What Are Dry Cleaning Chemicals?
Dry cleaning is a process that cleans clothes and textiles using a chemical solvent rather than water. It's often chosen for delicate fabrics like silk, wool, and rayon that can be damaged by traditional washing machines and detergents. The term "dry" refers to the absence of water, not that the process involves no liquids at all.
The primary chemical historically used in dry cleaning is **perchloroethylene (PCE)**, often abbreviated as "perc." Perc is a colorless liquid with a distinctive, somewhat sweet odor, and it's highly effective at dissolving grease, oils, and waxes without shrinking or damaging fabrics. However, perc is also a volatile organic compound (VOC) and a suspected carcinogen, leading to increasing concerns about its environmental and health impacts.
Beyond perc, other solvents are also used in dry cleaning, especially as the industry shifts towards more environmentally friendly and health-conscious practices. These include:
Hydrocarbons: These are petroleum-based solvents, similar to mineral spirits. They are less aggressive than perc and have a lower toxicity profile but are still VOCs and flammable.
Siloxanes (e.g., decamethylcyclopentasiloxane or D5): These are silicone-based solvents that are gentle on fabrics and have a low odor. They are considered less toxic than perc but still have environmental persistence concerns.
Liquid Carbon Dioxide (CO2): This method uses pressurized liquid CO2 as the solvent. It's considered very environmentally friendly and non-toxic, leaving no chemical residue.
Wet Cleaning: While not "dry cleaning" in the traditional sense, professional wet cleaning uses specialized computer-controlled washers and dryers, along with biodegradable detergents, to clean clothes with water in a way that protects delicate fabrics. This is often promoted as the safest alternative.
Understanding which chemicals are used is key to assessing potential risks, as perc is generally the chemical of greatest concern for pregnant individuals.
Always air out dry-cleaned garments for several hours, or even a full day, in a well-ventilated area before bringing them into your living space or wearing them.
Is It Safe to Be Around Dry Cleaning Chemicals While Pregnant?
The
overarching guidance from major health organizations, including the American College of Obstetricians and Gynecologists (ACOG) and the UK's National Health Service (NHS), is to limit exposure to dry cleaning chemicals during pregnancy, particularly perchloroethylene (perc). While brief, incidental exposure, such as walking past a dry cleaner or quickly picking up clothes, is generally considered low risk, prolonged or repeated exposure is where concerns arise.
The primary risk comes from inhaling the fumes (volatile organic compounds or VOCs) released by these chemicals, especially perc, and to a lesser extent, skin contact. These chemicals can cross the placenta, meaning they can reach your developing baby. The degree of risk depends on several factors:
Type of chemical: Perc is the most scrutinized, with more evidence of potential harm at higher exposure levels compared to hydrocarbon or silicone-based solvents, or wet cleaning methods.
Concentration of chemicals: Higher concentrations of fumes pose a greater risk. This is why working in a dry cleaning facility carries significantly higher risks than simply being a customer.
Duration and frequency of exposure: Short, infrequent exposure is less concerning than long, daily exposure.
Ventilation: Poor ventilation allows chemicals to accumulate in the air, increasing inhalation risks.
For the average pregnant person, the biggest concern is often handling freshly dry-cleaned clothes that still off-gas residual chemicals. The National Institute for Occupational Safety and Health (NIOSH) and the Environmental Protection Agency (EPA) have identified perc as a potential human carcinogen and neurotoxin, which means it can affect the nervous system. While these classifications are primarily based on high-level occupational exposure, the precautionary principle during pregnancy suggests minimizing any unnecessary chemical exposure.

Safety by Trimester
The potential impact of chemical exposure can vary depending on the stage of pregnancy, primarily due to the rapid developmental changes occurring in the fetus.
Dry Cleaning Chemicals Exposure Risks First Trimester
The first trimester is the most critical period for fetal development, as this is when all major organs are forming (organogenesis). During this time, the developing baby is most vulnerable to external factors that could interfere with this complex process. High-level exposure to certain chemicals, including some found in dry cleaning, could theoretically pose a higher risk during this window. While the evidence specifically linking typical dry cleaning exposure to birth defects is limited and often based on occupational studies, it's a period where prudence is especially important. We recommend being extra vigilant about avoiding strong fumes and ensuring good ventilation if you must handle dry-cleaned items.
Second Trimester
By the second trimester, most major organs are formed, but the fetus continues to grow rapidly and mature. The brain and nervous system are still undergoing significant development. While the acute risk of major birth defects from chemical exposure may decrease compared to the first trimester, continued exposure to substances like perc could potentially impact neurological development or contribute to other adverse outcomes like low birth weight or preterm birth, though again, evidence for typical consumer exposure is limited. Maintaining precautions, such as airing out clothes and minimizing time in dry cleaning establishments, remains advisable.
