Understanding The Need for Dry Cleaning
Dry cleaning, or dry clean, is a specialised cleaning method that uses chemical solvents instead of water to clean clothes and other fabrics. But what are the chemicals used in dry cleaning?Â
The most common dry cleaning solvent is perchloroethylene (PERC), although some dry cleaners also use hydrocarbon dry cleaning agents like DF-2000™ Fluid and EcoSolv®. These dry cleaning chemicals effectively remove oil-based stains, dirt, and other contaminants from clothing without causing colours to fade or damaging delicate fabrics.
Benefits of Dry Cleaning:
Gentle on fabrics: Dry cleaning is gentler on fabrics than traditional water-based cleaning methods, making it ideal for delicate materials like silk, wool, and lace.
Effective stain removal: The chemical solvents used in dry cleaning are highly effective at removing stubborn stains, such as grease, oil, and makeup.
Preserves shape and colour: Dry cleaning helps garments retain their original shape and colour, preventing shrinkage or fading that can occur with water-based washing.

Common Types of Dry Cleaning Chemicals
In our experience at Industry Kitchens, we've come across an array including perchloroethylene (perc), hydrocarbons and even some environmentally friendly alternatives like liquid carbon dioxide or dipropylene glycol tertiary butyl ether (a type of glycol ether).
Perc has been a popular choice among cleaners because it's excellent at dissolving oils and greases without causing shrinkage or colour loss in most textiles. According to statistics, perc was used in 80% of dry-cleaning operations until recently when concerns arose regarding its environmental impact leading many businesses towards safer options such as liquid silicone or CO2-based methods. Did you know dipropylene glycol tertiary butyl ether, despite being less common than perc, are biodegradable detergents with a higher flashpoint making it safer to use?
Understanding the chemicals behind your clothes' dry cleaning can be quite an adventure, revealing how much thought goes into preserving that favourite dress or tailored suit of yours. The decision to utilise traditional solvents or eco-friendly alternatives frequently relies upon individual inclinations, considering aspects such as cost, effectiveness and greenness.
Key Takeaway:Â
What are the chemicals used in dry cleaning? There's a range of options available, from traditional solvents to eco-friendly solutions. So whether you're tackling tough stains or just looking for a refresh, knowing about these cleaning agents can really enhance your understanding of dry cleaning.
Perchloroethylene (PERC) - The Most Common Solvent
As you dive into the world of dry cleaning, one chemical name pops up more than others: Perchloroethylene. Known in the trade as PERC, this solvent has been an industry standard for decades.
Regulations are tight, and with good reason. PERC is a suspected cancer-causing agent. This puts a legal responsibility on all dry cleaners to protect their staff and environment from these chemicals.
The power of perchloroethylene lies in its ability to dissolve oils and greases, something water can struggle with. It's volatile too which means it evaporates quickly leaving your clothes clean and dry after treatment.
A Deeper Dive Into PERC Properties
Let's get down to brass tacks here – why is Perc so popular? Well, it's a chlorinated hydrocarbon that boils at around 121 degrees Celsius. Its high boiling point combined with low flammability makes it ideal for use within dry cleaning machines.
Bear in mind though; there’s no such thing as a free lunch. While perc does indeed have a higher flashpoint compared to other solvents, making fires less likely during the cleaning process, overexposure could be detrimental due to potential health risks involved.
Potential Health Risks Associated With PERC Exposure
This brings us neatly to another key aspect we need to consider when talking about Perc – health implications. Despite being an effective cleaner, repeated exposure may lead to adverse effects like dizziness or even certain types of cancers according to some studies.
Given its effectiveness, one might question why Perc is still in use despite potential health implications. That being said, industry and regulatory bodies are actively working to find alternatives that balance effectiveness with health and environmental considerations.
In fact, many dry cleaners have already started making the switch towards more environmentally friendly solvents – but we'll save that topic for another day.
Key Takeaway:Â
Perchloroethylene (PERC) is a popular solvent in dry cleaning due to its oil-dissolving properties and quick evaporation, leaving clothes clean. However, despite PERC's effectiveness, it carries potential health risks including dizziness and even cancer. Consequently, many are seeking alternatives that balance cleaning efficiency with health safety and environmental friendliness.
Hydrocarbons - A Traditional Choice for Dry Cleaning
What are the chemicals used in dry cleaning, you ask? Long before the arrival of more complex chemicals, hydrocarbon solvents were widely used in dry cleaning operations. This class of chemical compounds is a traditional choice, mainly because they are less aggressive and hence cause minimal damage to delicate clothing pieces.
The term 'hydrocarbon' might sound like something straight out of your high school chemistry textbook but don't worry; it's not as complicated as you think. In simple terms, these solvents contain only carbon and hydrogen atoms. Their use dates back centuries when people discovered that they could clean clothes without making them wet.
