What Is Dry Cleaning? A Scientific Overview

Despite the name, dry cleaning isn’t completely dry. Rather, it avoids the use of water, relying instead on solvent-based immersion. These solvents — typically non-aqueous and non-polar — allow garments to be cleaned thoroughly without the issues caused by water exposure, such as fabric swelling, dye bleeding, or fibre warping.

The essence of what happens to your clothes in dry cleaning lies in the solvents used that effectively lift stains.

The detailed examination of what happens to your clothes in dry cleaning reveals the effectiveness of the solvents used in the process.

4 Types of Dry Cleaning Solvents

Dry cleaning uses a variety of chemical solvents instead of water to cleanse fabrics without damaging delicate fibres. These solvents vary in terms of environmental safety, cleaning power, odour, and textile compatibility. Below are the most common types:

• Perchloroethylene (Perc): This is the traditional dry cleaning solvent, widely used for decades. It is powerful and highly effective at dissolving oils and greases, making it suitable for deep cleaning. However, it is a volatile organic compound (VOC) and is considered hazardous to both the environment and human health. Regulatory pressure has led to a decline in its use.
• Hydrocarbon-Based Solvents: Derived from petroleum, these are less aggressive than perc but still effective for many common stains. They emit fewer VOCs and are considered less toxic, although they are still flammable and require careful handling. Hydrocarbon solvents are often used as a middle-ground option for cleaners seeking better environmental performance without sacrificing too much cleaning efficiency.
• GreenEarth® (Decamethylcyclopentasiloxane or D5): This silicone-based solvent is biodegradable, odourless, non-toxic, and gentle on fabrics. It is one of the most popular eco-friendly alternatives to perc and is particularly effective for delicate garments. While more expensive, its environmental benefits and customer safety make it a preferred choice for modern, sustainability-focused dry cleaners.
• Liquid CO₂: This method utilises carbon dioxide in a supercritical state, where it exhibits properties of both a gas and a liquid. It’s a highly sustainable option that leaves no chemical residue and is non-toxic. However, due to high equipment costs and technological complexity, it’s less widely adopted in commercial operations.

Each solvent type presents its balance of benefits and limitations. Selecting the right one involves weighing cleaning performance, fabric safety, cost, and environmental impact. At London Dry Cleaning, we prioritise safe and sustainable choices, using solvents like GreenEarth® to ensure both garment care and ecological responsibility.

When considering what happens to your clothes during dry cleaning, it’s crucial to evaluate the type of solvent used and its impact on various fabrics.

5 Ideal Fabrics for Dry Cleaning

The fabrics we choose to wear often dictate what happens to our clothes in dry cleaning, as delicate materials require more care.

The choice of fabric directly influences what happens to your clothes during dry cleaning; understanding this can help you select the correct cleaning method.

Dry cleaning is especially recommended for garments made from delicate, sensitive fabrics or those with a structured design that could be damaged in a traditional washing machine. These fabrics not only require special handling but also benefit from solvent-based cleaning methods that preserve their texture, colour, and shape. Here are some key examples:

• • Wool: A natural protein fibre that insulates well and resists wrinkles, but is highly vulnerable to felting and shrinkage when exposed to water and agitation. In water-based washing, wool fibres can become entangled, resulting in irreversible shrinkage and a coarse texture. Dry cleaning avoids this by using gentle agitation and non-polar solvents that prevent fibre swelling.

To appreciate what happens to your clothes in dry cleaning, one must consider the specific cleaning requirements of various fabrics.

• Silk: A luxurious fabric known for its sheen and smooth texture. Silk is susceptible to dye bleeding, fibre weakening, and water spotting when washed at home. The protein-based structure of silk can degrade under alkaline conditions. Dry cleaning protects its tensile strength and preserves its vibrant colour.
• Velvet: Composed of densely packed cut fibres that give it a plush texture, velvet is prone to pile crushing and distortion during machine washing or ironing. Dry cleaning helps maintain the upright fibres, ensuring the fabric retains its luxurious appearance and softness.
• Cashmere: A fine, lightweight wool that’s especially vulnerable to pilling, stretching, and shrinkage. Its delicate fibres can lose their softness and elasticity when exposed to water or harsh detergents. Dry cleaning maintains the fabric’s natural drape and insulating properties.
• Suede and Leather: These materials have porous surfaces that absorb water, leading to stains, stiffness, and warping. Additionally, leather can lose its natural oils and become brittle if cleaned improperly. Dry cleaning processes tailored for suede and leather include conditioning and rehydrating treatments that keep the materials supple and structurally intact.

Dry cleaning isn’t just a convenience for these fabrics — it’s a protective measure that helps maintain their longevity, form, and beauty across repeated wear.

The Dry Cleaning Process: Step-by-Step

Understanding each step of the process reveals what happens to your clothes in dry cleaning from start to finish.