Third Trimester
In the third trimester, the baby is primarily gaining weight and maturing its organ systems in preparation for birth. Exposure to chemicals during this stage could potentially affect fetal growth, respiratory development, or contribute to maternal health issues that indirectly impact the baby. While the baby is larger and perhaps less susceptible to the same developmental disruptions as in the first trimester, it's still prudent to reduce your overall chemical burden. Good ventilation and choosing safer garment care options are still recommended.
Breastfeeding
When breastfeeding, the concern shifts to whether chemicals can pass into breast milk. Perchloroethylene is known to be rapidly metabolized and excreted from the body, typically within a few days. While small amounts could theoretically transfer, the levels from typical consumer exposure are generally considered very low and unlikely to pose a significant risk to a breastfed infant. However, as a general rule, minimizing exposure to strong chemicals is always a good practice for breastfeeding parents, just as it is for anyone. If you have concerns about any chemicals and breastfeeding, consult your healthcare provider.
How Much Perchloroethylene Exposure Is Safe During Pregnancy?
When it comes to perchloroethylene (perc) and pregnancy, there isn't an officially recognized "safe" amount for direct exposure. The general recommendation from health authorities is to minimize or avoid exposure altogether, especially for pregnant individuals. This is because even at levels below those that cause immediate symptoms, there can be long-term health concerns, and the developing fetus is particularly sensitive.
The key is to understand what constitutes "exposure."
Inhalation: Breathing in fumes is the primary route of exposure. This happens most intensely in poorly ventilated areas where perc is used, such as inside a dry cleaning facility or in a small room with freshly dry-cleaned clothes.
Skin Contact: Direct contact with liquid perc or highly concentrated fumes can lead to absorption through the skin, though this is less common for consumers than inhalation.
Ingestion: Accidental ingestion is highly unlikely for consumers but would be a severe health risk.
For practical purposes, "safe limits" translate into precautionary measures:
Avoid lingering in dry cleaning establishments: Minimize the time you spend inside the store. Pick up and leave promptly.
Air out clothes: As soon as you bring dry-cleaned clothes home, remove them from the plastic bags and hang them outdoors or in a very well-ventilated area (e.g., near an open window with a fan) for several hours, or even a full day, before bringing them into your living space or closet. This allows residual perc to off-gas.
Don't store in plastic: The plastic garment bags can trap the fumes, concentrating them. Remove the bags once the clothes are aired out.
Avoid sleeping in freshly dry-cleaned clothes: Give them ample time to air out before wearing them, especially for prolonged periods like sleep.
These actions aim to reduce your personal exposure to the lowest practical level, aligning with the "better safe than sorry" approach recommended during pregnancy.
Proper ventilation is key when dealing with any cleaning chemicals or freshly dry-cleaned garments. Open windows and use fans to ensure fresh air circulation.
Side Effects and Risks
The potential side effects and risks associated with dry cleaning chemicals, especially perchloroethylene (perc), vary significantly based on the level, duration, and type of exposure. Most serious risks are linked to high, prolonged occupational exposure rather than typical consumer contact.
For the Mother (from high or prolonged exposure)
Acute Symptoms: Inhaling high concentrations of perc fumes can cause dizziness, headaches, nausea, lightheadedness, and impaired coordination. These symptoms are usually temporary and resolve once exposure stops.
Respiratory Irritation: Fumes can irritate the eyes, nose, throat, and lungs, leading to coughing or difficulty breathing.
Skin Irritation: Direct skin contact with liquid perc can cause redness, dryness, and irritation because it strips away natural oils.
Neurological Effects: Long-term, high-level exposure has been linked to neurological issues, including memory problems and cognitive impairment.
Cancer Risk: The International Agency for Research on Cancer (IARC) classifies perc as "probably carcinogenic to humans" (Group 2A), based on evidence from occupational studies. This risk is primarily associated with long-term, high-level exposure, not occasional consumer use.
For the Developing Baby (from high or prolonged maternal exposure)
It's crucial to distinguish between theoretical risks from high-level exposure and the very low risks associated with typical consumer contact.
Low Birth Weight and Preterm Birth: Some studies, primarily involving pregnant individuals working in dry cleaning facilities, have suggested a potential association between high perc exposure and an increased risk of low birth weight or preterm delivery. However, these findings are not universally consistent, and the direct causal link from typical consumer exposure is not established.
Developmental Concerns: Perc is a neurotoxin, meaning it can affect the nervous system. There are theoretical concerns that high maternal exposure could potentially impact fetal neurological development. However, definite links to specific birth defects or developmental delays from typical consumer exposure have not been established. A teratogen is a substance that can cause birth defects; while perc is a suspected carcinogen and neurotoxin, it is not definitively classified as a human teratogen at typical environmental exposure levels.
Miscarriage: While severe chemical exposure in general can be a concern for pregnancy loss, there is no strong evidence to suggest that typical consumer exposure to dry cleaning chemicals directly causes miscarriage. Occupational studies exploring this link have yielded mixed results, and any observed associations often involve very high levels of exposure or confounding factors.
Given these potential risks, even if largely associated with high-level exposure, the precautionary principle is applied during pregnancy. Minimizing exposure is a simple, effective step to reduce any potential concerns.

