowed.” The cleaner’s child-proof cap is an important safety feature. The label warns not to squeeze the container when opening and to wear safety goggles. A bit of this acid in the eye can cause “irreversible damage.”

2000 Flushes and X-14 toilet bowl cleaners

These chlorine-laden discs don’t harm plumbing or septic systems, but according to the label they “may be fatal if swallowed.” The boxes warn customers to wear rubber gloves when handling, hold the disc away from the face and avoid inhaling the fumes. A pet could confuse a disc with a plastic chew toy.

EWG Green Tip:

Don’t take a chance on products that are fatal if swallowed. Pets and children are most at risk, so read the warning labels. Stock your cabinet with safer choices, but keep them, too, out of children’s reach.

Hagerty Liquid Jewel Clean

It contains perchloroethylene, a toxic solvent classified as “probably carcinogenic to humans” by the International Agency for Research on Cancer.

Tarn-X Tarnish Remover

This “Wipe & Rinse” product contains up to 7 percent thiourea, a chemical classified as a carcinogen by the state of California. The company’s technical information for workers says “prolonged or repeated exposure may cause reproductive and fetal effects.”

Ajax, Dynamo and Fab Ultra liquid laundry detergents (Phoenix Brands)

These contain formaldehyde, also known as formalin, classified as a known human carcinogen by the U.S. government and World Health Organization. Formaldehyde can cause asthma and allergies. The company divulges the presence of formaldehyde in the product only on technical disclosures for workers.

EWG Green Tip:

Try safer do-it-yourself options first, before heavier duty options.

Static Guard

This product contains the chemical DTDMAC, or ditallow dimethyl ammonium chloride, which is so persistent in the environment that it can’t be used as a cleaning ingredient in the European Union.

Final Touch Ultra Liquid Fabric Softener

This brand contains quaternium-18 (dihydrogenated tallow dimethyl ammonium chloride or DHTDMAC), which also cannot be used in cleaning products sold in the European Union because of its persistence in the environment.

EWG Green Tip:

Use a humidifier if your indoor air is dry – more water in the air means less static electricity. Add vinegar to the rinse cycle to prevent static cling or run a damp cloth over clothing.

Clorox, Fantastik, Febreze, Formula 409, Easy-Off, Lysol, Mr. Clean and Spic and Span.

Many of the spray cleaners sold under these brand names are laced with quaternary ammonium compounds or ethanolamine, ingredients classified as asthmagens by the Association of Occupational and Environmental Clinics, a professional association of clinics and health experts. These chemicals can trigger asthma attacks and can cause new cases of the disease in people who are asthma-free. Ingredients classified as asthmagens don’t belong in spray products.

EWG Green Tip:

Skip spray products that contain ethanolamines (MEA, DEA and TEA) and “quats.” Beware of ADBAC, benzalkonium chloride or ingredients with “-monium chloride” in the name from the label or the company’s website. Do not use disinfecting sprays, since most of them contain asthmagens.

Comet Disinfectant Cleanser Powder

This product emitted 146 different chemicals, including some thought to cause cancer, asthma and reproductive disorders. The most toxic chemicals detected – formaldehyde, benzene, chloroform and toluene – are not listed on the label. Little is known about the health risks of most of the contaminants found.

Febreze Air Effects

This product released 89 air contaminants.

EWG Green Tip:

Open windows or run a fan – or both – to clear the air during and after cleaning.

Lysol Neutra Air Freshmatic

This product boasts that “your home will always smell fresh and clean” but cautions that the device should be placed “in well-ventilated rooms away from sleeping areas.” Among the label’s warnings: may be harmful if directly inhaled, may cause allergic reaction in some individuals, DO NOT spray towards face or body, DO NOT get in eyes, avoid content with skin, DO NOT spray directly onto surfaces.

Air Wick Freshmatic Compact

This product cautions to “use in well-ventilated rooms away from sleeping areas.”

Febreze and Glade automatic air fresheners

These products warn, “Do not use in small confined pet areas without adequate ventilation.”

EWG Green Tip:

If a room has an odor problem, track down the source and eliminate it instead of covering it up with fragrances. A bowl of baking soda in the bathroom can absorb odors.

FINISH Glass Magic Hardwater Performance Booster

This product contains up to 21 percent phosphate by weight, according to the label.

EWG Green Tip:

Skip phosphate additives for dishwashers and clothes washers. Don’t use cleaners with ingredients that damage the environment.