1. Initial Garment Assessment and Tagging

Before any cleaning begins, each garment undergoes a detailed intake process to ensure personalised care throughout the entire dry cleaning journey. This initial assessment is crucial for identifying the fabric’s needs and preventing damage during the treatment process.

• Tagging with a Unique Identifier: Every item is assigned a unique barcode or tag upon arrival. This tracking code follows the garment throughout the cleaning cycle to prevent loss or confusion, especially in high-volume operations. It also allows the cleaner to store cleaning history, repair notes, and special handling instructions in a digital system.
• Fabric Type and Care Label Review: The care label is examined to determine the fibre composition (e.g., wool, silk, polyester) and recommended cleaning method (e.g., dry clean only, delicate cycle, no heat). Knowing the fibre type helps choose the appropriate solvent and mechanical action, thereby preventing issues such as shrinkage, colour bleeding, or fibre damage.
• Visual and Tactile Inspection: Cleaners carefully inspect each garment for stains, discolouration, loose threads, missing buttons, tears, or weakened seams. They also assess the garment’s construction — including linings, trims, shoulder pads, and embellishments — which may require special protection or removal during cleaning. Any existing defects are recorded and photographed if needed.
• Customer Notes and Special Instructions: If the customer has highlighted specific concerns (e.g., a wine stain on a blazer or sensitivity to fragrance), these are noted and included in the garment’s profile. Cleaners can then tailor the process to effectively address these needs.

This thorough evaluation ensures that every garment receives the most appropriate treatment for its material and condition, while minimising risks and maximising results.

This meticulous approach is what happens to your clothes in dry cleaning and is vital for preserving their quality.

2. Stain Identification and Pre-Treatment

Before garments enter the main cleaning phase, skilled technicians carry out one of the most critical steps: identifying and treating stains. Pre-treatment is a cornerstone of effective dry cleaning, as it can significantly influence the outcome, particularly for set-in or complex stains. This step requires knowledge of both textile chemistry and stain composition, as different types of stains react differently depending on their molecular structure and the type of fabric they’re on.

The process of identifying what happens to your clothes in dry cleaning can significantly enhance the overall cleaning results.

Technicians classify stains into chemical categories to select the appropriate solvent and technique:

• Lipophilic stains (oil-based): These include grease from food, body oils, and oil-based cosmetics like foundation and lipstick. These stains bind to fibres and are resistant to water but break down with non-polar solvents. A degreasing agent is often applied before the cleaning cycle.
• Hydrophilic stains (water-based): Examples include blood, perspiration, dairy products, and other protein-based substances. These require water-compatible agents, often enzymatic or acidic, to break down organic matter without damaging the fabric.
• Tannin-based stains (plant-derived): These include wine, tea, coffee, and fruit juices. Tannins tend to bond tightly with fibres, especially on natural fabrics like cotton and wool. Specialised tannin removers are applied, and heat must be avoided to prevent the stain from setting.
• Dyes and inks: Stains from pens, highlighters, and markers can be among the most stubborn. Solvent-based spot removers with high volatility are used to lift synthetic dyes without causing colour transfer or spreading.

Once the stain type is determined, the cleaner uses pre-spotting solutions tailored to both the stain and the fabric. Tools such as spotting boards, vacuum suction, air guns, steam jets, and brushes allow for precision treatment. Some garments may require multiple agents in sequence, starting with a mild solution and escalating if the stain proves persistent.

By understanding what happens to your clothes in dry cleaning, you can appreciate the importance of pre-treatment for effective results.

This understanding of what happens to your clothes in dry cleaning is essential for maximising the effectiveness of the entire cleaning process.

By treating stains before immersion in the primary cleaning solvent, technicians ensure that contaminants don’t become more deeply embedded or transferred across garments. This pre-treatment phase significantly enhances the overall efficacy and safety of the dry cleaning process.

3. Solvent-Based Cleaning Cycle

Once stains have been pre-treated, the garments move into the solvent-based cleaning cycle, the core phase of the dry cleaning process. This stage is performed inside a specialised machine designed to safely and thoroughly clean delicate fabrics using liquid solvents instead of water.

During the dry cleaning cycle, your clothes undergo an intricate process that ensures thorough cleaning.

Garments are loaded into a large, drum-like compartment within a closed-loop dry cleaning machine. These machines resemble commercial front-load washers but are built to handle chemical solvents and control them precisely.