Safe Alternatives to Dry Cleaning Clothes When Pregnant
Navigating garment care during pregnancy doesn't have to mean sacrificing your delicate clothes. There are many safer alternatives to traditional dry cleaning that can help you minimize exposure to harsh chemicals.
Hand Washing Delicate Garments: Many items labeled "dry clean only" can actually be hand-washed with care. Use cool water and a mild, pH-neutral detergent specifically designed for delicates (like wool wash or baby shampoo). Gently swirl the garment, rinse thoroughly, and roll it in a clean towel to absorb excess water before laying it flat to dry.
Home Dry Cleaning Kits: These kits typically use a scented cloth and a bag that goes into your home dryer. They generally rely on water, heat, and milder solvents than professional dry cleaning. Always check the ingredients list carefully for any chemicals you're uncomfortable with, and ensure excellent ventilation during use.
Steaming Clothes for Freshness: A garment steamer is excellent for removing wrinkles and refreshing clothes between washes. The hot steam can kill bacteria and eliminate odors without any chemicals. This is a great way to extend the life of garments that aren't truly dirty but just need a refresh.
Professional Wet Cleaning Services: Many modern dry cleaners now offer "wet cleaning," which uses specialized water-based systems, biodegradable detergents, and precise temperature and moisture controls to clean delicate fabrics. This method is environmentally friendly and chemical-free, making it a much safer choice for pregnant individuals.
Airing Out Clothes Outdoors: For items that aren't stained but just need to be freshened, hanging them outdoors on a clothesline or on a hanger in a breezy spot for a few hours can work wonders. Sunlight and fresh air naturally deodorize fabrics.
Spot Cleaning with Mild, Non-Toxic Solutions: For small stains, target the area with a mild, non-toxic stain remover (check labels for pregnancy safety) or a diluted solution of gentle soap and water. Always test on an inconspicuous area first. For general household cleaning, refer to our guide on Cleaning Supplies Safe for Pregnancy: What’s Safe, What to Limit.
Using Garment Bags for Storage: Storing delicate or out-of-season clothes in breathable garment bags (made of cotton or non-woven fabric, not plastic) can protect them from dust and pests without the need for mothballs or other chemical treatments.
Choosing Machine-Washable Fabrics: When buying new clothes, especially during pregnancy, prioritize fabrics that are easy to care for at home. Look for items made of washable wool, rayon, Tencel, or blends that can go into your regular laundry cycle.

Myth vs. Fact
When it comes to chemical exposure during pregnancy, misinformation can cause unnecessary stress. Let's clear up some common myths about dry cleaning chemicals.
Myth: All dry cleaning methods are equally risky, so I should avoid all dry cleaners.
Fact: Not all dry cleaning methods use the same chemicals. While traditional dry cleaning often uses perchloroethylene (perc), many modern dry cleaners are shifting to safer alternatives like hydrocarbon solvents, silicone-based solvents, liquid CO2, or professional wet cleaning. Wet cleaning, in particular, uses water and biodegradable detergents and is considered a very safe option. It's always a good idea to ask your dry cleaner about the methods and chemicals they use.
Myth: Once my clothes are home from the dry cleaner, they are completely safe and free of chemicals.
Fact: Freshly dry-cleaned clothes can continue to "off-gas" residual chemicals, especially perchloroethylene, for several hours or even days after you bring them home. Trapping them in the plastic garment bag can concentrate these fumes. It's crucial to remove the plastic bags immediately and hang the clothes in a well-ventilated area (like outdoors or near an open window) for at least several hours before putting them in your closet or wearing them.
Myth: If I can't smell dry cleaning fumes, there's no risk.
Fact: While a strong chemical odor is a clear indicator of active off-gassing and higher concentrations of fumes, some volatile organic compounds (VOCs) can be present in the air even if you can't detect a strong smell. Your sense of smell can also become desensitized over time. Therefore, relying solely on your nose isn't a foolproof way to gauge safety. Following precautions like airing out clothes and ensuring good ventilation is important regardless of perceived odor.
Key Takeaways
It's best to limit direct and prolonged exposure to dry cleaning chemicals, especially perchloroethylene (perc), during pregnancy.
Brief, incidental exposure (e.g., walking past a dry cleaner) is generally considered low risk.
Always air out freshly dry-cleaned clothes for several hours in a well-ventilated area before bringing them indoors or wearing them.
Consider safer alternatives like hand washing, home dry cleaning kits (checking ingredients), steaming, or professional wet cleaning services.
The first trimester is the most sensitive period for fetal development, making precautions especially important then.
If you work in a dry cleaning environment, discuss your pregnancy with your employer and healthcare provider to ensure necessary safety measures are in place or to consider alternative duties.
Frequently Asked Questions
Is it safe to wear dry cleaned clothes while pregnant?
Yes, it is generally considered safe to wear dry cleaned clothes while pregnant, provided you take a key precaution: always air them out thoroughly first.