One characteristic feature of hydrocarbons, particularly those used in dry cleaning services, is their higher flashpoint compared to other solvents such as perchloroethylene (perc). This means hydrocarbons catch fire at higher temperatures which reduces risk during the cleaning process.
Detailed Examination: Hydrocarbon Solvent Features
You can observe that every dissolvent has its own particular advantages and disadvantages contingent upon how it collaborates with various materials. So what makes hydrocarbons tick? Let's delve deeper into some key features:
Gentleness: Compared to perc or glycol ethers, for instance, hydrocarbons tend to be gentler on fabrics due to their milder nature.
Cleaning Cycle Time: One interesting fact about this traditional solvent is that it requires a longer cycle time than others. (Don’t mistake this slower pace for inefficiency though.)
Risk Reduction: As mentioned earlier, the relatively high flashpoint significantly reduces the risk of fires during dry cleaning operations.
However, hydrocarbon solvents are not without their drawbacks - they may be less effective in removing certain stains and can leave an oily residue on fabrics. For instance, these solvents are not as effective in removing certain stains and can sometimes leave an oily residue on fabrics. But hey, no solvent is perfect.
Key Takeaway:Â
Impact of Dry Cleaning Chemicals on Human Health and Environment
The cleaning chemicals used in dry cleaning operations, particularly Perchloroethylene (PERC), are not only tough on stains but also on human health. Short-term exposure to PERC can cause dizziness and headaches in humans. However, the dangers posed by PERC are far from limited.
This common dry cleaner solvent is a suspected carcinogen. As such, all dry cleaners have a legal responsibility to protect their staff and the environment from these harmful effects as per the Environmentally Hazardous Chemicals Regulation 2017.
Apart from human health issues, air pollution caused by these solvents is another area of concern. Emissions from some older or poorly maintained machines contribute significantly to poor air quality around us.
Health Impact: Beyond Immediate Symptoms
Beyond immediate symptoms like dizziness, long-term exposure has been linked with more serious conditions including liver damage and even cancer.
Interestingly though, it's not just workers at risk here; people who regularly get their clothes dry cleaned may be exposed too. These toxins can linger in clothing pieces after they've been treated, making them potential sources of indoor pollution.
Tackling Environmental Issues
Dry cleaning chemicals do pose environmental challenges - they're difficult to dispose of safely largely because most are non-biodegradable.
In response, however, industry standards have evolved over time aiming for more environmentally friendly alternatives such as liquid carbon dioxide or glycol tertiary butyl ether that carry fewer health risks without compromising the effectiveness of stain removal. Kelly’s Dry Cleaners, for example, has adopted an environmentally friendly alternative to traditional cleaning solvents.
Remember, when we take care of our clothes, we're not just ensuring they look their best - we’re also playing a role in protecting human health and the environment.

Key Takeaway:Â
Long-used in dry cleaning, hydrocarbon solvents are a gentler option that helps preserve delicate clothing. They're made of simple carbon and hydrogen atoms and have a higher flashpoint for safer cleaning operations. But they do take longer to clean with, aren't as effective on some stains, and can sometimes leave an undesirable residue.
The Dry Cleaning Process
So, we've answered our main question: "What are the chemicals used in dry cleaning?". Let's talk about how dry cleaning works and the role of chemicals in the process.
The dry cleaning process involves several steps to ensure clothes are thoroughly cleaned and free of stains and odours. Here's a quick step-by-step guide:
Pre-treatment: Visible stains and spots are treated with specialised cleaning agents and spotting chemicals.
Loading: Garments are loaded into the dry cleaning machines.
Cleaning cycle: The machine agitates the clothes in the dry cleaning fluid, allowing it to penetrate and dissolve dirt and oils.
Drying: The solvent is drained, and the clothes are transferred to a separate dryer to remove any remaining chemical dry cleaning solvent.
Finishing: Dry cleaned clothes are pressed and finished to restore their original shape and remove wrinkles.
Key Takeaway:Â
Understanding the process is crucial to learning what are the chemicals used in dry cleaning because each step relies on specific solvents to clean and treat fabrics effectively. The chemicals used in dry cleaning, such as PERC and hydrocarbon solvents, play a vital role in removing stains, dissolving oils, and ensuring garments come out fresh and wrinkle-free.
Green Alternatives to Traditional Solvents
So, what are the chemicals used in dry cleaning that are eco-friendly? The dry cleaning industry is turning over a new leaf, shifting from traditional solvents like perc and hydrocarbons towards more eco-friendly options.
Liquid Carbon Dioxide (CO2) Cleaning
Liquid carbon dioxide (CO2) cleaning is an environmentally friendly alternative to traditional solvents.