• Gently agitates clothing: The machine gently rotates the garments in a solvent bath, allowing the solvent to penetrate the fibres without using the harsh mechanical agitation found in standard washing machines. This gentle action helps prevent stretching, shrinkage, and wear.
• Filters and recycles solvent: The solvent is continuously filtered through activated carbon and then spun through a distillation unit that removes impurities, reclaiming clean solvent for reuse. This closed-loop design reduces waste, minimises environmental impact, and keeps operating costs low while ensuring the garments are immersed in clean, adequate cleaning fluid throughout the cycle.
• Controls temperature and saturation: The system carefully monitors the temperature and solvent saturation levels to optimise stain breakdown without damaging fabric integrity. For example, lower temperatures are used for heat-sensitive materials such as silk or acetate. At the same time, more durable fabrics may undergo a slightly higher solvent temperature to aid in grease removal.

In addition to cleaning visible soils, this stage also removes microscopic residues such as sweat salts, pollutants, skin oils, and allergens that can cause yellowing or odour over time. The entire cycle is engineered to cleanse and rejuvenate garments while safeguarding their structure, texture, and colour.

The duration of the cleaning phase varies depending on the load size, garment types, and solvent type, typically ranging from 20 to 45 minutes. By the end of this cycle, garments are thoroughly cleaned and ready for the controlled drying phase.

4. Controlled-Temperature Drying Phase

After solvent cleaning, the dry cleaning process continues with a careful drying step.

Monitoring what happens to your clothes during the drying phase of dry cleaning is crucial for maintaining fabric quality.

After the solvent-based cleaning cycle is complete, garments are still saturated with solvent residue, which must be safely and thoroughly removed. This is accomplished through a carefully regulated drying process that uses controlled heat and airflow tailored to the specific needs of the fabric.

Inside the drying chamber of the dry cleaning machine, garments are gently tumbled while warm air circulates to evaporate the solvent. Unlike household dryers that often operate at high, uncontrolled temperatures, professional dry cleaning systems enable precise temperature adjustments. Heat levels, drum speed, and air circulation can all be finely tuned to protect the integrity of delicate materials.

Understanding what happens to your clothes in dry cleaning helps clarify the importance of controlled drying conditions.

• Temperature Control: Heat settings are chosen based on the thermal sensitivity of the fabric. For instance, low temperatures are used for silks, nylons, and spandex to prevent melting, shrinkage, or fibre weakening. Higher temperatures may be applied to cotton or wool blends that are more resilient.
• Airflow Management: The system continuously monitors and adjusts airflow to ensure uniform drying and avoid overheating any section of the garment. This helps eliminate the risk of stiffening, shrinkage, or scorching that can occur with overexposure to heat.
• Solvent Recovery: As the solvent evaporates, it is not released into the air. Instead, it’s captured by a recovery system, condensed back into liquid form, and either recycled or safely stored. This closed-loop process prevents emissions and reduces both cost and environmental impact.

This stage not only prepares the garments for the final finishing but also plays a key role in preserving their softness, flexibility, and original shape. By drying fabrics in a low-stress, highly monitored environment, professional cleaners ensure that garments emerge from this stage fresh, odour-free, and ready for pressing.

Finishing processes reflect what happens to your clothes in dry cleaning, emphasizing the attention to detail required.

5. Pressing, Shaping, and Finishing

After garments have been thoroughly cleaned and gently dried, they enter the pressing and finishing phase — a crucial stage in restoring a crisp, polished appearance and enhancing the garment’s natural drape. This phase requires expert handling, as different fabrics and garment structures demand specific techniques and tools.

Professional dry cleaners use a combination of specialised equipment and manual precision to achieve the best results:

Each step in the finishing phase reveals more about what happens to your clothes in dry cleaning.

• • Steam Presses: These machines apply high-pressure steam and heat to smooth out wrinkles, sharpen creases, and reestablish the original shape of garments. They’re ideal for structured pieces such as blazers, trousers, and skirts. Operators adjust steam levels and pressing angles depending on the garment’s thickness and fibre type.
  • Vacuum Finishing Tables: These tables not only distribute steam evenly but also utilise vacuum suction to draw moisture away from the garment quickly. This results in a cleaner press with no lingering humidity, reducing the chance of imprinting or shine on delicate fabrics.

A meticulous approach is taken with your clothes in dry cleaning, ensuring they are treated with utmost care.

• Puff Irons and Form Finishers: Puff irons are handheld tools used for intricate areas, such as collars, cuffs, and lapels, where precision is crucial. Form finishers, on the other hand, are mannequins that release steam to inflate and shape garments such as coats, jackets, and dresses from the inside out — ideal for volumetric fabrics and structured pieces that require three-dimensional shaping.

In addition to equipment, finishing often includes hand-touch-ups to smooth lining, protect buttons and embellishments, and perfect the garment’s silhouette. Garments are also carefully examined for lingering wrinkles or distortion before moving to the final inspection.

This step transforms clean garments into presentation-ready pieces that look fresh off the rack — a detail that elevates not just appearance, but wearer confidence. At London Dry Cleaning, this meticulous care is part of our commitment to quality, detail, and respect for craftsmanship.
